Reference Guide

• The default class-trust class map honors dot1p priorities in ingress ows and applies a 1-to-1 dot1p-to-qos-group and a 1-to-1 qos-
group-to-queue mapping. In OS10, qos-group represents a trac class used only for internal processing.
1. DCBX conguration (global)
Congure DCBX globally on a switch to enable the exchange of DCBX TLV messages with PFC, ETS, and iSCSI congurations.
OS10# configure terminal
OS10(config)# dcbx enable
2. PFC conguration (global)
PFC is enabled on trac classes with dot1p 4, 5, 6, and 7 trac. The trac classes all use the default PFC pause settings for shared buer
size and pause frames in ingress queue processing in the network-qos policy map. The pclass policy map honors (trusts) all dot1p ingress
trac. The reserved class-trust class map is congured by default. Trust does not modify ingress values in output ows.

3. PFC conguration (interface)
Apply the service policies with dot1p trust and PFC congurations to an interface.
OS10(config)# interface ethernet 1/1/53
OS10(conf-if-eth1/1/53)# no shutdown
OS10(conf-if-eth1/1/53)# service-policy input type network-qos test
OS10(conf-if-eth1/1/53)# service-policy input type qos pclass
OS10(conf-if-eth1/1/53)# priority-flow-control mode on
OS10(conf-if-eth1/1/53)# end
