of the segment without requiring user setup. However, Local
configuring that port.
NOTE
If an FE-100TX is installed, the field steps to Auto-Negotiation,
10Base-T, 10Base-TFD (full duplex), 100Base-TX, and 100Base-TXFD
(full duplex). In normal operation, the port with an FE-100TX installed is
capable of auto-negotiating the operational mode and no further user
setup is required. Section 1.9.3 describes how to manually configure an
FE-100TX.
In Auto-Negotiation, the FE-100TX negotiates to the highest common
denominator of the two interfaces. The order of priority of negotiation is
100BASE-TXFD, 100BASE-TX, 10BASE-TFD, and 10BASE-T.
Advertised Ability (Selectable)
During auto-negotiation, the FE-100TX “tells” the device at the other end
of the segment about its capabilities. The capabilities of a port with an
FE-100TX installed are 10Base-T, 10Base-TFD (full duplex mode),
100Base-TX and 100Base-TXFD (full duplex mode). In normal
operation, with all capabilities enabled, the FE-100TX “advertises” that it
has the ability to operate in any mode. The Network Manager (or user)
may choose to set up the port so that only a portion of the available
capabilities are advertised and the others are disabled. For example, only
100Base-TX and 100Base-TXFD might be enabled so that only devices
that operate at 100 Mbps can communicate with that port. Section 1.9.5
describes how to enable or disable advertised modes.

Port Redirect Configuration Screen
1.11 PORT REDIRECT CONFIGURATION SCREEN
The Port Redirect Configuration screen, Figure 1-12, enables the user to
redirect frames from one source port to one destination port. Frames
received on the source port can be redirected and transmitted in the frame
format in which they are received (normal), or they can be redirected with
a VLAN Tag (TAGGED) or without a VLAN Tag (UNTAGGED). Also,
any errored frames received can be either dropped or forwarded to the
destination port. For example, port 1 can be set as the source port with
port 2 as the destination port. Frames from port 1 are then automatically
redirected to port 2 according to the configured frame format, and frames
with errors can be either forwarded or dropped according to the screen
settings.
If an optional ATM interface is installed, up to 128 ports may be
set to redirect frames. This includes ATM Port Virtual Channels
NOTE
(PVCs).
The port redirect function is very useful for troubleshooting purposes, as
it allows traffic to be sent to a particular port where, with the use of an
analyzer or RMON probe, all current traffic from the source port can be
examined.
Although all traffic from the source port (including, if desired,
errored frames) is sent to the destination port, normal switching
NOTE
is still performed for all frames on the source port.

example, VLAN ID 1 can be set as the source VLAN with port 2 as the
destination port. Traffic from VLAN 1 is then automatically redirected to
port 2 according to the Frame Format setting for that source VLAN. The
Frame Format setting determines the format in which the frames received
belonging to the source VLAN are redirected to the destination port. The
frames can be forwarded in the frame format as received, tagged, or
untagged.
The VLAN redirect function is very useful for troubleshooting purposes.
It allows traffic associated with a particular VLAN to be sent to a
particular port where, with the use of an analyzer or RMON probe, all
current traffic from the source VLAN can be examined.
Although traffic associated with a particular VLAN is sent to the

1.17 SUMMARY OF VLAN LOCAL MANAGEMENT
The VLAN configuration process is an extension of normal Local
Management operations. A series of Local Management screens provides
access to the functions and commands necessary to add, change, or delete
VLANs and to assign ports to those VLANs. The IGMP/VLAN
Configuration screen has been added to the SmartSwitch device to enable
screens as a standard part of its Local Management hierarchy when the
switch is configured to operate in 802.1Q Mode. The hierarchy of the
Local Management screens pertaining to 802.1Q VLAN configuration is
shown in Figure 1-17. This supplement shows the revised hierarchy
(Figure 1-17) and 802.1Q VLAN Configuration Menu screen
(Figure 1-18), and describes how to use the IGMP/VLAN Configuration
screen (Figure 1-19). For information concerning the other VLAN
screens, refer to the 802.1Q VLAN User’s Guide (P/N 9032599-02).

