Maintenance Button
The Maintenance button is a dual-function momentary switch on the front
panel. Its purpose is to reset the switch module or to place the switch module
in maintenance mode. Maintenance mode sets the IP address to 10.0.0.1 and
provides access to the switch module for maintenance purposes when flash
memory or the resident configuration file is corrupted. Refer to “Recovering a
Switch Module” on page 4-4 for more information about using maintenance
mode.
Resetting a Switch
To reset the switch module, use a pointed tool to momentarily press and
release (less than 2 seconds) the Maintenance button. The switch module will
respond as follows:
1. All switch module LEDs will illuminate, then the System Fault LED
extinguishes leaving only the Input Power LED illuminated.
2. After approximately 1 minute, the power-on self test (POST) begins.
3. When the POST is complete, the Input Power LED is illuminated.
Placing the Switch in Maintenance Mode
To place the switch module in maintenance mode, do the following:
1. Isolate the switch module from the fabric.
2. Press and hold the Maintenance button with a pointed tool for 2–4
seconds.
3. After a few seconds, the POST begins illuminating all switch module
LEDs.
4. When the POST is complete, the switch module LEDs extinguish.

The Input Power LED indicates the voltage status at the switch module logic
circuitry. During normal operation, this LED illuminates to indicate that the
switch module logic circuitry is receiving the proper DC voltages. When the
switch module is in maintenance mode, this LED is extinguished.
System Fault LED (Amber)
The System Fault LED illuminates to indicate an over temperature condition
or a Power on Self Test (POST) error.
Fibre Channel Ports
The switch module has 4 external Fibre Channel ports through which to
connect to devices or other switches and 10 internal ports connecting to the
server midplane. Each of the external Fibre Channel ports is served by a Small
Form-Factor Pluggable (SFP) optical transceiver and is capable of 1-Gbps or
2-Gbps transmission. SFPs are hot-pluggable. External ports can self-discover
both the port type and transmission speed when connected to public devices
or other switches. The internal ports operate at 2-Gbps.
The external ports are named Ext0, Ext1, Ext2, Ext3 and are numbered 10–13
respective ports and provide port login and activity status information.

Port Logged-In LED (Green)
The Logged-in LED indicates the logged-in or initialization status of the
connected devices. After successful completion of the POST, the switch
module extinguishes all Logged-In LEDs. Following a successful loop
initialization or port login, the switch module illuminates the corresponding
logged-in LED. This shows that the port is properly connected and able to
communicate with its attached devices. The Logged-In LED remains
illuminated as long as the port is initialized or logged in. If the port
connection is broken or an error occurs that disables the port, the Logged-In
information about the Logged-In LED.
Port Activity LED (Green)
The Activity LED indicates that data is passing through the port. Each frame
that the port transmits or receives causes this LED to illuminate for 50
milliseconds. This makes it possible to observe the transmission of a single
frame. When extending credits, the Activity LED for a donor port will reflect
information about extended credits and donor ports.
Transceivers
Switch modules support SFP optical transceivers for the Fibre Channel ports.
A transceiver converts electrical signals to and from optical laser signals to
transmit and receive data. Duplex fiber optic cables plug into the transceivers
which then connect to the devices. A Fibre Channel port is capable of
transmitting at 1-Gbps or 2-Gbps; however, the transceiver must also be
capable of delivering at these rates.
The SFP transceivers are hot pluggable. This means that you can remove or
install a transceiver while the switch module is operating without harming
the switch module or the transceiver. However, communication with the
connected device will be interrupted. Refer to “Install SFP Transceivers” on
page 3-3 for information about installing and removing SFP optical
transceivers.

