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.
