Command:

priority-group

Mode:

Router(config-if)#

Syntax:

priority-group list-number

no priority-group list-number

Syntax Description:

list-number

Priority list number assigned to the interface. Any number from 1 to 16.


Command Description:

To assign the specified priority list to an interface, use the priority-group interface configuration command. To remove the specified priority group assignment, use the no form of this command.

Only one list can be assigned per interface. Priority output queueing provides a mechanism to prioritize packets transmitted on an interface.

Use the show queueing priority and show interfaces commands to display the current status of the output queues.


Example:

The following example causes packets for transmission on serial interface 0 to be classified by priority list 1:

Router(config)#interface serial 0
Router(config-if)#priority-group 1
 

The following sample configuration shows how to establish queueing priorities based on the address of the serial link on a STUN connection. Note that you must use the priority-group interface configuration command to assign a priority group to an output interface.

stun peer-name 131.108.254.6
stun protocol-group 1 sdlc
!
interface serial 0
! Disable the ip address for interface serial 0:
no ip address
! Enable the interface for STUN:
encapsulation stun
!
stun group 2
stun route address 10 tcp 131.108.254.8 local-ack priority
!
! Assign priority group 1 to the input side of interface serial 0:
priority-group 1
! Assign a low priority to priority list 1 on serial link identified
! by group 2 and address A7:
priority-list 1 stun low address 2 A7
