I would like to say thanks both of you who replied. Is there any other
solution. Can i use any other IOS. Can i use hierarchical QOS?. What is the
solution of this issue. Because we are using majority 6503 Cisco switches
on our border in our company. i can not change these switches, not in my
control. can i use queuing on 6503 interfaces.
Is there any way to prioritize voip traffic on these switches if MQC is not
possible can i do priority Queuing for voip traffic?
I would be thankful & appreciated on solutions & replies.
Thanks & Regards,
Ahsan Rasheed
