Limiting outgoing traffic on a single l2 port on nexus 7000 1GB port

[Lim Victor]

Hi,

I am trying to limit the incoming and outgoing traffic on a l2 port to 8mbps for a ip subnet within the nexus 7000. The port is connected to my ISP router which has a bandwidth of 20mbps.

I read thru a few articles and it seems there is no way to do that. Policing won't work on a l2 Port and shaping cannot be applied on a port level. Am I right?

Any approach how I can do it? In

I have been reading thru the qos guide for nexus release v6 and have problems understanding the different queues.

Thanks.

Who provides the router?

did you try match access-group under the calss map and then use this class map in your policy map with plicing

Hi Guys,

Thanks for the reply.

My Nexus 7K is doing BGP peering with the ISP router.

I did the following

---------------------------------------------------------------------------------------

ip access-list Test_ACL

permit ip 10.0.0.1/27 any

policy_map Test_8mbps

class Test_ACL

police cir 8000000 pir 8000000 violate drop

int eth 4/2

service-policy output Test_8mbps

---------------------------------------------------------------------------------------

and i got the following error

---------------------------------------------------------------------------------------

N7K(config-if)# service-policy output Test_8mbps

ERROR:  Unable to perform the action due to incompatiblity:  Module 1, 2, 4  returned status "Egress policy on an L2 interface is not supported"

---------------------------------------------------------------------------------------

I tried using queuing

---------------------------------------------------------------------------------------

Policy-map type queuing Test-2Mbps-in

class type queuing 2q4t-in-q-default

bandwidth 2 mpbs

int eth 4/2

service-policy type queuing input Test-2Mbps-in

---------------------------------------------------------------------------------------

Doesn't seem to work.

It is still showing more than 2mbps when i do a show interface int eht 4/2. Should i be using "show policy-map interface ethernet 4/2" to confirm?
