4 Priority Commands - port - Port number. (Range: 1-26/50) • port-channel channel-id (Range: 1-32) Default Setting The mapping for all interfaces is displayed. Command Mode Privileged Exec Example This shows that traffic entering Port 1 that matches the specifications for protocol group 1 will be mapped to VLAN 2: Console#show interfaces protocol-vlan protocol-group Port ProtocolGroup ID Vlan ID ---------- ------------------ ----------Eth 1/1 1 vlan2 Console# Priority Commands The commands described in this section allow you to specify which data packets have greater precedence when traffic is buffered in the switch due to congestion. This switch supports CoS with four priority queues for each port. Data packets in a port’s high-priority queue will be transmitted before those in the lower-priority queues. You can set the default priority for each interface, the relative weight of each queue, and the mapping of frame priority tags to the switch’s priority queues. Table 4-60 Priority Commands Command Groups Function Page Priority (Layer 2) Configures default priority for untagged frames, sets queue weights, and maps class of service tags to hardware queues 4-183 Priority (Layer 3 and 4) Maps IP DSCP tags to class of service values 4-189 Priority Commands (Layer 2) Table 4-61 Priority Commands (Layer 2) Command Function Mode Page queue mode Sets the queue mode to strict priority or Weighted Round-Robin (WRR) GC 4-184 switchport priority default Sets a port priority for incoming untagged frames IC 4-184 queue bandwidth Assigns round-robin weights to the priority queues GC 4-185 queue cos map Assigns class-of-service values to the priority queues IC 4-186 show queue mode Shows the current queue mode PE 4-187 show queue bandwidth Shows round-robin weights assigned to the priority queues PE 4-188 4-183
