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
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.
Use to enable or disable a specified bridge group's ability to filter (forward or discard)
frames based on their MAC address.
Enables the bridge group to filter frames by their MAC address and add static

Specify the following:
bridgeGroupName—Alphanumeric name of the bridge group specified in the bridge
command
macAddress—Unique 48-bit (6-byte) physical address or hardware address of the
LAN network interface card as a dotted triple of four-digit hexadecimal numbers
Specify one of the following filter types:
forward—Forwards frames destined for the specified MAC address out the specified
interface
discard—Discards (drops) frames sent from or destined for the specified MAC address
without further processing
