mls qos trust
Note When a trust policy and a hierarchical ingress policy are both configured on an ES port, the actions
specified in the service policy are processed before the trust policy is applied.
Note Cisco IOS Release 12.2(52)SE and later supports IPv6 port-based trust with the dual IPv4 and IPv6
Switch Database Management (SDM) templates. You must reload the switch with the dual IPv4 and IPv6
templates for switches running IPv6.
Examples This example shows how to configure a port to trust the IP precedence field in the inbound packet:
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# mls qos trust ip-precedence
This example shows how to specify that the Cisco IP phone connected on a port is a trusted device:
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# mls qos trust device cisco-phone
You can verify your settings by entering the show mls qos interface privileged EXEC command.
