Vpls And Rate Limiting; Mac Move - Alcatel-Lucent 7750 SR OS Service Manual

VPLS and Rate Limiting

Traffic that is normally flooded throughout the VPLS can be rate limited on SAP ingress through
the use of service ingress QoS policies. In a service ingress QoS policy, individual queues can be
defined per forwarding class to provide shaping of broadcast traffic, MAC multicast traffic and
unknown destination MAC traffic.

MAC Move

The MAC move feature is useful to protect against undetected loops in a VPLS topology as well
as the presence of duplicate MACs in a VPLS service.
If two clients in the VPLS have the same MAC address, the VPLS will experience a high re-learn
rate for the MAC. When MAC move is enabled, the SR-Series will shut down the SAP or spoke
SDP and create an alarm event when the threshold is exceeded.
