DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide When an interface is in the trust CoS state, the CoS of the arriving packet will be applied to the packet as the internal CoS and used to determine the CoS queue. The CoS queue is determined based on the CoS to Queue mapping table. When a packet arrives at an 802.1Q VLAN tunnel port, the packet will be added with an outer VLAN tag in order to transmit through the VLAN tunnel. If the port is to trust CoS, then the inner tag CoS will be the internal CoS of the packet and the CoS value in the packet's outer VLAN tag. If the MLS QoS CoS override is configured, then the CoS specified by command mls qos cos will be the internal CoS of the packet and the CoS value in the packet's outer VLAN tag. If the port is to trust DSCP, then the CoS mapped from the DSCP code point will be the internal CoS of the packet and the CoS value in the packet's outer VLAN tag Example This example shows how to configure port 1 to trust the DSCP mode. Switch# configure terminal Switch(config)# interface eth1/0/1 Switch(config-if)# mls qos trust dscp Switch(config-if)# 51-10 policy-map This command is used to enter the Policy-map Configuration Mode, and create or modify a policy map that can be attached to one or more interfaces as a service policy. Use the no form of this command to delete a policy map. policy-map NAME no policy-map NAME Parameters NAME Specifies the name of the policy map. The name can be a maximum of 32 alphanumeric characters. Default None. Command Mode Global Configuration Mode. Usage Guideline Use this command to enter the Policy-map Configuration Mode from where the user can configure or modify the policy for the traffic class. A single policy map can be attached to more than one interface concurrently. The succeeding policy-map attaches overwrite the previous one. Policy maps contain traffic classes. Traffic classes contain one or more match commands that can be used to match packets (and organize them into groups) on the basis of a protocol type or application. 382
