Port-Channel Sub-interfaces on ISRs

[Steven Williams]

I seem to be having issues finding my answer and I do not have a physical unit around to test, but do the 2900 series ISRs support Layer 3 Port-Channel sub-interfaces? I know they won't do LACP so has to be configured Static on.

Thank you! I wasn't sure. I have done it on an ASR plenty of times, but different platform.

no problem ye it varies from platform to platform seen in on 65s before but not the 45s so wasn't sure either until I checked
