Honoring dot1p values on ingress packets
FTOS provides the ability to honor dot1p values on ingress packets with the Trust dot1p feature. Enable
Trust dot1p using the command
to which the classified traffic is sent based on the dot1p value.

When using QoS service policies with multiple class maps, you can configure FTOS to use the incoming
DSCP or dot1p marking as a secondary option for packet queuing in the event that no match occurs in the
class maps.
When class-maps are used, traffic is matched against each class-map sequentially from first to last. The
sequence is based on the priority of the rules, as follows:
1. rules with lowest priority, or in the absence of a priority configuration,
2. rules of the next numerically higher queue
By default, if no match occurs, the packet is queued to the default queue, Queue 0.
