WS-X45-SUP6-E qos

Hi, 

 

I am planning to implement qos on WS-X4590-E with  WS-X45-SUP6-E Supervisor. IOS 12.2(50)

 

I will be marking couple of application to AF21 and also prioritize voice packets, signaling packets against the ACL.

 

Q: There are users connected on this modular chassis. I wanted to get some feed back if my configuration is correct ?

Q: The DBL feature should I enable it or remove ?

Q: on egress ports(part of port-channel) should I apply my egress policy to member ports or port-channel ?

ON USER ACCESS PORTS: 

Int range gig 1/0/x - x

service-policy input DEGENERS

 

==================================================

For uplinks 1G 2 ports (part of port-channel) - connected to other switch

==================================================

 

I am thinking to implement egress queuing.