Ethernet Port
Port Types
Switch modules support generic ports (G_Port, GL_Port), fabric ports
(F_Port, FL_Port), and expansion ports (E_Port). Switch modules come from
the factory with all Fibre Channel ports configured as GL_Ports. Generic,
fabric, and expansion ports function as follows:
•
A GL_Port self-configures as an FL_Port when connected to a public loop
device, as an F_Port when connected to a single public device, or as an
E_Port when connected to another switch. If the device is a single device
on a loop, the GL_Port will attempt to configure first as an F_Port, then if
that fails, as an FL_Port.
•
•
A G_Port self-configures as an F_Port when connected to a single public
device, or as an E_Port when connected to another switch.
An FL_Port supports a loop of up to 126 public devices. An FL_Port can
also configure itself during the fabric login process as an F_Port when
connected to a single public device (N_Port).
•
An F_Port supports a single public device.
E_Ports enable you to expand the fabric by connecting switch modules with
other switches. Switch modules self-discover all inter-switch connections.
multiple chassis fabrics. Refer to the EFCM Basic Management Guide for
information about defining port types.
Ethernet Port
connection to a management workstation through a 10/100 Base-T Ethernet
cable. A management workstation can be a Windows® or a Linux®
workstation that is used to configure and manage the switch fabric. You can
manage the switch module over an Ethernet connection using EFCM BASIC,
the Command Line Interface (CLI), or SNMP. The switch through which the
fabric is managed is called the fabric management switch.
The Ethernet port has two LEDs: the Link Status LED (green) and the Activity
LED (green). The Link Status LED illuminates continuously when an Ethernet
connection has been established. The Activity LED illuminates when data is
being transmitted or received over the Ethernet connection.

EFCM BASIC
EFCM BASIC is a workstation-based Java® application that provides a
graphical user interface for fabric management. This includes Performance
Viewer which graphs port performance. EFCM BASIC can run on a Windows
or Linux workstation. A management workstation connects to the fabric
through the Ethernet port of one or more switch modules and can provide
in-band management for all other switches in the fabric. Refer to the EFCM
Basic Management Guide for information about the EFCM BASIC application
and its use.
McDATA Embedded Web Server
To make switch management less dependent on a particular workstation,
each switch contains a web server. One instance of the web server can be run
at a time by opening the switch IP address with an internet browser. The
switch comes from the factory with the McDATA Embedded Wed Server
enabled, but you can disable it using the EFCM BASIC application or the
command line interface. Refer to the EFCM Basic Management Guide for
information about disabling the embedded GUI service using the EFCM

Command Line Interface
The command line interface (CLI) provides monitoring and configuration
functions by which the administrator can manage the fabric and its switches.
The CLI is available over an Ethernet connection. Refer to McDATA 4314
Command Line Interface Guide for more information.
Simple Network Management Protocol
SNMP provides monitoring and trap functions for the fabric. The switch
module firmware supports SNMP versions 1 and 2, the Fibre Alliance
Management Information Base (FA-MIB) version 4.0, and the Fabric Element
Management Information Base (FE-MIB) RFC 2837. Traps can be formatted
using SNMP version 1 or 2.
File Transfer Protocol
FTP provides the command line interface for exchanging files between the
switch module and the management workstation. These files include
firmware image files, configuration files, and log files. Refer to the McDATA
4314 Command Line Interface Guide for an example of using FTP to transfer
configuration backup files.

Planning
Consider the following when planning a fabric:
•
•
•
•
•
•
•
Devices
When planning a fabric, consider the number of public devices and the
anticipated demand. This will determine the number of ports that are needed
and in turn the number of switches.
The switch module uses SFP optical transceivers, but the device host bus
adapters you are using may not. Consider whether the device adapters use
SFP or Gigabit Interface Converters (GBIC) transceivers, and choose fiber
optic cables accordingly. Use LC-type cable connectors for SFP transceivers
and SC-type cable connectors for GBIC transceivers. Also consider the
transmission speed compatibility of your devices, HBAs, switches, and SFPs.
Consider the distribution of targets and initiators. An F_Port supports a
single public device. An FL_Port can support up to 126 public devices in an
arbitrated loop.

Device Access
Device Access
Consider device access needs within the fabric. Access is controlled by the use
of zones and zone sets. Some zoning strategies include the following:
•
•
Group devices by operating system.
Separate devices that have no need to communicate with other devices in
the fabric or have classified data.
•
•
Separate devices into department, administrative, or other functional
group.
Reserve a path and its bandwidth from one port to another.
A zone is a named group of devices that can communicate with each other.
Membership in a zone can be defined by switch module domain ID and port
number, port Fibre Channel address, or by device worldwide name (WWN).
Devices can communicate only with devices within the same zone. The
switch module supports both hard and soft zones. A zone can be a member of
more than one zone set. Several zone sets can be defined for a fabric, but only
one zone set can be active at one time. The active zone set determines the
current fabric zoning.
A zoning database is maintained on each switch module consisting of all
inactive zone sets, the active zone set, all zones, aliases, and their
active zone set. Refer to the EFCM Basic Management Guide for more
information about zoning.

