To modify the size of the MAC table, include the mac-table-size limit statement at the
[edit bridge-domains bridge-domain-name bridge-options] hierarchy level:
[edit]
bridge-domains {
bridge-domain-name {
bridge-options {
mac-table-size limit {
packet-action drop;
}
}
}
}
NOTE: The mac-table-size CLI statement is not supported on ACX5048 and
ACX5096 routers.

Configuring MAC Address Limits on a Logical Interface
You can configure a limit on the number of MAC addresses learned from a specific logical
interface. This feature allows the MAC address table space to be distributed among
different logical interfaces thereby avoiding congestion. The MAC address limit can be
applied for both VLAN and VPLS routing instances and by default the MAC limit depends
on the profile configured. You can limit MAC addresses for a bridge domain and a logical
interface at the same time.
NOTE: MAC limiting is supported only on ACX5000 Series routers.
