QoS help!!!!

Limitless1801 · ‎09-26-2012

Hi,

I need some help with a QoS configuration I am trying to apply. I have two router R1 and R1 which are connected via Metro Ethernet. I have configured and applied the QoS configuration show below but as you can see R2 is not matching any of the traffic. The two configurations are identical. What am I doing wrong?

Thanks, RG

Shouldn't your ACL on R2 be reversed. I believe you are listing your destination IP's as your source.

Sorry. They are. I grabbed the wrong list:

10 permit ip any host 172.16.1.46

20 permit ip any host 172.16.20.51

30 permit ip any host 172.16.20.52

40 permit ip any host 172.16.20.53

50 permit ip any host 172.16.20.54

60 permit ip any host 172.16.20.55

70 permit ip any host 172.16.20.56

80 permit ip any host 172.16.20.57

90 permit ip any host 172.16.20.58

100 permit ip any host 172.16.20.59

110 permit ip any host 172.16.1.123

120 permit ip any host 172.16.1.124

Thanks, RG

Shouldn't the policy map be on your LAN interface?

Julio Tenorio · ‎09-26-2012

Looks like you need a hierarquical Qos policy.

Believe you'll want the policy applied on your subinterface. For how, see Julio's reference.

Below are the outputs for the show policy-map interface g0/1. What's confusing me is that it seems to be working on R1 but not in R2 and it's been applied in the same place. When I try to apply on the sub interface, I get the following message:

CBWFQ : Not supported on subinterfaces

I'll take a look at Julio's link and I'll post the results back.

Thanks, RG