Soft Zones
Soft zoning divides the fabric for purposes of controlling device discovery.
Devices in the same soft zone automatically discover and communicate freely
with all other members of the same zone. The soft zone boundary is not

Device Access
secure; traffic across soft zones can occur if addressed correctly. The following
rules apply to soft zones:
•
Soft zones that include members from multiple switches need not include
the ports of the inter-switch links.
•
•
Soft zone boundaries yield to ACL zone boundaries.
Soft zones can overlap; that is, a port can be a member of more than one
soft zone.
•
•
Membership can be defined by Fibre Channel address, domain ID and
port number, or port worldwide name.
Soft zoning supports FL_Ports and F_Ports.
Access Control List Hard Zones
Access Control List (ACL) zoning divides the fabric for purposes of
controlling discovery and inbound traffic. ACL zoning is a type of hard
zoning that is hardware enforced. This type of zoning is useful for controlling
access to certain devices without totally isolating them from the fabric.
Members can communicate with each other and transmit outside the ACL
zone, but cannot receive inbound traffic from outside the zone. The following
rules apply to ACL zones:
•
•
The ACL zone boundary is secure against inbound traffic.
ACL zones can overlap; that is, a port can be a member of more than one
ACL zone.
•
ACL zones that include members from multiple switches need not
include the ports of the inter-switch links.
•
•
ACL zone boundaries supersede soft zone boundaries.
Membership can be defined only by domain ID and port number. A
switch module port can be a member of multiple ACL zones whose
combined membership does not exceed 64.

Performance
Performance
The switch module supports class 2 and class 3 Fibre Channel service with a
maximum frame size of 2148 bytes at transmission rates of 1-Gbps or 2-Gbps.
An external port adapts its transmission speed to match that of the device to
which it is connected prior to login when the connected device powers up.
Related performance characteristics include the following:
•
•
•
Distance
Consider the physical distribution of devices and switches in the fabric.
Choose SFP transceivers that are compatible with the cable type, distance,
Fibre Channel revision level, and the device host bus adapter. Refer to
Specifications for more information about cable types and transceivers.
Each Fibre Channel port is supported by a data buffer with a 16 credit
capacity; that is, 16 maximum sized frames. For fibre optic cables, this enables
full bandwidth over the following approximate distances:
•
•
26 kilometers at 1-Gbps (0.6 credits/Km)
13 kilometers at 2-Gbps (1.2 credits/Km)
Beyond these distances, however, there is some loss of efficiency because the
transmitting port must wait for an acknowledgement before sending the next
frame.
Longer distances can be spanned at full bandwidth by extending credits to
G_Ports, F_Ports, and E_Ports. Each port can donate 15 credits to a pool from
which a recipient port can borrow. The recipient port also loses a credit in the
process. For example, you can configure a recipient port to borrow 15 credits
from one donor port for a total of 30 credits (15+15=30). This will support
communication over the following approximate distances:
•
•
50 Km at 1-Gbps (30÷0.6)
25 Km at 2-Gbps (30÷1.2)
You can configure recipient and donor ports using the EFCM BASIC
application or the Set Config command. Refer to the McDATA 4314 Command
Line Interface Guide for information about the Set Config command.
Bandwidth
Bandwidth is a measure of the volume of data that can be transmitted at a
given transmission rate. A Fibre Channel port can transmit or receive at
nominal rates of 1-Gbps or 2-Gbps depending on the device to which it is
connected. This corresponds to actual bandwidth values of 106 MB and 212
MB. Multiple source ports can transmit to the same destination port if the
destination bandwidth is greater than or equal to the combined source
bandwidth. For example, two 1-Gbps source ports can transmit to one 2-Gbps
destination port. Similarly, one source port can feed multiple destination

