I want to configure LLQ on my Router which has 2 FE interface.
I want only application always gets min 5990 Bandwidth in either case.
and one user get 8 kbps.
I configure the router with below mention command but still not able to get the desired result. both users are able to get bandwidth in MB and no LLQ is working.
version 12.4

I think you didnot apply the created policy to interface fa0/0 using command service-policy.

any update ???

Is this still an issue?
if so you are performing LLQ on an FE interface. LLQ will work when the interface is congested. The FW is not congested - and adding a bandwidth statement will NOT change the interface speed which will still be 100mbs.
What you need to do is not congestion management - you need to police and traffic shape!
