Verifying CISCO Catalyst DSCP Values
i am trying a simple test and banging my head against the wall. basically as a test i am trying to mark all http traffic as dscp ef. i realize the priority is overly high etc but basically i dont think the packets are being marked. please look at my config and let me know what i can do to verify this
!
class-map match-any WEB
match access-group 101
!
!
policy-map WEB
class WEB
set ip dscp ef

access-list 101 permit tcp any any eq www
when i do:
PSC-Switch#sh policy-map interface gi0/6
GigabitEthernet0/6
Service-policy input: WEB
Class-map: WEB (match-any)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: access-group 101
0 packets, 0 bytes

Class-map: class-default (match-any)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: any
0 packets, 0 bytes
5 minute rate 0 bps
i have read that the command is unsupported, so i am not overly concerned with the fact that the packets are zero. but when i do a:
sh mls qos int gi0/6 stat
sh mls qos int gi0/7 stat
the dscp values for ef are not incremented, even when i send web traffic to and from the port. am i checking it the wrong way or is this not working?

I noticed you have an etherchannel setup. Did you add the service policy to the port channel interface that was created as a result of the etherchannel setup?
ASKER
QoS: policymap is supported on physical, VLAN, and ES interfaces only
while that may be relevant here, this latest attempt was out of desperation. i have tried this on non port channel interfaces with the same result. i am either marking this wrong or trying to verifiy it wrong i think. it hasnt been an isolated incident.

I have run into this more than once on routers. Where I wasn't seeing the traffic that I was supposed to see in qos policies like you have. It turned out to be IOS related. If you haven't yet upgrade your IOS to the latest version for the switch. Just a thought.
ASKER
i am currently running the latest ios. i have similar class maps on the router and they are fine if i do the marking there. not sure why it doesnt mark on the switch though.
Hey I think I know what might be your problem.
You did a permit tcp any any eq www
so this is tcp any source any dest with a destination port of 80
But you specified this as an input policy map. It looks like you have ESX servers there so I am assuming that the web servers are on those ports.
So the traffic you will see coming input will be source of ESX with a SOURCE port of 80 and destination of the client with a destination port of random. You see what I mean.
You may need to make the acl tcp any eq www any if my assumptions are correct.

i tried the new acl, i even currently have access-list 101 permit ip any any
the counters still dont increment! what is so weird si that the dscp ef count is 102 still. i have no clue what the 102 packets were in the first place since i cant make that increase past 102 no matter what i do!

check this out, according to this none of the interfacs have recieved packets except for the vlan they belong to:

this is my first qos deployment, it just seems fundamentally broken =)
What model of switch is this?
ASKER
I have tried this on a 3750e and a 2960g.
ASKER
is there a debug command that will allow me to see packets with the dscp value? I have seen a lot about setting up qos but very little reg verifying it
do this:
show mls qos
qos is disabled by default on a 3750.
show mls qos
qos is disabled by default on a 3750.
ASKER
I did enable it. I will get the output for you when I am back at my desk
ASKER
ok a few things:
PSC-Switch#sh mls qos
QoS is enabled
QoS ip packet dscp rewrite is enabled
i blew away my qos config and did an autoqos voip cisco phone on the 2 ports. i have the same results here is the relevent config and output. it seems like even ciscos cookie cutter config shows the same results. can anyone verify that the commands i am running to try to show traffic work for them?

i dont understand how there are no packets or characters incomming to that switch port...
oddly enough this command looks right and does increment:

i may not have a real issue here, it may be a simple case of poor consistancy between the ios sh outputs, hoping somone has run into this before.

i blew away my qos config and did an autoqos voip cisco phone on the 2 ports. i have the same results here is the relevent config and output. it seems like even ciscos cookie cutter config shows the same results. can anyone verify that the commands i am running to try to show traffic work for them?

i made a call from phones on port 5 to 6. call goes through fine, here is what i get:

this really bothers me:

i dont understand how there are no packets or characters incomming to that switch port...
oddly enough this command looks right and does increment:

I did this same type setup last week on some 3750g switches. I had esi IP phones. I ran the auto qos and then had to remove the trust statements as that relies on cdp. My stats were showing correct. I did the same thing you did to check it because I wasn't sure if the phones were setting the qos the same way Cisco phones do. I was using the latest IOS version in an ipbase feature set. This was just last week.
ASKER
I have cisco phones 7975g. are you saying your policy map stats where correct when you did a sh policy-map int? mine def are not. any ideas?
Yes the show policy-map int command showed the packets in the correct class maps with qos.
Call TAC
ASKER
tac pointed me to this:
http://supportwiki.cisco.com/ViewWiki/index.php/Unable_to_display_QoS_information_at_the_port_level_with_the_show_policy-map_interface_command_in_Catalyst_3750_switch
still doesnt explain why my sh mls qos int are not showing all of the dscp values increasing though.

Well what does TAC say about the sho mls qos command not showing the stats incrementing?
ASKER
still waiting to get a response n that
ASKER
please close this, it is a known problem that will be fixed in the next ios release
