QOS on port-channel subinterface ASR 1002-X

[vincent.egal]

Hi,

I'm trying to configure some shaping and policing on a port-channel subinterface on my ASR1002-X IOS XE 03.09.02.S without success .

Is the feature supported on my version or does it need an other?

thanks

Hi,

Traditional QoS will not work for etherchannels. Please read to find suitable config for your case.

hi,

it's possible to achieve service-policy work applied to port-channel subinterface, however it's more like workaround than fix or solution. you can use:

1. global configuration command - port-channel load-balancing vlan-manual, but it will disable load balancing from flow-based algorithm and move all traffic to only member of port-channel interface.

2. port-channel subinterface command - encapsulation dot1q 2 primary gigabitethernet2/1/0 secondary gigabitethernet8/0/0 (encapsulation dot1Q vlan-id primary member-link secondary member-link)

also here is the link - http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/lanswitch/configuration/xe-16/lanswitch-xe-16-book/lnsw-vlan-map-gig.html

and I would be glad to know if there is available more elegant solution for this issue with flow-based load balancing.

Hi Ruslan,

Another Solution for the Suspended QOS with Port-Channel with Sub-interfaces without using the "load-balancing vlan".

you can use the Aggregate GEC QOS (which will provide Flow based Etherchannel QOS), Below is a sample Configurations:

platform qos port-channel-aggregate 1  ==> issue this command before creating Port-Channel 1

Then create the Port-channel "1" & apply the QOS under Port-channel Sub-interface..

The "Aggregate GEC QOS" Feature is supported from in XE 3.16.3 & later..

Hope this could help,

Islam

hi Islam,

thanks for your answer.

unfortunately I don't have opportunity to test this solution now, but anyway thanks, I beleive this will do the trick.

Yeah, that's it.

Thank you very much for your help
