MQC on 3750 help please

Unanswered Question
Feb 8th, 2009

I have two 3750's attached together by two single mode fiber links bundled into a etherchannel and I am trying to use QOS to limit the HTTP and HTTPS traffic from 3750B to 3750A to approx 1mb/s. This is what I got so far and I can not get this to work...

I am using this extend access list to match the traffic source and what type.

Extended IP access list WEB_SOURCE

10 permit tcp 10.5.4.0 0.0.0.255 any eq www

20 permit tcp 10.5.4.0 0.0.0.255 any eq 443

30 permit tcp 10.5.5.0 0.0.0.255 any eq www

40 permit tcp 10.5.5.0 0.0.0.255 any eq 443

50 permit tcp 10.5.6.0 0.0.0.255 any eq www

60 permit tcp 10.5.6.0 0.0.0.255 any eq 443

70 permit tcp 10.5.8.0 0.0.0.255 any eq www

80 permit tcp 10.5.8.0 0.0.0.255 any eq 443

I then matched the access-list to this class-map

Class Map match-all WEB

Match access-group name WEB_SOURCE

Then I created the policy map to police the traffic to approx 1mb/s and drop anything over that.

Policy Map WEB_TRAFFIC

Class WEB

police 1000000 8000 exceed-action drop

I then tried to attach this to the port-channel but it would not let me so I attached it to both of the interfaces that are bound together in the etherchannel

interface Port-channel1

description UPLINK TO 3750B

no switchport

ip address 192.168.254.1 255.255.255.252

interface GigabitEthernet1/0/5

After testing a computer on 3750B the HTTP and HTTPS traffic is not limited at all. Does anyone have any idea what I am doing wrong??

Model number of this switch is WS-C3750G-12S-E

and IOS is Version 12.2(25)SEE2

Any help would be great!

I have this problem too.

Thanks for the input but I have tried that and that did not seem to help any. Any other suggestions?

Tried putting the service-policy on the port-channel interface?

Cheers

Thanks for the input, I tried to put it on the port-channel and this is the message I get

3750(config-if)#service-policy input WEB_TRAFFIC

QoS: policymap is supported on physical and VLAN interfaces only

Service Policy attachment failed

did you resolve this issue i have the same problem, 2 1 gig links and i want to limit replication traffic to 1.5 gig, i am presuming putting this on the physical ports in the channel group is no good as the ports are only 1 gig ?
