RMON Probe Capability
The Remote Network Monitoring (RMON) probe is an instrument that
exists for the purpose of managing a network. The goals of the RMON
probe are described in the following sections: Offline Operation, Proac-
tive Monitoring, Problem Detection and Reporting, Value Added Data,
and Multiple Managers. The CenturyStack 8100 Managed Series Hubs
support RMON group (1) statistics, group (2) History, group (3) Alarm,
and group (9) Event.
•
Offline Operation: This allows a probe to be configured to
perform diagnostics and to collect statistics continuously,
even when communications with the management station
may not be possible or efficient.
•
Proactive Monitoring: The monitor can notify the manage-
ment station of failure and can store historical statistical
information about the failure. The management station can
play this historical information back in an attempt to
perform further diagnosis into the cause of the problem.
•
Problem Detection and Reporting: The monitor can be
configured to recognize conditions, most notably error
conditions, and to continuously check for them. When one
of these conditions occurs, the event may be logged, and
management stations may be notified in a number of ways.
•
•
Value Added Data: By highlighting those hosts on the
network that generate the most traffic or errors, the probe
can give the management station precisely the information
it needs to solve a class of problems.
Multiple Managers: Remote monitoring can deal with
multiple management stations using its resources
concurrently.

Redundant Link Capacity
Redundant links can be configured enabling up to 24 pairs in a
CenturyStack. For each pair of redundant links one port must be set as the
primary and active, the other as backup and isolated. If the primary port
fails, it is isolated and the backup port is set to primary and active.
Address Tracking Capability
CenturyStack provides MAC Address based tracking capability for traffic
analysis to diagnose network problems such as Intrusion. This function
records the source MAC address of each data packet received by the port
and provides the filter for data analysis. Up to 15 source MAC addresses
can be detected on each port.
Source Address Search Capability
CenturyStack provides Source Address Search Capability. This active
address tracking capability is used to watch for a given MAC address and
report on which port it was seen. This capability can be used to collect the
necessary information for mapping the topology of a network. Up to 8
MAC addresses can be searched simultaneously. You can configure
address search parameters including Source MAC address and Address
Search Status with local console management, Web-Based Management
or SNMP management.
Security Intrusion Control Capability
CenturyStack provides MAC Address based Security Intrusion Control
Capability to prevent any unauthorized nodes access to the network. You
can configure the hub to take various actions when a violation is detected.
Actions include: no action, sending a trap message or partitioning a port.
Broadcast Storm Detection and Protection Capability
CenturyStack provides Broadcast Storm Detection and Protection
Capability by periodically monitoring the broadcast counters of each port
to detect a broadcast storm. Ports detected causing a broadcast storm are
automatically partitioned, a trap is sent to the network manager, or no
action is taken, depending on the configuration.

Installation
Choosing a Location
The CenturyStack location should be less than 100 meters from servers,
workstations, or switches. The CenturyStack can be desk mounted or rack
mounted.
CAUTION: Category 5 UTP/STP cables are environmentally
sensitive. Make sure that the cable route is not too close to
electrical noise sources such as power lines or fluorescent lights.
Stacking
The CenturyStack Managed Series are stackable in standard 19” racks.
Up to six hubs can be stacked with cascade cables. One master and up to
five slaves can make up a stack. The master can be positioned anywhere
in the stack, so you can add to a stack without re-positioning the hubs.
Rack Mounting
Rack mounting brackets are included to mount hubs in a standard EIA
19-inch racks.
Align the mounting brackets on the sides of the unit with the slit over the
holes. Secure the screws tightly to fix the brackets to the device. Then,
place the device into the 19" rack and affix it properly. Please ensure that
the ventilation holes on the unit are not blocked.
Using Cascade Cables
You can stack the CenturyStack 8100 Series hubs using cascade cables.
The master hub can be placed anywhere in the stack. By cascading the
hub stack, each hub is automatically identified and assigned an ID number
according to its position in the stack.
Installation 17

