Hi Group,
I would like to rate limit traffic in and out of an interface on C3560.
The rate-limiting on incoming traffic is working fine using interface
command:
interface fa0/2
srr-queue bandwidth limit 20
(BTW, service-policy can not be applied to outgoing direction of an
interface).
However, rate limiting on outgoing traffic using policy map does not seem to
work. Under policy-map configuration, I tried both class-default, as well as
the one I manually created (Class ALL), but none seems to work. When I do
extended ping from R2 to R4, I still see traffic reaching about 4Mbps
although the C3560 meant to shape traffic at 2M.
Would you pls see if there's any error in my config, or any better ideas
doing rate-limiting on C3560.
Thanks,
R2 ----- SW2 ----- R4
