Monitoring and Maintaining the Transparent Bridge Network

This section describes how to monitor and maintain activity on the bridged network. You can use one or more of the following commands in privileged EXEC mode:

Command

Purpose

 

 

clear bridge bridge-group

Removes any learned entries from the forwarding database and clears

 

the transmit and receive counts for any statically configured

 

forwarding entries.

 

 

clear bridge [bridge-group]multicast

Removes multicast-group state information and clears the transmit

[router-ports groups counts]

and receive counts.

[group-address][interface-unit] [counts]

 

 

 

clear sse

Reinitializes the Silicon Switch Processor (SSP) on the Cisco 7000

 

series.

 

 

clear vlan statistics

Removes VLAN statistics from any statically or system configured

 

entries.

 

 

show bridge [bridge-group] [interface]

Displays details of the bridge group.

 

 

show bridge [bridge-group] [interface]

Displays classes of entries in the bridge forwarding database.

[address [mask]] [verbose]

 

 

 

show bridge [bridge-group]circuit-group

Displays the interfaces configured in each circuit group and show

[circuit-group][src-mac-address]

whether they are participating in load distribution.

[dst-mac-address]

 

 

 

show bridge [bridge-group]multicast

Displays transparent bridging multicast state information.

[router-ports groups] [group-address]

 

 

 

show bridge group [verbose]

Displays information about configured bridge groups.

 

 

show bridge vlan

Displays IEEE 802.10 transparently bridged VLAN configuration.

 

 

show interfaces crb

Displays the configuration for each interface that has been configured

 

for routing or bridging.

 

 

show interfaces [interface] irb

Displays the protocols that can be routed or bridged for the specified

 

interface.

 

 

show span

Displays the spanning-tree topology known to the router, including

 

whether or not filtering is in effect.

 

 

show sse summary

Displays a summary of SSP statistics.

 

 

show subscriber-policy policy

Displays the details of the subscriber policy.

 

 

show vlans

Displays a summary of VLAN subinterfaces.