IGMP/VLAN CONFIGURATION
Used to enable or disable IGMP (Internet Group Management Protocol)
on selected VLANs. For details, refer to Section 1.19.
1.19 IGMP/VLAN CONFIGURATION SCREEN
The IGMP/VLAN Configuration screen, Figure 1-19, is used to enable or
disable IGMP (Internet Group Management Protocol, RFC 2236) on
selected VLANs.
IGMP provides a solution for handling multicast streams in layer 2
switching devices. IGMP is for hosts on multi-access networks to inform
locally attached switches of their Multicast group membership
information. This is performed by hosts multicasting IGMP Host
Membership Reports. Multicast switches listen for these messages and
then pass them to the routers. This allows distribution trees to be formed
to deliver multicast datagrams.
Information from the IGMP packets is used to send the multicast stream
only to the end stations that request it.

1.22 ADVANCED PORT PRIORITY CONFIGURATION
SCREEN
The Advanced Port Priority Configuration screen, Figure 1-22, is used to
set the Priority/Queue Mapping and Priority Regeneration for a particular
port or change the default port priority. Priority/Queue Mapping is used to
set the transmit (TX) queue (0 or 1, with 0 being the lowest level TX
queue) for each frame priority.
For example, if the TX queue is set to 1 for those frames with a priority 1,
then those frames would be transmitted before any frames with a priority
that has the TX queue set to 0.
Priority Regeneration is used to classify different types of traffic by
reprioritizing received frames to a different transmit priority. For
example, the frames associated with a particular type of traffic that have a
received (RX) transmit priority, or a port default priority, of 3 could be
changed to have a transmit priority of 5.

TX Priority (Selectable)
Enables the frames with a certain RX priority to be changed to transmit
according to a different TX priority (0 through 7).
The following describes how the frames of learned traffic are handled.
When a frame is received, it is checked to see if it has a priority. If it does,
it is forwarded to the appropriate output port. If it does not, the frame is
assigned the default RX priority and then forwarded to the appropriate
output port. At the output port, the RX priority of the frame is checked
against the TX Regeneration table and may be transmitted at a different
TX priority according to the table. For example, all frames with an RX
priority of 3 could be regenerated with a TX priority of 5. The new value
would also be inserted in the VLAN tag if the frame is tagged as
outbound.
The regenerated priority is used to determine the correct queue as defined
in the Priority/Queue Mapping. The default values for the TX Priority
settings are listed in Table 1-3 according to RX priority.

Indicates the interface connector (ENET 1 through 4) selected in the
Interface field.
Security State (Selectable)
Used to set all ports on an interface connector to the same security state.
PortMismatch displays for an interface connector when all the ports on
the interface connector are not set to the same state. The selectable states
are as follows:
•
NonSecure – Allows the ports on the connector to receive all frames.
The source address of received frames is not examined and the frames
are processed in a non-secure state.
•
LockedOnAddr – The Security State of all ports on the specified
interface connector are set to LockedOnAddr. This setting is for
convenience, so that all ports on an interface connector can be set to
LockedOnAddr at one time. Until the address is set at the port level,
the port defaults to the locked on address of “00-00-00-00-00-00” as
indicated by “XX-XX-XX-XX-XX-XX” in the address field shown in
the Port Level Security Screen, see Figure 2-3.

The port will lock down on the address that is currently configured in
the Port Level Security Configuration screen (if one is entered), or on
the source address of the last received frame. When a port is locked on
an address, the device executes the actions selected in the Action On
Intruder field (Port Level Security Configuration screen) when a frame
is received that violates security.
•
LockOnNext – The next frame received by each port on the interface
connector is examined to learn its source address. After the source
address of a frame is learned on a port, it is now locked on that address
and only those frames received with that same source address are
allowed on that port. All frames received that do not have that same
source address will cause the device to execute the actions selected in
the Action On Intruder field.
Action On Intruder (Toggle)
Used to select the actions taken for the selected security state. There are
two fields in which to select the actions. Both toggle to activate or
deactivate the action.

