Priority Commands (Layer 2)

Class of Service 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 eight priority queues for each port. Data packets in a
port's high-priority queue will be transmitted before those in the lower-priority
queues. The default priority can be set for each interface, also the queue service
mode and the mapping of frame priority tags to the switch's priority queues can be
configured.

show interfaces switchport
show queue mode
show queue weight
Function
Configures the queue mode, queue weights, and default priority for
untagged frames
Sets the default priority processing method (CoS or DSCP), maps
priority tags for internal processing, maps values from internal priority
table to CoS values used in tagged egress packets for Layer 2 interfaces,
maps internal per hop behavior to hardware queues
Function
Sets the queue mode to Weighted Round-Robin (WRR),
strict priority, or a combination of strict and weighted
queuing
Assigns round-robin weights to the priority queues
Sets a port priority for incoming untagged frames
Displays the administrative and operational status of an
