Priority Commands; Priority Commands (Layer 2); Switchport Priority Default - Accton Technology VS4512DC Management Manual

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.

switchport
switchport priority default
This command sets a priority for incoming untagged frames. Use the no form to

Syntax
switchport priority default default-priority-id
no switchport priority default
default-priority-id - The priority number for untagged ingress traffic.
The priority is a number from 0 to 7. Seven is the highest priority.
Default Setting
The priority is not set, and the default value for untagged frames received on
the interface is zero.
Configures default priority for untagged frames, sets queue weights,
and maps class of service tags to hardware queues
Maps TCP ports, IP precedence tags, or IP DSCP tags to class of
service values
Sets a port priority for incoming untagged frames
Sets the queue mode to strict priority or Weighted
Round-Robin (WRR)
Assigns round-robin weights to the priority queues
Assigns class-of-service values to the priority queues
Shows the current queue mode
Shows round-robin weights assigned to the priority queues
Shows the class-of-service map
Displays the administrative and operational status of an
interface