•
•
LockOnNext – The next frame received by each port is examined to
learn its source address. After the source address of a frame is learned
on a port, it is now locked on that address and only those frames
received with that same source address are allowed on that port. All
frames received that do not have that same source address will cause
the device to execute the actions selected in the Action On Intruder
field.
LockedOnAddr – The port locks down on the address that is currently
configured in the Port Level Security Configuration screen (if one is
entered) or on the source address of the currently received frame. If an
address was not configured or received, the device defaults to the
locked on address of “00-00-00-00-00-00” as indicated by
“XX-XX-XX-XX-XX-XX” in the address field shown in Figure 2-3.
When a port is locked on an address and the frame received violates
the set security, the actions selected in the Action On Intruder field are
executed.
Action On Intruder (Toggle)
Used to select the actions taken for the selected security state. There are
two fields to select the actions. Both toggle to activate or deactivate the
action.
•
DisablePort/NoDisablePort– DisablePort causes the switch to turn off
the port that had a security violation. With NoDisablePort set, the port
is not turned off.
•
SendTrap/NoTrap – SendTrap causes the switch to send an SNMP trap
when a port detects a security violation. With NoTrap set, no SNMP
trap is sent.
Address (Modifiable)
Used to enter the source MAC address for the LockedOnAddr security
state setting. Once a secure address is defined on a port, only those frames
received with that same source address are allowed on that port. Any other
frame detected with a different address is considered as an intruder,
causing the actions selected in the Action On Intruder field to be executed.
When the security state setting is NonSecure, the field displays the source
address of the last frame.

Security State (Selectable)
Used to select the state of security for frames received by a specific port
on the connector. The states are as follows:
•
NonSecure – Allows the ports on the connector to receive all frames.
The source address of received frames is not examined and the frames
are processed in a non secure state.
•
LockOnNext – The next frame received by each port is examined to
learn its source address. After the source address of a frame is learned
on a port, it is now locked on that address and only those frames
received with that same source address are allowed on that port. All
frames received that do not have that same source address will cause
the device to execute the actions selected in the Action On Intruder
field.
•
LockedOnAddr – The device locks down on the address that is
currently configured in the Port Level Security Configuration screen
(if one is entered) or on the source address of the currently received
frame. If an address was not configured or received, the device defaults
to the locked on address of “00-00-00-00-00-00” as indicated by
“XX-XX-XX-XX-XX-XX” in the address field shown in Figure 3-4.

When a port is locked on an address, the device executes the actions
selected in the Action On Intruder field when a frame is received that
violates security.
Action On Intruder (Toggle)
Used to select the actions taken for the selected security state. There are
two fields to select the actions. Both toggle to activate or deactivate the
action.
•
DisablePort/NoDisable – DisablePort causes the switch to turn off the
port that had a security violation. With NoDisable set, the port is not
turned off.
•
SendTrap/NoTrap – SendTrap causes the switch to send an SNMP trap
when a port detects a security violation. With NoTrap set, no SNMP
trap is sent.
Address (Modifiable)
Used to enter the source MAC address for the LockedOnAddr security
state setting. Once a secure address is defined on a port, only those frames
received with that same source address are allowed on that port. Any other
frame detected with a different address is considered as an intruder,
causing the actions selected in the Action On Intruder field to be executed.
When the security state setting is NonSecure, the field displays the source
address of the last frame.
The Address column will display the MAC address used for the security
states, NonSecure or LockedOnAddr. This could be the last address seen
(NonSecure) or the address manually entered for the LockedOnAddr
security state.