Constructing a Management Hub Stack
A stack can be constructed with up to six hubs in total. One master hub
and up to five slave hubs can exist in one stack.
Position within the Stack
The master hub can be positioned anywhere in a stack and automatically
assigns the ID of each hub according to its position in the stack.
Master Hub Role
The master is used to manage and configure other hubs in the stack and
supplies the stack with additional ports (12/24) and an additional expan-
sion module slot. The master hub can also be used as a stand-alone
intelligent hub. Managing the hubs can be accomplished with the master
hub’s versatile management capabilities, such as:

Slave Hub Role
Slave hubs supply the stack with additional ports (12/24) and an addi-
tional expansion module slot. Slave hubs can be positioned above or
below the master hub. The 8112-01-S and 8124-01-S can also act as stand
alone unmanaged hubs.
Hub ID
The master hub and slave hubs can be positioned anywhere in the stack
and each hub’s ID is automatically assigned based on its position (in the
stack).
Segmenting Hubs
CenturyStack hubs can isolate one or both segments (10 Mbps and 100
Mbps segments) from the other hubs in a stack. When a segment is
isolated it does not repeat to the other segments in the hub or to other
segments in the stack.
Connecting Devices
The dual speed CenturyStack can connect to 10Mbps, 100Mbps, or
10/100Mbps devices due to its auto sensing capability. CenturyStack will
auto sense the connected port speed and set its port to match the speed of
the connected port.
Cables
CenturyStack ports accept Cat 3, 4 and 5 cables with RJ-45 connectors
for 10Mbps connections and Cat 5 cables with RJ-45 connectors for
100Mbps connections. The maximum length of cables, between hub and
workstations is 100 meters. The maximum length of cables, between hub
and hub is 5 meters for 100Mbps connections and 100 meters for

Chapter 2
Using Expansion Modules
Expansion Module Overview
Expansion modules provide additional functions such as internal bridging
of 10Mbps and 100Mbps segments and extended distances between
devices. The available modules are:
•
•
•
•
Module 8102-01-X: 2 port Bridge or 10/100BASE-TX
Switch Module
Module 8102-03-X: 2 port Bridge or 100BASE-FX
Fiber Distance Extender Switch Module
Module 8103-01-X: 3 port Bridge and 10/100BASE-TX
Switch Module
Module 8103-03-X: 2 port Bridge and 100BASE-FX
Fiber Distance Extender Switch Module
With CenturyStack, the software setting for Bridging Module Admin State
(external distance extender function and internal function) is disabled by
default. The Admin State of a bridge module must be configured using
Console or Web-Based Management after installation.
Internal Bridge Function
The Internal Bridge Function is used for bridging 10Mbps and 100Mbps
segments in a hub or in a stack. Only one internal switch can be enabled
in a CenturyStack, more than one will cause network looping.
IMPORTANT: There can only be one internal switch enabled in a
CenturyStack, however multiple external bridges are allowed. Therefore,
if more than one module exists in a CenturyStack, ensure that only one
module has its internal bridge enabled.
External Bridge Function
The external bridge function is used to extend the distance between
100Mbps hubs or stacks from the normal limitation of five meters to one
hundred meters with TX modules using RJ 45 cable. With FX modules
using fiber cable, you can expand the distance between hubs or stacks up
to 2km.
Using Expansion Modules 23
Download from Www.Somanuals.com. All Manuals Search And Download.
Backpressure (flow control)
When packets are passed from 100Mbps segments to 10Mbps segments
the flow is restricted due to the lesser capacity of the 10Mbps segment
causing backpressure and resulting in dropped packets. With flow control
or backpressure enabled, packets are made to wait until the flow is
unrestricted before being sent, reducing the number of dropped packets.
Installing a Bridge Module
Power down CenturyStack before installing a bridge module. Bridge
modules have both hardware and software configuration settings. The
hardware configurations must be made before you physically install the
module and the software configurations must be made using a master hub,
after the module is installed and before the bridging functions take effect.
Please read this section carefully before installing modules.
IMPORTANT:
•
These modules are not hot swappable. You must remove
power from the hub before installing or replacing a
bridge module.
•
You should enable the internal bridge on only one bridge
module when you have multiple bridge modules installed
in a CenturyStack. This prevents a network loop
condition.
•
Three bridge modules are shipped with the Internal
Bridge function enabled (8102-01-X, 8103-01-X and
8103-03-X), only the 8102-03-X is shipped with the
Internal Bridge function disabled. All models ship with
the backpressure function disabled.
To install these modules, perform the following steps. Use static sensitive
precautions.
1. Set the bridge function and backpressure function by moving
the appropriate jumpers. See the following sections for the
bridge module model that you are installing and set the
jumpers accordingly.

