6500 QoS

dinesh2001 · ‎08-15-2011

Hi All,

I'm trying to figure out how I can do QoS on a 6500 and police traffic based on an IP access-list.

I want to define an access-list which specifies the traffic based on soure and destination IP addresses. I then plan to use a class map to match this access list and police the traffic in a qos policy. I was planning on applying the qos policy on a gig interface.

As the 6500 has a different architecture, compared to a normal router, can some suggest how I can do this. I'd like to do this on a:

WS-C6509-E (R7000) with a Supervisor Engine 720

Class maps and ACL can be used, that's just common qos config which is not different for the 6500.SUP720.

I have tested this recently for s72033-ipservicesk9_wan-mz.122-33.

You will find that only policing is supported, at least for egress. We did not need ingress so I did not check.

Hierarchical policies are also not supported.

The other restriction is regarding the interface; it must be operating in Layer3 mode so a gig interface will only work when it is configured as "no switchport", the other option is an SVI or vlan interface.

Hi Leo,

Thanks for your reply. I am using policy on a gig interface so it should work as I am only policing. However, I'm doing this in a hiearchical qos policy. The commands were taken without problems. Can you tell if it is actually working from the following output:

Device:# sh policy-map interface
GigabitEthernet4/3

Service-policy output: WAN_QOS

    class-map: CLASS_TRAFFIC (match-all)
      Match: access-group name TRAFFIC-ACL

Hi Dinesh,

It seems to be working.

Can you please verify the IOS version on your box?

Dear all,

I'm facing with a problem about monitor traffic for each class of service when i apply poilce on my Tengiga interface. The output command result as below:

!

My traffic have 2 type which classify to 2 class as above. I would like monitor traffic at fields bold (30 second offered ...). Pls advice me how to monitor this field on graph.

Thanks and best reagards,