CHAPTER 4
GENERIC ATTRIBUTE REGISTRATION
PROTOCOL (GARP)
This appendix provides the following information:
•
Describes the switch operation when its ports are configured to operate
under the Generic Attribute Registration Protocol (GARP)
applications – GARP VLAN Registration Protocol (GVRP) and/or
GARP Multicast Registration Protocol (GMRP).
•
•
Describes the GARP Configuration screen and how to use it to
enable/disable GVRP and GMRP on the switch and set each port to
operate as a GVRP- and/or GMRP-aware port.
Describes the GMRP Configuration screen and how to use it to select
individual ports, or all of the ports, and apply one of four modes of
operation according to, or regardless of, the multicast address
registration.
4.1
GARP SWITCH OPERATION
Some or all ports on the switch may be activated to operate under the
GARP applications, GVRP and/or GMRP. A description of how GVRP
and GMRP handle frames under GARP is described in Section 4.1.1 and
Section 4.2.
4.1.1
GARP VLAN Registration Protocol (GVRP)
The process of the forwarding decision and tagging frames is the same as
for 802.1Q as described in the Cabletron Systems 802.1Q VLAN User’s
Guide. However, the GVRP protocol frames will not have a tag even
when transmitted out a 1Q Trunk Port.

Chapter 4: Generic Attribute Registration Protocol (GARP)
The purpose of GVRP is to dynamically create VLANs across a switched
network. When a VLAN is declared, the information is transmitted out
GVRP configured ports on the switch in a GARP formatted frame using
the GVRP multicast MAC address (01-80-C2-00-00-21). A switch that
GVRP then creates the VLANs and adds the receiving port to its tagged
member list for the extracted VLAN ID(s). The information is then
transmitted out the other GVRP configured ports of the switch. Figure 4-1
shows an example of how VLAN blue from end station A would be
propagated across a switch network.
In Figure 4-1, Switch 4, port 1 is registered as being a member of VLAN
Blue and then declares this fact out all its ports (2 and 3) to Switch 1 and
Switch 2. These two switches register this in the Port VLAN Lists of the
ports (Switch 1, port 1 and Switch 2 Port 1) that received the frames with
the information. Switch 2, which is connected to Switch 3 and Switch 5
declares the same information to those two switches and the Port VLAN
List of each port is updated with the new information, accordingly.

GARP Multicast Registration Protocol (GMRP)
Configuring a VLAN on an 802.1Q switch creates a static GVRP entry.
The entry will always remain registered and will not time out. However,
dynamic entries will time-out and their registrations are removed from the
member list if the end station A is removed. This ensures that if switches
are disconnected, or if end stations are removed, the registered
information remains accurate.
The end result is that the Port VLAN List of a port is updated with
information about VLANs that reside off that port, even if the actual
station on the VLAN is several hops away.
4.2
GARP MULTICAST REGISTRATION PROTOCOL
(GMRP)
GMRP functions in a similar fashion as GVRP, except that GMRP
registers multicast addresses on ports. The GMRP uses the multicast
address (01-80-C2-00-00-20) for controlling the flooding of multicast
frames. End stations register with the port that they are connected to and
tell the port which multicast frames they will receive. This is
accomplished under control of GMRP, which is propagated in VLAN
context.
More Detail on Received GMRP Frames
The device is capable of supporting multiple filter databases and each
VLAN is assigned to a database. When GMRP frames are received, they
may contain a tag or be untagged.
If the GMRP frame is untagged, the multicast addresses listed in the
GMRP frame are added to the Port VLAN List of the receiving port. (For
more information about the Port VLAN List, refer to the Cabletron
Systems 802.1Q VLAN Users Guide.)
If the GMRP frame is tagged, then the VLAN ID in the tag is used to find
the filter database to which the multicast address is registered, and then
the frame is transmitted out the appropriate ports accordingly.