2. Remove the power from the hub by disconnecting the power
cable from the AC outlet.
3. Remove the installed bridge module or blank cover of the
expansion module slot (not the NMU slot, only the bottom
slot is available) by turning the two knobs on the front
counterclockwise as shown below.

module.
7. For stand alone slave models the installation is complete,
just connect AC power.
8. If your adding this hub to an existing stack, connect the hub
to the stack. Refer to Chapter 1: Using Cascade Cables.
9. Reconnect the AC power cord to the wall outlet.

10.For a hub stack with a master present, you must configure
the software for the installed bridge module to enable the
internal bridge function because the software default setting
is disabled. The default software setting will not allow the
internal bridge function to enable. The software must be
configured using a master hub.
11.Start a Console or Web-Based Management session and set
the software configuration for the new module. For
information on starting a console session, refer to
Chapter 4: Console Management. For information on
Bridge Module configuration, refer to Chapter 4: Console
Management: Controlling Devices.

Observing Network Traffic
You can observe the network traffic in the Mini Console with the Utiliza-
tion menu. Seven columns of gauge bars, which shift continuously from
left to right as time elapses, represent the utilization rate of each segment.
The gauge bar columns on the left are for the 10Mbps segment and the
gauge bars on the right are for the 100Mbps segment. Each column of
gauge bars is a historical view of the total utilization in the 10Mbps
segment and the total utilization in the 100Mbps segment at the time the
statistics were taken by the hub. The total utilization history, represented
by the seven columns in each segment is over a three-second time frame.
“UTILIZATION” and “10M 100M” display in the Message Zone
interchangeably at intervals of several seconds as shown below.

Configuring Ports
The PORT CONFIG menu enables you to configure individual ports or all
ports at one time. You are prompted to enter the password when the
console is locked. The ports must be configured to match the devices at
the other end of the link. Settings such as speed must be identical. All
ports are set to default to AUTO NEGO. When the AUTO NEGO mode is
set, the highest speed supported by both ends is negotiated by the port and
the device at the other end.

You can set up a management session by connecting a direct RS-232 cable
between the management port on the CenturyStack and the communication
port of your PC or terminal.
To connect a local terminal to the CenturyStack, do the following:
1. Install a terminal emulation application such as Windows
Hyperterminal on your PC.
2. Configure the terminal emulation application as follows:
Baud rate ....... 9600
Parity .............. None
Data bits ......... 8
Stop bits ......... 1
Flow Control ... None
VT-100 ........... Configuration
3. If you are using Microsoft Windows terminal emulation,
disable the “Use Function, Arrow, and Ctrl Keys for Windows”
option in the Terminal Preferences menu under Settings.
4. Connect the console management port on the CenturyStack
to your PC or DTE device using a serial cable. The
CenturyStack has a 9-pin, female connector.

it to restore internal bridge operation.
NOTES:1. These modules are not “hot-swappable”.
You must remove power from the hub before installing
or removing the modules. 2. You should enable the internal
bridge on only one switch module if you have multiple
bridge modules installed in the stack. This prevents a
network loop condition.

