datagram are mapped to different priority levels based on DSCP priority mode; non-IP datagram with IEEE 802.1Q tag are mapped to different priority levels based on IEEE 802.1P priority mode if IEEE 802.1P Priority is enabled; the untagged non-IP datagram are mapped based on port priority mode. Syntax qos queue dscp-map { dscp-list } { tc-id } no qos queue dscp-map Parameter dscp-list -- List of DSCP value. One or several DSCP values can be typed using comma to separate. Use a hyphen to designate a range of values, for instance, 1,4-7,11 indicates choosing 1,4,5,6,7,11. The DSCP value ranges from 0 to 63. tc-id -- The priority level the packets with tag are mapped to, which ranges from tc 0 to tc 3. Command Mode Global Configuration Mode User Guidelines By default, the mapping relation between tag and the egress queue is: (0-15)-TC 0, (16-31)-TC 1, (32-47)-TC 2, (48-63)-TC 3. Example Map DSCP values 10-12 to TC 2: T1500-28PCT(config)# qos queue dscp-map 10-12 2 qos queue mode Description The qos queue mode command is used to configure the Schedule Mode. To return to the default configuration, please use no qos queue mode command. When the network is congested, the problem that many packets compete for resources must be solved, usually in the way of queue scheduling. The switch will control the forwarding sequence of the packets according to the priority queues and scheduling algorithms you set. On this switch, the priority levels are labeled as TC0, TC1... TC3.
