Reference Guide

When changing a Service-Queue configuration in a QoS policy map, all QoS rules are deleted
and re-added automatically to ensure that the order of the rules is maintained. As a result, the
Matched Packets value shown in the show qos statistics command is reset.
NOTE: On ExaScale, FTOS cannot classify IGMP packets on a Layer 2 interface using
Layer 3 policy map. The packets always take the default queue, Queue 0, and cannot be
rate-policed.