Performance
ports if the combined destination bandwidth is greater than or equal to the
source bandwidth.
In multiple chassis fabrics, each link between chassis contributes 106 or 212
MB of bandwidth between those chassis depending on the speed of the link.
When additional bandwidth is needed between devices, increase the number
of links between the connecting switches. The switch module guarantees
in-order-delivery with any number of links between chassis.
Latency
Latency is a measure of how fast a frame travels from one port to another. The
factors that affect latency include transmission rate and the

Multiple Chassis Fabrics
Multiple Chassis Fabrics
By connecting switches together you can expand the number of available
ports for devices. Each switch in the fabric is identified by a unique domain
ID, and the fabric can automatically resolve domain ID conflicts. Because the
Fibre Channel ports are self-configuring, you can connect switches together in
a wide variety of topologies.
Optimizing Device Performance
When choosing a topology for a multiple chassis fabric, you should also
consider the locality of your server and storage devices and the performance
requirements of your application. Storage applications such as video
distribution, medical record storage/retrieval or real-time data acquisition
can have specific latency or bandwidth requirements.
The switch module provides the lowest latency of any product in its class.
the highest performance is achieved on Fibre Channel switches by keeping
traffic within a single switch instead of relying on ISLs. Therefore, for optimal
device performance, place devices on the same switch module under the
following conditions:
•
•
Heavy I/O traffic between specific server and storage devices.
Distinct speed mismatch between devices

Multiple Chassis Fabrics
Domain ID, Principal Priority, and Domain ID Lock
The following switch configuration settings affect multiple chassis fabrics:
Domain ID
Principal priority
Domain ID lock
•
•
•
The domain ID is a unique number from 1–239 that identifies each switch in a
fabric. The principal priority is a number (1–255) that determines the
principal switch which manages domain ID assignments for the fabric. The
switch with the highest principal priority (1 is high, 255 is low) becomes the
principal switch. If the principal priority is the same for all switches in a
fabric, the switch with the lowest WWN becomes the principal switch.
The domain ID lock allows (False) or prevents (True) the reassignment of the
domain ID on that switch. Switches come from the factory with the domain
ID set to 1, the domain ID lock set to False, and the principal priority set to
254. Refer to the EFCM Basic Management Guide for information about
changing the domain ID and domain ID lock using EFCM BASIC. Refer to the
Set Config command in the McDATA 4314 Command Line Interface Guide for
information about changing the default domain ID, domain ID lock, and
principal priority parameters.
An unresolved domain ID conflict means that the switch with the higher
WWN will isolate as a separate fabric, and the Logged-In LEDs on both
switches will flash green to show the affected ports. If you connect a new
switch to an existing fabric with its domain ID unlocked, and a domain ID
conflict occurs, the new switch will isolate as a separate fabric. However, you
can remedy this by resetting the new switch or taking it offline then back
online. The principal switch will reassign the domain ID and the switch will
join the fabric.
NOTE: Domain ID reassignment is not reflected in zoning that is defined by domain
ID/port number pair or Fibre Channel address. You must reconfigure zones that are
affected by domain ID reassignment. To prevent zoning definitions from becoming
invalid under these conditions, lock the domain IDs using EFCM BASIC or the Set
Config Switch command.

Switch Module Services
Switch Module Services
You can configure your switch module to suit the demands of your
environment by enabling or disabling a variety of switch services. Familiarize
yourself with the following switch services and determine which ones you
need:
•
•
•
Telnet: Provides for the management of the switch over a Telnet
connection. Disabling this service is not recommended. The default is
enabled.
Secure Shell (SSH): Provides for secure remote connections to the switch
using SSH. Your workstation must also use an SSH client. The default is
disabled.
Switch Management: Provides for out-of-band management of the
switch with EFCM BASIC, SNMP, and CIM. If this service is disabled, the
switch can only be managed inband or through the serial port. The
default is enabled.
•
•
Inband Management: Provides for the management of the switch over an
inter-switch link using EFCM BASIC, SNMP, or management server. If
you disable inband management, you can no longer communicate with
that switch by means other than a direct Ethernet or serial connection.The
default is enabled.
Secure Socket Layer (SSL): Provides for secure SSL connections for
EFCM BASIC, the McDATA Embedded Web Server, and the CIM. This
service must be enabled to authenticate users through a RADIUS server
when using EFCM BASIC. To enable secure SSL connections, you must
first synchronize the date and time on the switch and workstation.
Enabling SSL automatically creates a security certificate on the switch.
The default is enabled.
•
•
Embedded GUI: Provides for access to the McDATA Embedded Web
Server. The web server enables you to point at a switch with an internet
browser and run EFCM BASIC through the browser. The default is
enabled.
Simple Network Management Protocol (SNMP): Provides for the
management of the switch through third-party applications that use the
Simple Network Management Protocol (SNMP). Security consists of a
read community string and a write community string that serve as
passwords that control read and write access to the switch. These strings
are set at the factory to these well-known defaults and should be changed
if SNMP is to be enabled. Otherwise, you risk unwanted access to the
switch. The default is enabled.

