3HE 11011 AAAC TQZZA Edition: 01
The no form of this command returns the maximum FDB table size to the default (512).
Default no fdb-table-size
Parameters table-size — the maximum number of learned MAC entries in the FDB for the ring
Values 4 to 512
mac-pinning
Syntax [no] mac-pinning port port-id
Context config>card>mda>ring
Description This command keeps MAC address information that has been learned from a source frame
in the FDB until the expiry of the mac-aging timer, which is specified using the remote-age
command). If a MAC address is pinned and a frame with an existing source MAC address is
received from the other ring port, the FDB entry is not altered—the address that was learned
from the first source frame is preserved until the expiry of the aging timer. If the aging timer
is disabled, then the MAC address remains pinned until the timer is enabled again.
The no form of this command disables mac-pinning.
Default no mac-pinning
Parameters port-id — specifies the physical ring port
remote-age
Syntax remote-age aging-timer
no remote-age
Context config>card>mda>ring
Description This command specifies the aging time for remotely learned MAC addresses in the FDB.
As is the case for a Layer 2 switch, learned MAC addresses can be aged out if no packets
are sourced from the MAC address for a period of time (the aging time). The remote-age
timer specifies the aging time for remotely learned MAC addresses.
The no form of this command returns the remote aging timer to the default value (900 s).
Default no remote-age
Parameters aging-timer — the aging time for remote MAC addresses, expressed in seconds
Values 60 to 86400
