Hi Adam,
Update on the issues reported for LACP,
LACP QOS - Planned for July 2014.
“multicast ingress to port-channel punted to CPU” - Fixed in 15.3(3)S1 and available on Cisco.com
"BFD with ASR9K" - ASR9K BFD over Bundle feature has gone through changes in 4.3.0 or later builds and hence customers might end up seeing change in LACP behavior. Trick For running BFD over logical Bundle,
• Need to add configuration to enable at least one LC with ASR9K

Hi Waris,
This issue was discovered on 15.3(1)S2.
The “multicast ingress to port-channel punted to CPU” issue is persistent in 15.3(2)S2 as well.

Hi Adam and Darren,
Which software release you are using? EFP Link Bundling QOS is on the roadmap. I'll get back to you on the exact release.

Interesting we've had some 100% CPU until reload ourselves. It was related
to Port-channel and mcast.

On that same vein of port channels. This morning my LACP ports bounced
between my me3600x test box and a Brocade XMR and for some odd reason it
caused my LSP tunnel interfaces to push the CPU up to 99% for a few hours.
Makes me weary about using a PO at all on this box

> Can be applied to the member ports of the channel.
> Also you can't apply service policies to EFP's on a port channel either.
Thus my conclusion that port-channel interfaces on ME3600 are useless so
far
No incoming multicast
No BFD with ASR9k
No QOS
Though I'm not sure whether some of this has been fixed in the most recent
codes for X and CX