Fabric Security
•
•
Network Time Protocol (NTP): Provides for the synchronizing of switch
and workstation dates and times with an NTP server. This helps to
prevent invalid SSL certificates and timestamp confusion in the event log.
The default is disabled.
Common Information Model (CIM): Provides for the management of the
switch through third-party applications that use CIM. The default is
enabled.
•
•
File Transfer Protocol (FTP): Provides for transferring files rapidly
between the workstation and the switch using FTP. The default is enabled.
Management Server (MS): Enables or disables the management of the
switch through third-party applications that use GS-3 Management
Server. The default is disabled.
Fabric Security
An effective security profile begins with a security policy that states the
requirements. A threat analysis is needed to define the plan of action followed
by an implementation that meets the security policy requirements. Internet
portals, such as remote access and E-mail, usually present the greatest threats.
Fabric security should also be considered in defining the security policy.
Most fabrics are located at a single site and are protected by physical security,
such as key-code locked computer rooms. For these cases, security methods
such as user passwords for equipment and zoning for controlling device
access, are satisfactory.
Fabric security is needed when security policy requirements are more
demanding: for example, when fabrics span multiple locations and
traditional physical protection is insufficient to protect the IT infrastructure.
Another benefit of fabric security is that it creates a structure that helps
prevent unintended changes to the fabric.
Fabric security consists of the following:

Fabric Security
Connection Security
Connection security provides an encrypted data path for switch management
methods. The switch supports the Secure Shell (SSH) protocol for the
command line interface and the Secure Socket Layer (SSL) protocol for
management applications such as EFCM BASIC and Common Information
Module (CIM).
The SSL handshake process between the workstation and the switch involves
the exchanging of certificates. These certificates contain the public and private
keys that define the encryption. When the SSL service is enabled, a certificate
is automatically created on the switch. The workstation validates the switch
certificate by comparing the workstation date and time to the switch
certificate creation date and time. For this reason, it is important to
synchronize the workstation and switch with the same date, time, and time
zone. The switch certificate is valid 24 hours before its creation date and 365
days after its creation date. If the certificate should become invalid, refer to
the Create command in the McDATA 4314 Command Line Interface Guide for
information about creating a certificate.
Consider your requirements for connection security: for the command line
interface (SSH), management applications such as EFCM BASIC (SSL), or
both. If SSL connection security is required, also consider using the Network
Time Protocol (NTP) to synchronize workstations and switches.

Device Security
NOTE: Device security is available only with the McDATA SANtegrity Enhanced
Product Features Enabled (PFE) key. Refer to EFCM Basic Management Guide for
information about installing a PFE key. For additional McDATA PFE keys, please
Device security provides for the authorization and authentication of devices
that you attach to a switch. You can configure a switch with a group of
devices against which the switch authorizes new attachments by devices,
other switches, or devices issuing management server commands. Device
security is configured through the use of security sets and groups. A group is
a list of device worldwide names that are authorized to attach to a switch.
There are three types of groups: one for other switches (ISL), another for
devices (port), and a third for devices issuing management server commands
(MS). A security set is a set of up to three groups with no more than one of
each group type. The security configuration is made up of all security sets on
the switch. The security database has the following limits:
•
•
•
•
Maximum number of security sets is 4.
Maximum number of groups is 16.
Maximum number of members in a group is 1000.
Maximum total number of group members is 1000.
In addition to authorization, the switch can be configured to require
authentication to validate the identity of the connecting switch, device, or
host. Authentication can be performed locally using the switch’s security
database, or remotely using a Remote Dial-In User Service (RADIUS) server
such as Microsoft® RADIUS. With a RADIUS server, the security database for
the entire fabric resides on the server. In this way, the security database can be
managed centrally, rather than on each switch module. You can configure up
to five RADIUS servers to provide failover.
You can configure the RADIUS server to authenticate just the switch module
or both the switch module and the initiator device if the device supports
authentication. When using a RADIUS server, every switch in the fabric must
have a network connection. A RADIUS server can also be configured to
authenticate user accounts as described in “User Account Security” on
page 2-12. A secure connection is required to authenticate user logins with a
information.
Consider the devices, switches, and management agents and evaluate the
need for authorization and authentication. Also consider whether the security
database is to distributed on the switches or centralized on a RADIUS server
and how many servers to configure.

