Mls qos stats

[carl_townshend]

Hi

I have configured my switches to trust dscp markings coming in, is there anyway I can check how many packets that I am trusting on my interfaces, and what by what marking they have ?

cheers

Hi

Not a great way.

If you have 3750s or 3560s, you can do 'show mls qos interface x/x/x statistics' (i think, from memory) that will show you stats relating to input/output dscp. You can't see what's happening as a result of service policies etc.

If you have 6500s, there doesn't seem to be any commands I can find that give anything useful.

What is your switch model?

On 3650 and 3750 yes you can  check how many packets that I am trusting on my interfaces based on their DSCP markings.

The eaxmple below demonstrates that the interface gigabitEthernet 0/2 has received 8283 packets that has a DSCP marking of 0 for incoming queue.

cat3560#sh mls qos interface gigabitEthernet 0/2 statistics
GigabitEthernet0/2

  dscp: incoming 
-------------------------------

  0 -  4 :        8283            0            0            0            0 
  5 -  9 :           0            0            0            0            0 
10 - 14 :           0            0            0            0            0 
15 - 19 :           0            0            0            0            0 
20 - 24 :           0            0            0            0            0 
25 - 29 :           0            0            0            0            0 
30 - 34 :           0            0            0            0            0 
35 - 39 :           0            0            0            0            0 
40 - 44 :           0            0            0            0            0 
45 - 49 :           0            0            0            0            0 
50 - 54 :           0            0            0            0            0 
55 - 59 :           0            0            0            0            0 
60 - 64 :           0            0            0            0 

Hope that helps
