Ingress QoS on Catalyst 3560

[Michael Muenz]

Dear Users,

I'm currently configuring per port policing on a 3560 and want to limit inbound traffic to 750mbit:

mls qos

access-list 1 permit any

class SET_IF

match access-group 1

policy-map SET_QOS

class SET_IF

   police 750000000 500000 exceed-action drop

interface Gi0/24

service-policy input SET_QOS

When I test the setup with iperf I always get different results when I change the nummber of parallel connections.

Isn't there a way to limit the throughput regardless of the number of conns (INGRESS!) like with srr-queue bandwith limit?

Thanks!

Is your iperf transport protocol setup TCP or UDP?

If it's TCP, depending on your topology, markings and configuration, the reason could be WRED.

Hey Rolf,

thanks for commenting, 3560 doesn't support WRED, I'll have a look at WTD the next days, nice hint!