Fabric Management
User Account Security
User account security consists of the administration of account names,
passwords, expiration date, and authority level. If an account has Admin
authority, all management tasks can be performed by that account in both
EFCM BASIC™ and the Telnet command line interface. Otherwise only
monitoring tasks are available. The default account name, Admin, is the only
account that can create or change account names and passwords. Account
names and passwords are always required when connecting to a switch.
Authentication of the user account and password can be performed locally
using the switch’s user account database or it can be done remotely using a
RADIUS server such as Microsoft® RADIUS. Authenticating user logins on a
RADIUS server requires a secure management connection to the switch. Refer
management connection. A RADIUS server can also be used to authenticate
Consider your management needs and determine the number of user
accounts, their authority needs, and expiration dates. Also consider the
advantages of centralizing user administration and authentication on a
RADIUS server.
NOTE: If the same user account exists on a switch and its RADIUS server, that user
can login with either password, but the authority and account expiration will always
come from the switch database.
Fabric Management
The EFCM BASIC application and CLI execute on a management workstation
that provides for the configuration, control, and maintenance of multiple
fabrics. Supported platforms include Windows and Linux. The application
can be installed and executed on the workstation, or you can run the
McDATA Embedded Web Server that is resident on the switch.
Consider how many fabrics will be managed, how many management
workstations are needed, and whether the fabrics will be managed with the
CLI, EFCM BASIC, or the web server.
A switch supports a combined maximum of 19 logins reserved as follows:
•
4 logins or sessions for internal applications such as management server
and SNMP
•
•
9 high priority Telnet sessions
6 logins or sessions for EFCM BASIC inband and out-of-band logins, and
Telnet logins. Additional logins will be refused.

Troubleshooting
Diagnostic information about the switch is available through the switch
module LEDs and the external port LEDs. Diagnostic information is also
available through the EFCM BASIC and CLI event logs and error displays.
The switch performs a series of tests as part of its power-up procedure. The
POST diagnostic program performs the following tests:
•
Checksum tests on the boot firmware in PROM and the switch firmware
in flash memory
•
•
Internal data loopback test on all ports
Access and integrity test on the ASIC
During the POST, the switch logs any errors encountered. Some POST errors
are critical, others are not. The switch uses the System Fault LED and the
Logged-In LED to indicate switch and port status. A critical error disables the
switch so that it will not operate. A non-critical error allows the switch to
operate, but disables the ports that have errors.
Input Power LED Is Extinguished
The Input Power LED illuminates to indicate that the switch logic circuitry is
receiving proper voltages. If the Input Power LED is extinguished, contact
your authorized maintenance provider.
System Fault LED is Illuminated
The System Fault LED illuminates to indicate that the switch module logic
circuitry is overheating or that a POST error has occurred. If the System Fault
LED illuminates, contact your authorized maintenance provider.

