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.
