Nexus 5010 QOS Classification

Hi

I am looking to classify the traffic on nexus 5010 form particular 2232 and want to know if there is any way with nexus we can  match traffic based on source interface or any other way I can achieve this.

Thanks

Nexus 5010 QOS Classification

Hi,

In regards to your question, you can apply a service policy directly to the FEX interface, that is, the interface where the server connects to on your Nexus 2232. Since the Nexus 2232 is just a remote line card of the Nexus 5010, all "remote" interfaces are controlled from the Nexus 5010 and appear as though they are directly attached. Only difference is that the interface number will be >100, so for example your first FEX may be registered as FEX 100. Then the first interface on this FEX will be Eth100/1/1 and this is what the Nexus 5010 will see.

You can then define your class-maps and policy-maps and then tie them together with your service-policy and apply it directly to the FEX interface.

More details around the configuration can also be reviewed by looking at your specific NX-OS version configuration guide.

Hope that helps.

Re: Nexus 5010 QOS Classification

Hi Michael,

Thanks for the reply.

my problem is  we have 2 server on to different 2232 replicating traffic between them. I need to reserve certain percentage of bandwidth for this replication.  I am having difficulty in classifying this traffic as sever gusy are not marking this traffic so I am not sure against which criteria I match this traffice. also I am assuming since 5k is just L2 acl with IP wouldn't work in this case.

I think what I am after is how do I mark particular CoS value based on Ingress interface

You can use IP address in the ACL to match, it will work.
