3.5.2.1 Network Ingress Queuing for BMU Traffic
At network ingress, broadcast, multicast, and unknown (BMU) traffic identified using
DSCP and/or EXP (also known as LSP TC) is mapped to a forwarding class (FC).
Since BMU traffic is considered to be multipoint traffic, the queue hosting BMU traffic
must be configured with the multipoint keyword. Queues 9 through 16 support
multipoint traffic (see Table 11). For any adapter card hosting any number of network
ports, up to 16 queues can be configured to host 8 unicast and 8 multicast queues.
Similar to unicast queues, BMU queues require configuration of:
• queue depth (committed and maximum)
• scheduled rate (committed and peak)
In addition, as is the case for unicast queues, all other queue-based congestion
management techniques apply to multipoint queues.
