The SmartSwitch supports two modes of switch operation. The switching  
modes are as follows:  
802.1D Switching (traditional switching)  
802.1Q Switching (802.1Q port based VLANs)  
SecureFast VLAN (Cabletron Systems SecureFast switching). A  
separate image is required for this operation.  
which screens are supported in each of the available switching  
modes.  
NOTE  
the Local Management screens differs as shown in Figure 1-1 and  
Figure 1-2. Refer to the appropriate figure that relates to the Operational  
Mode set for the device to see the applicable Local Management screen  
hierarchy.  
The areas that changed in the hierarchy are highlighted as  
shown in Figure 1-1 and Figure 1-2. The screens involved are  
NOTE  
covered in this document. These screens may have been  
added or revised, or changed location in the hierarchy.

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

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

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  
A switch supporting 802.1Q VLANs provides the VLAN Configuration  
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).

Used to view which ports are included in the VLAN’s Forwarding List  
and whether to include a Tag Header in a frame being transmitted. Refer  
to your SmartSwitch device user’s guide for additional information.  
PROTOCOL VLAN CONFIGURATION  
Used to assign VLAN IDs to protocol types of received frames and to  
access the Protocol Ports Configuration screen to add or delete  
transmitting ports associated with a specific VLAN ID and protocol type.  
Refer to your SmartSwitch device user’s guide for additional information.  
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.  
Local Management Supplement

Chapter 1: Changes to Local Management Screens  
IGMP is enabled or disabled by VLAN, not port by port.  
Certain versions of firmware will not allow the switch to be a  
NOTE  
querier. Please check your release notes for further  
information. Refer to RFC 2236, Section 8, for more  
information on IGMP.  
The following multicast routing protocols are transparently supported and  
are used only to detect the location of the routers (see the Release Notes  
for any changes or additions to this list):

The following describes each field of the IGMP/VLAN Configuration  
screen:  
IGMP Version (Toggle)  
Displays the current configured IGMP version running on the VLAN  
selected in the VLAN ID field (version 1 or 2). The default is version 2.  
The IGMP Version field can be toggled to configure the switch in either  
version 1 or 2 to match the router configuration. For IGMP to function  
correctly, all switches on a LAN must be configured to run the same  
version of IGMP.  
Query Interval (Modifiable)  
If the switch is the querier, the value in the Query Interval field indicates  
how often IGMP Host-Query frames are transmitted on the VLAN  
selected in the VLAN ID field. This value is also used in calculations for  
other timers. The default value is 125 seconds. The range of possible  
entries is 1 to 300 seconds. An entry outside of the range will cause the  
error message “PERMISSIBLE RANGE: 1...300” to display in the Event  
Message field.

Query Response Time (Modifiable)  
Used to enter the maximum query response time advertised in IGMPv2  
general queries on this VLAN. This value is used in calculations for other  
timers. The default value is 10 seconds. The range of possible entries is 1  
to 300 seconds. The value entered in this field cannot be bigger than the  
Query Interval.  
Interface Robustness (Modifiable)  
Allows tuning for the expected frame loss on a subnet. If a subnet is  
expected to be high loss, the Robustness Variable may be increased.  
IGMP is robust to (Robustness Variable-1) packet losses. This value is  
used in calculations for other timers. The default value is 2.  
If the Interface Robustness is adjusted higher than the default  
value, depending on the network, this may be an indication of  
problems with the network that need to be resolved.  
TIP  
Last Member Query Interval (Modifiable)  
Displays the Max Response Time inserted into Group-Specific Queries  
sent in response to the Leave Group messages, and is also the amount of  
time between Group-Specific Query messages. This value may be tuned  
to modify the leave latency of the network. A reduced value results in  
reduced time to detect the loss of the last member of a group. The interval  
is in tenths of seconds. This value is not used if the switch is not the  
querier.  
Querier Address (Read-Only)  
Displays the address of the IGMP Querier on the IP subnet to which this  
VLAN is attached.

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.

Chapter 1: Changes to Local Management Screens  
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 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)

Security State (Selectable)  
Used to select the security state of each repeater port on the connector for  
frames received. 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.  
The last source address detected is displayed in the address column.  
This provides a quick and easy way to see what address belongs to  
what port.  
2-6  
Local Management Supplement  
 
           
Port Level Security Configuration Screen  
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.

MODULE LEVEL SECURITY CONFIGURATION  
The Module Level Security Configuration screen, Figure 3-3, is used to  
set the state of security according to connector. All repeater ports on a  
connector can be set to receive all frames (NonSecure state), lock on the  
source address of the next frame received (LockOnNext) or the source  
address of the last frame received (LockedOnAddr). When either of the  
last two options are set, the switch can be set to enable or disable the  
reception of frames and send or not send traps when an intruder is  
detected.  
To access the Module Level Security Configuration screen, use the arrow  
keys to highlight the MODULE LEVEL SECURITY  
CONFIGURATION menu item on the Repeater Configuration Menu

Security State (Selectable)  
Used to set all ports on an interface connector to the same security state.  
PortMismatch is a Read-Only field that indicates not all ports on the  
interface connector are 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.  
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.

Module Level Security Configuration  
LockedOnAddr – The Security State of all ports on the specified  
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 repeater port level, the port will  
default 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. If an address is configured or received, 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 the port locks on address and a frame is  
received that violates 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/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.

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.  
Local Management Supplement  
4-1  
 
           
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  
receives this frame, examines the frame, and extracts the VLAN IDs.  
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  
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  
 
           
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.

Local Management Supplement  
 
 
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