Logged-In LED Indications
Logged-In LED Indications
Port diagnostics are indicated by the Logged-In LED for each port as shown
Logged-In LED
Figure 4-1. Logged-In LED
The Logged-In LED has three indications:
•
•
•
Continuous illumination: A device is logged in to the port.
Flashing once per second: A device is logging in to the port.
Flashing twice per second: The port is down, offline, or an error has
occurred.
If a Logged-In LED is flashing twice per second, review the event browser for
alarm messages regarding the affected port. You can also inspect the alarm
log using the Show Alarm command. If there is an error, alarm messages may
point to one or more of the following conditions:
•
•
E_Port Isolation
A Logged-In LED error indication is often the result of E_Port isolation. An
isolated E_Port is indicated by a red link in the EFCM BASIC topology
display. E_Port isolation can be caused by the following:
•
•
•
•
•
Security failure
FL_Port is connected to another switch
Conflicting domain IDs
Conflicting timeout values
Conflicting zone membership between active zone sets
Refer to the EFCM Basic Management Guide for information about how to
change domain IDs, timeout values, and edit zoning.
Review the event browser and do the following to diagnose and correct an
isolated E_Port:
1. Does the event browser show an alarm about an invalid attach on the
affected port?
4-2
McDATA 4314 Fibre Channel Switch Module Installation Guide

Logged-In LED Indications
• Yes - Review the ISL group in the active security set to ensure that the
membership includes the necessary ports and that the secrets on all
switches are correct.
• No - Continue.
2. Does the event browser show a repeating alarm about an unsupported
E_Port command on the affected port?
• Yes - The port is configured as an FL_Port and connected to another
switch. Correct the port connection or the port type.
• No - Continue.
3. Display the fabric domain IDs using the Show Domains command or the
Switch data tab in the EFCM BASIC topology display. Are all domain IDs
in the fabric unique?
• Yes - Continue.
• No - Correct the domain IDs on the offending switches using the Set
Config Switch command or the EFCM BASIC Switch Properties
window. Reset the port. If the condition remains, continue.
4. Compare the RA_TOV and ED_TOV timeout values for all switches in the
fabric using the Show Config Switch command or the Switch data tab of
the EFCM BASIC topology display. Is each timeout value the same on
every switch?
• Yes - Continue.
• No - Correct the timeout values on the offending switches using the
Set Config Switch command or the EFCM BASIC Switch Properties
dialog. Reset the port. If the condition remains, continue.
5. Display the active zone set on each switch using the Zoning Active
command or the Active Zoneset tab of the EFCM BASIC topology display.
Compare the zone membership between the two active zone sets. Are
they the same?
• Yes - Contact your authorized maintenance provider.
• No - Deactivate one of the active zone sets or edit the conflicting zones
so that their membership is the same. Reset the port. If the condition
remains, contact your authorized maintenance provider.
NOTE: This can be caused by merging two fabrics whose active zone sets have two
zones with the same name, but different membership.
Excessive Port Errors
The switch can monitor a set of port errors and generates alarms based on
user-defined sample windows and thresholds. These port errors include the
following:
•
•
•
•
•
•
CRC errors
Decode errors
ISL connection count
Login errors
Logout errors
Loss-of-signal errors

Recovering a Switch Module
Port threshold alarm monitoring is disabled by default. Refer to the EFCM
Basic Management Guide for information about managing port threshold
alarms.
If the count for any of these errors exceeds the rising trigger for three
consecutive sample windows, the switch generates an alarm and disables the
affected port, changing its operational state to “down”. Port errors can be
caused by the following:
•
•
•
•
•
Triggers are too low or the sample window is too small
Faulty Fibre Channel port cable
Faulty SFP
Faulty port
Fault device or HBA
Review the event browser to determine if excessive port errors are
responsible for disabling the port. Look for a message that mentions one of
the monitored error types indicating that the port has been disabled, then do
the following:
1. Examine the alarm configuration for the associated error using the Show
Config Threshold command or the EFCM BASIC application. Refer to the
McDATA 4314 Command Line Interface Guide for information about this
command. Are the thresholds and sample window correct?
• Yes - Continue
• No - Correct the alarm configuration. If the condition remains,
continue.
2. Reset the port, then perform an external port loopback test to validate the
port and the SFP. Refer to the EFCM Basic Management Guide for
information about testing ports. Does the port pass the test?
• Yes - Continue
• No - Replace the SFP and repeat the test. If the port does not pass the
test, contact your authorized maintenance provider. Otherwise
continue.
3. Replace the Fibre Channel port cable. Is the problem corrected?
• Yes - Complete.
• No - Continue.
4. Inspect the device to which the affected port is connected and confirm
that the device and its HBA are working properly. Make repairs and
corrections as needed. If the condition remains, contact your authorized
maintenance provider.
