Switch port rate limit

Hi All,

I need some help with a problem I want to limit the bandwidth going to remote site on the switch connecting to our netapp.

We have a 4 port channel group setup on our 3750x switch going to our netapp storage.

We have a Wan 100mb link to our remote site and we want only 60MBs of that link to be used for Netapp traffic all other local traffic needs to use the full amount of the bandwidth to the netapp.

Is possible to allocate bandwidth in this way and how would I go about this?

We dont have access to the routers for the link and they plug directly into a port on our cisco.

Thanks

Cheers

Matt

Hello Matt,

you can use policing as follows

access-list 100 permit tcp any any eq


class-map match-all NETAP
match access-group 100


policy-map Net_AP_POLICY
class NETAP
police 60000000 conform-action transmit exceed-action drop


interface < Interface connected to SP>
service-policy output Net_AP_POLICY

Hope this helps

Harish.

On a 3750x, you can use egress queue (srr-queue bandwidth shape) shaping to limit one of 4 queues to 60 Mbps.  Of course, you'll need to insure only your Netapp traffic is directed to that queue, other traffic could go to any of the other queues.