APPENDIX A
ABOUT IGMP
This appendix provides the following information:
•
•
•
IGMP Overview
Supported Features and Functions
Detecting Multicast Routers
To configure the SmartSwitch device for IGMP operation, refer to
Section 1.19 for instructions.
A.1 IGMP OVERVIEW
IGMP is a multicast protocol used by routers. This protocol is supported
by Cabletron Systems SmartSwitches when operating in the 802.1Q mode
to “snoop” the IGMP frames. The multicast information is gleaned from
the IGMP frame and a filter is created to send the stream of data only to
those end stations that request to receive it.
IGMP queries are sent periodically from routers. An end station that will
receive a multicast stream will send a “query response” back to the router.
If the router does not receive any response from the end station, it stops
forwarding the multicast streams to that station.
IGMP messages use an IP protocol number of 2. Routers send queries to
the all-hosts group of 224.0.0.1. End stations send query responses to the
multicast address of the stream they are requesting to receive.
Routers need to be discovered and all multicast packets need to be sent to
all routers.
A.2 SUPPORTED FEATURES AND FUNCTIONS
The following lists the features and functions supported when using
IGMP:
•
•
Runs only when the switch is operating in the 802.1Q mode.
Supports multiple multicast and non-multicast routers on the same
VLAN.
Local Management Supplement
A-1
Download from Www.Somanuals.com. All Manuals Search And Download.
Appendix A: About IGMP
•
•
Supports stand alone multicast servers only if a router is present on the
network.
Multicast forwarding rate is dependent on the number of ports to
which the multicast stream is forwarded. More ports degrade the
performance.
•
•
Supports IGMP version 1 and 2 only. Default is version 2.
Ports that are directly connected to routers are discovered dynamically
through snooping for routing protocols.
•
•
IGMP is enabled or disabled per VLAN, and not per port.
IGMP will run with GMRP, however, the IGMP does have higher
priority than GMRP.
•
•
The switch does not act as the querier. A router is required for IGMP
on the switch to function.
The switch will “snoop” on all incoming multicast addresses to detect
query responses, as well as queries. Query responses are sent to the
multicast address detected in the stream from the host requesting to
receive queries. The frame is an IP frame of protocol type 2. If the
frame is a response frame, IGMP will take the multicast address and
VLAN ID, and program a filter on the receive port. The response is
then forwarded out upstream ports so that the router will receive it.
Ports that receive queries are marked as upstream ports. It is assumed
a router exists somewhere off this port, and responses are sent here. If
the switch detects a router protocol on a port, that port is also marked
as a router port. This keeps the switch from blocking traffic to other
routers.
A.3 DETECTING MULTICAST ROUTERS
The location of a router needs to be known in order to forward IGMP
report frames back to the router. The router(s) send multicast routing
protocol frames, which get flooded throughout the network. By snooping
on the protocols, the switch will mark ports as connected to a router. The
port is put in a “forward all” mode where all multicast frames will be
flooded. This allows all types of IP multicast traffic (including IGMP
streams) to go to the router.

Detecting Multicast Routers
There are many multicast routing protocols that the switch supports.
These include the following:
•
•
•
•
PIM version 1 and 2
CBT (core based trees)
MOSPF
DVMRP
The routing protocols are detected as follows:
•
All the multicast routing protocols have a destination address of
01-00-5E.
•
DVMRP and PIM version 1 run over IGMP. If the IGMP frame type is
not a REPORT, QUERY, OR LEAVE, then the frame is assumed to be
one of these.
•

PIM version 2 is IP protocol type 0x67.
OSPF is IP protocol type 0x59. To detect that the frame is a multicast
OSPF (MOSPF), the OSPF data must be looked at. The data starts
after the IP header. Byte 31 (options) needs to be checked. If bit 2 is
set (0x02 the MC bit), the frame is a MOSPF frame.

CBT is IP protocol type 0x07.
IGMP frames are detected by checking the IP protocol type. If the type
is -x02, it is IGMP. The first byte following the IP header is the IGMP
frame type and version. (Note that the lower 4 bits of the first byte in
the IP header is the length of the IP header in 32 bit words.) The
version is always 1, so the entire byte (version +type) may be used to
check the IGMP type as follows:

0x11 = query
0x12 = report version 1
0x16 = report version 2
0x17 = leave
