ES20 - Port Queues

Unanswered Question
Sep 30th, 2009


I have a 7609 with a WS-X6748-GE-TX. When I show the port capabilities I

can see rx-(1q8t), tx-(1p3q8t)

If I show queueing on an interface I see all the WRED and WRR queue


This is great, I can make changes and view changes.

I also have an ES20 and ES20+ line card in the chassis. When I show the

port capabilities I see x-(NotDef-t), tx-(NotDef-t)

When I show queueing on an interface I see nothing for the ES20. For the

ES20+ I get

Interface GigabitEthernet1/1 queueing strategy: Weighted Round-Robin

Port QoS is enabled

Port is untrusted

Extend trust state: not trusted [COS = 0]

Default COS is 0

So the ES20 tells me nothing and the ES20+ only shows a subset of what I

see with the WS-X6748-GE-TX.

Is there something I am missing in my config to show what queues I have

available on the ES line cards '(1p3q8t)'

From reading the line card configuration guides I can see ingress

scheduling is not supported and egress is but when I configure a egress

policy-map with my random-detect configuration I still see no queueing

info for the ports.

Hi Anthony,

ES and 6748 are two completely different type of LC based on different hardware.

ES20 LC support 16K hw queues to give you an example in addition to H-QoS, shaping,..

You should use the show policy-map interface command instead.
