The standby fabric card is updated with the software MAC address table during the bulk synchronization process. The standby fabric card becomes active and the software MAC address table on the new active card is used. When the EFP is not the first EFP on the bridge domain on the card, nothing needs to be done as the MAC addresses learned on the bridge domain are already present.Īll the MAC addresses learned on the port on all the bridge domains are deleted. When the EFP is the first EFP on the bridge domain on the card, all the MAC addresses learned on the bridge domain are sent to this new card.

Nothing needs to be done as the MAC addresses learned on the bridge domain are already present.Īll the MAC addresses learned on that EFP are deleted. These MAC addresses are also removed from the line card hardware.Īn EFP is added and is the first EFP on a bridge domain on a card.Īll the MAC addresses learned on the bridge domain are sent to this new card.Īn EFP is added and is not the first EFP on a bridge domain. The MAC addresses learned on the bridge domain are removed from the software MAC address table that is maintained on the fabric cards. The MAC learning is not supported in point–to–point bridge domains. The MAC learning is enabled by default in point–to–multipoint bridge domains. The following table describes the various scenarios and the actions taken on MAC addresses for each scenario. The MAC addresses are learned on the LAG interface instead of the physical interface. MAC learning is enabled on the LAG interface, if the Link Aggregation Group (LAG) interface is part of the point–to–multipoint bridge domain. When a MAC move is detected, a transient event is generated to inform the user about the MAC move. MAC MoveĪ MAC move occurs when the same MAC address is re-learned on a different port. The learned MAC addresses are distributed to the other cards with Ethernet Flow Points (EFPs) in the same bridge domain. Dynamic MAC Address Learningĭynamic MAC address learning occurs when the bridging data path encounters an ingress frame whose source address is not present in the MAC address table for the ingress service instance. The expected MAC address age out timer is between 300 to 600 seconds depending on the number of MAC addresses learned.

In CPT, the default value for MAC address aging is 300 seconds and cannot be changed. This frees up unused addresses from the MAC address table for other active subscribers. See NTP-J7 Enable or Disable MAC Learning on a Bridge Domain.ĭynamically learned MAC addresses are deleted after the MAC address age out value. Noteīy default, MAC address learning is enabled only for point–to–multipoint bridge domains and can also be disabled. This MAC address table is used to distribute the MAC addresses when the line card reboots or goes through Online Insertion and Removal (OIR). This MAC address table contains the MAC addresses learned on all the line cards. The MAC learning feature enables the distribution of the MAC addresses learned on one line card to the other line cards.Ī software MAC address table is maintained on the fabric cards. The MAC addresses learned on one line card needs to be learned or distributed on the other line cards. The Carrier Packet Transport (CPT) system is a distributed system with fabric cards, line cards, and CPT 50 panels. This chapter also describes the configuration procedures.
