I am considering VSS on two 6509-E switches but need to sustain PoE availability for some interfaces.
"The virtual switching system requires 67xx series switching modules.
The virtual switching system does not support classic, CEF256 or dCEF256 switching modules. In virtual switch mode, unsupported switching modules remain powered off."
If I enable VSS, the non-67xx line cards remain powered off.
Is there a solution avaiable for a fabic enabled line card supporting PoE?
it looks like that VSS is thought for servers and data centers
see the following note from data sheets
Note: PoE is not supported on Cisco Express Forwarding 720 10/100/1000 interface modules
So if VSS supports only 67xx modules and those modules don't support PoE you cannot provide POE on the VSS.
Or you move the POE devices to other POE capable switches or you stay without VSS
the reason for the missing POE on 67xx modules is that they already consume more power to connect to the sup720 switching fabric and also can be a design choice that sees POE as an edge/access layer feature and VSS can be seen at the distribution layer.
Hope to help
