sh mac address result show port v11

[Chris Kohr]

I'm attempting to track down a mac address to a port using the show mac address command.  I have done this many times but never once seen a port V11.  The switch is a 9407 Cisco IOS XE Software, Version 16.06.03.

Has anyone ever come across a port v11?

Thank you,

I think this is port connect sw in stack.
