Interface Priority commands

on a router 1600 series with incoming e0 & ser0 interfaces (up & activated), plus outgoing ser1 interface : we wish to give strict priority LLQ precedence to service all incoming trafic from ser0 interface absolute priority over e0 (ie traffic from ser0 will always be serviced immediately) :

the following commands were issued

(Globle Configuration mode) : priority-list 1 interface serial 0 HIGH

(local configuration mode) : int ser 0

priority-group 1

(Globle Configuration mode) : priority-list 2 interface serial 0 LOW

(local configuration mode) : int ethernet 0

priority-group 2

This should work as descibed in the Cisco Command Manual, however it didnt ! Is the router not functioning properly? or is something missing in the commands?


Re: Interface Priority commands

I assume that you have traffic coming in from S0 and E0 and going out through S1. Also I assume that your requirement is to prioritize the S0 traffic over the E0 traffic when it is queued out on S1. If this is the requirement then, you need to configure the following

priority-list 1 interface serial 0 high

priority-list 1 interface Ethernet 0 low

interface serial 1

priority-group 1

Let me know if I have mis-understood your requirement.
