[c-nsp] ASR1001 QoS on port-channel sub-interfaces

[CiscoNSP List]

FYI - I have had two TAC cases open on this "issue" Jan this year and July 2012 - The latest from TAC is:

"Currently, our engineering is working on aggregate port-channel QoS.
We don’t have an exact release at this time, but we can say that support will be no sooner than XE3.11,  and may be later."

> Hi all,
> 
> We have recently purchased an ASR1001 and seem to be hitting some limitations regarding QOS on sub-interfaces on port channels.
> 
> I can police on per-subscriber basis fine, handing down the policies from our radius server. I would also like to police the aggregate on the sub-interface that happens to be on a port-channel. When attempting to apply the service-policy to the sub-interface, it seems to apply fine; however when verifying the policy-map on the interface, I can see that it is in suspended mode and not applying.
> 
> When I attempt the suggested work-around of lacp fast-switchover with lacp max-bundle 1 on the port-channel, the sub-interface policy is able to successfully apply. However, we straight away lose a half our performance for standby.
> 
> In order to attempt to resolve, I have upgraded to version asr1001-universalk9.03.10.00a.S.153-3.S0a-ext.bin. This did not resolve.
> 
> This blog post by another network engineer sums up the issue perfectly, it was an over a year ago, so hoping the issue got some traction in Cisco.