Redundant Link Control
The Redundant Link Control menu allows configuring up to 24 pairs of
redundant links. A redundant pair consists of any two physically linked
ports in the stack, where one is the primary link port and the other is the
secondary link port. The primary link is the active link between two
devices and the secondary is a backup and is set to inactive to prevent
looping. In the event that the primary link fails, the secondary link
becomes active. The secondary link stays active even if the primary link
recovers. You must manually reset the primary link status to active in
order to re-instate the redundant pair.
Redundant Link Control
You configure a primary link by assigning a specific port on a specific
hub to a Link Pair Index. You assign a secondary link by assigning a
specific port on a specific hub to the same Link Pair Index.
Link Pair Index: The number identifying the redundant link
pair. (1 to 24)
Primary Link Group: This object identifies the hub ID of the
primary link for a given redundant link pair.

Disable: No trap is sent to the trap receivers if a switch
over occurs.
Status: You can enable, disable or suspend the operation of
specific redundant link pairs.
•
Enable: The redundant link pair is in the normal operation
mode.The primary port is active and the secondary port is
disabled.
•
Disable: If you disable the active port, the status of this
link pair is changed to the suspend state and indicates that
the active port has been disabled and the redundant link
function is temporarily suspended. If you enable the active
port later on, the status of this redundant link pair is changed
to enabled.
NOTE: Setting the redundant link to disable does not cause
the ports to be switched over.

been partitioned to check if the broadcast storm condition still exists. The
partitioned hub port is auto recovered to normal operation once the
broadcast storm condition is released.

Troubleshooting the Network
Q: The local-console ‘login screen’ does not come up sometimes when a
terminal (PC running terminal emulation) is connected to already
booted master hub. Why?
A: The screen must be refreshed, when CenturyStack is running and the
terminal emulator is started. Pressing Ctrl + R refreshes the screen
and the login menu appears.
Q: Users of the 100Mbps segment cannot use Web-Based Management,
however 10Mbps segment users can. Why?
A: The SNMP agent, TCP/IP stack and the Web engine are implemented
on the 10Mbps bus of the master hub. Therefore the 10Mbps
segment must be used for Web-Based Management in the absence
of a switch module.
Q: Even though the switch module with internal bridging has been
installed, the 10Mbps segments can’t communicate with the
100Mbps segments. Why?
A: The switching function is disabled by default in the software, there-
fore even though the internal function is enabled with the on board
jumpers, 10Mbps and 100Mbps segments cannot communicate. The
internal switch must be enabled using local console management
through connections from the RS-232 port on the hub to a serial port
on a PC. Select Device Control from the main menu and then 2/3 port
bridge module control/status. Enable the internal switch.
Q: With regards to CenturyStack modules: Users will need to use Web
or Console management to enable the module, however, what if users
only have a slave model in their LAN and want to install a 8102-01 as
an internal switch or have a 8103-01 as both internal and external, or
have another slave model in the stack and one 8102-01 as an external
switching port?
A: In the case of 8112-01-S only, (whether single or multiple stacked),
the switch module will function straightaway when installed. The
mode (“internal” or/and “external”) can be set on the module PCB
using the jumpers provided. When the master hub is present, we need
to additionally enable the module’s function in the management
software (through Local Console or Web-Based Management/SNMP
Management).

Q: Is there a loop detection and isolation feature available in
CenturyStack, in case two switch modules (internal bridging enabled
on the hardware) are installed in the same stack?
A: No. The stack will go into a loop even before the software has booted.
Therefore, the only control is on hardware (jumpers on the PC board)
Q: In Web-Based Management, the Hub’s front panel is not displayed.
A: For Netscape users, you need to clear the memory cache. To clear
memory cache, from the Netscape menu bar, select Edit, select
Preferences from the drop down list, click the + sign beside Advanced
and then select Clear Memory Cache.
Q: I do not see the graphic of the unit when I use Internet Explorer
as my browser.
A: If you are using Internet Explorer version 4.72 or newer, you will
need to modify the Java settings. From the task bar, select View,
then Internet Options, then Security. Set security to Custom, then go
into Settings. From here, scroll down to Java and click Custom. A
Java Custom Settings box displays in the lower left corner. Select this
box, highlight Permission Given to Unsigned Content, then select the
Edit Permission tab. Finally, select Enable under Run Unsigned
Content.
