Configuring Optional Bridge Group Attributes
After you create a bridge group, you can configure the following optional attributes
for the bridge group to manage the MAC address entries in the bridge group’s
forwarding table:
■
Enable or disable the bridge group’s ability to acquire dynamically learned MAC
addresses; acquiring dynamic MAC addresses is enabled by default.
host1(config)# bridge westford01 acquire
■
Enable or disable the bridge group’s ability to filter (forward or discard) frames
with a particular MAC source or destination address.
host1(config)# bridge westford01 address 0090.1a40.4c7c forward atm 3/0.1
host1(config)# bridge westford02 address 1011.22c2.333d discard
■
Set the aging time of a dynamic (learned) entry in the forwarding table.
host1(config)# bridge westford01 aging-time 200
■
Set the maximum number of dynamic MAC addresses that a bridge group can
learn.
host1(config)# bridge westford02 learn 10000
You can also optionally enable SNMP link status processing for the bridge group. For
example:
host1(config)# bridge westford03 snmp-trap link-status
bridge acquire
■
Use to enable or disable a specified bridge group’s ability to acquire dynamically
learned MAC addresses; acquiring dynamic MAC addresses is enabled by default.
■
Enables the bridge group to forward any frames it receives for nodes (stations)
whose address it has learned dynamically.
■
Example
host1(config)# bridge westford01 acquire
■
Use the no version to prevent the bridge group from acquiring dynamically
learned MAC addresses and to limit forwarding only to those nodes that have a
statically configured address entry in the forwarding table.
■
See bridge acquire.
