Use the no version to remove the static MAC address entry from the forwarding table.
See bridge address.
Use to set the length of time, in seconds, that a dynamic (learned) MAC address entry
can remain in a specified bridge group's forwarding table.
When a dynamic entry reaches its configured aging time, it "ages out" of the forwarding
table.
The default aging time is 300 seconds.
The aging-time range is 1–1000000 seconds.
Example
host1(config)#bridge westford04 aging-time 1000
Use the no version to restore the default value, 300 seconds.
See bridge aging-time.
Use to set the maximum number of dynamic (learned) MAC address entries that a
specified bridge group can learn.
For information about the maximum number of learned MAC address entries combined
for all bridge groups on an E Series router, see JunosE Release Notes, Appendix A,
System Maximums.
The default value is 0 (zero) learned addresses. This default implies that there is no
maximum number of learned entries for an individual bridge group; that is, an individual
