FTOS#
FTOS Behavior: The C-Series fetches the per-queue packet count via class-maps. The count is the
number of packets matching the ACL entries in class-map. Every time the class-map or policy-map is
modified, the ACL entries are re-written to the Forwarding Processor, and the queue statistics are
cleared. This behavior is different from the E-Series. The E-Series fetches the packet count directly
from counters at each queue, which allows queue statistics to persist until explicitly cleared via the CLI.

Allocating Bandwidth to Multicast Queues

Allocating Bandwidth to Multicast Queues
The E-Series has 128 multicast queues per port-pipe, which are transparent, and eight unicast queues per
port. You can allocate a specific bandwidth percentage per port-pipe to multicast traffic using the
queue egress multicast bandwidth-percentage
command
• If you configure
multicast, and the remaining bandwidth is distributed based on your configuration.
• If you configure multicast bandwidth, after assigning the specified amount of bandwidth to multicast
the remaining bandwidth is distributed according to the WFQ algorithm.
• If you configure
based on your configuration for multicast then unicast (based on the remaining available bandwidth),
and the remaining bandwidth is distributed among the other queues.
