Description
Enabling this command will disable re-learning of MAC addresses on other SAPs within the VPLS.
The MAC address will remain attached to a given SAP for duration of its age-timer.
The age of the MAC address entry in the FIB is set by the age timer. If mac-aging is disabled on a
given VPLS service, any MAC address learned on a SAP/SDP with mac-pinning enabled will
remain in the FIB on this SAP/SDP forever. Every event that would otherwise result in re-learning
will be logged (MAC address; original-SAP; new-SAP).
Note that MAC addresses learned during DHCP address assignment (DHCP snooping enabled) are
not impacted by this command. MAC-pinning for such addresses is implicit.
Default
When a SAP or spoke SDP is part of a Residential Split Horizon Group (RSHG), MAC pinning is
activated at creation of the SAP. Otherwise, MAC pinning is not enabled by default.

Description
This command specifies the maximum number of FDB entries for both learned and static MAC
addresses for this SAP, spoke SDP or endpoint.
When the configured limit has been reached, and discard-unknown-source has been enabled for this
SAP or spoke SDP (see

The no form of the command restores the global MAC learning limitations for the SAP or spoke SDP.
