www.dell.com | support.dell.com 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 trust dot1p from POLICY-MAP-IN mode. Table 41-6 specifies the queue to which the classified traffic is sent based on the dot1p value. Table 41-6. Default dot1p to Queue Mapping dot1p 0 1 2 3 4 5 6 7 E-Series Queue ID 2 0 1 3 4 5 6 7 C-Series Queue ID 1 0 0 1 2 2 3 3 S-Series Queue ID 1 0 0 1 2 2 3 3 The dot1p value is also honored for frames on the default VLAN; see Priority-tagged Frames on the Default VLAN. Fall Back to trust diffserve or dot1p e Fall Back to trust diffserve or dot1p is available only on platforms: 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. 866 | Quality of Service
