R2(config-if)#priority-?
priority-group

hence there is no command "priority-queue out"in Version 12.3(14)T7. for
PQ.

This is the message you are going to receive:
R2(config-if)#service-policy output check
Must remove priority-group configuration first.
R2(config-if)#

configuration test follows:
IOS version: Version 12.3(14)T7
Two routers connected via serial interface.
encapsulation ppp

CONFIGURATION #
R2#show queueing priority
Current DLCI priority queue configuration:
Current priority queue configuration:

List Queue Args
1 low default
1 high protocol http
1 medium protocol arp

applied it to interface serial s1/1
priority-group 1 //comment: you will not find any direction here. "not
relevant".

R2#show run inter s1/1
Building configuration...

Current configuration : 204 bytes
!
interface Serial1/1
 description to R3
 ip address 192.168.1.2 255.255.255.0
 ip nbar protocol-discovery
 encapsulation ppp
 serial restart-delay 0
 no dce-terminal-timing-enable
 priority-group 1
end

R2#show policy-map
  Policy Map check
    Class fahad
      Strict Priority
      Bandwidth 10 (%)

R2#show class-map
 Class Map match-any class-default (id 0)
   Match any

 Class Map match-any fahad (id 1)
   Match protocol http

Then tried to apply this to interface serial 1/1 and thus received the
message.

R2(config-if)#service-policy output check
Must remove priority-group configuration first.

The funda of Q is similar to access list, one per direction per
interface...

It's my understanding, and in case I am wrong, please do let me know..

Regards.

Subject: Catalyst output queue and the priotity queue

Hey Guys,

So i am bit confised about this and would appreciate some comments
please.

So on the 3550/3560s, I could enable priority queueing on one the 4
output queues on the port by issuing the interface configuration
command: priority-queue out

Now, if i had configured an LLQ on an MQC Policy map and had applied it
to the interface, how does the two attributes affect packets exitting
this port please?

I know its abit vague, but any information to incline my line of though
would be great....

Thanks!!

Sadiq
