Hi there,
We are currently building a VSS and our design has L3 subinterfaces however we have hit a major wall while trying to do the following
Below is the output showing that the option of a subinterfaces seems to be available, but it still doesn’t apply
Enter configuration commands, one per line. End with CNTL/Z.

All we can find is a little note on the release notes:
A Catalyst 4006 switch with Supervisor Engine III does not support subinterfaces or the encapsulation keyword on
Layer 3 Fast Ethernet, Gigabit Ethernet, 10-Gigabit Ethernet interfaces.
I am assuming this restriction applies to this platform but other than that there is nothing specifying we can't do this. Anyone out there has hit the same issue? or can anyone confirm this is an actual platform restriction
Thank you

Hi,
The 4500 and 4500x series switches do not support sub-interfaces. Only 6500 series support sub-interfaces.
