4 Command Line Interface 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.
