[c-nsp] ASIC to switch port mapping

[Vincent Aniello]

So it looks like a WS-C3560E-24TD has two ASICs:

 

switch#show platform port-asic version

 

Port-Asic Version Info:

========================

ASIC-0: Version:4 DeviceType:0x30A

ASIC-1: Version:4 DeviceType:0x30A

 

Also, the "show platform pm if-numbers" command does return the ports
assigned with each ASIC, I overlooked the '0' in the port column because
I expected to see more than two ASICs.

sh platform port-asic should list your ASIC's

 

port groupings are almost always in groups, so you can work out what
ports belong to a common ASIC by dividing the amount of ports you have
by the amount of ASIC's listed, keep in mind you will probably have a
dedicated ASIC for the 2 10G uplinks.

This is on a 3650E switch.

Thanks.

What sort of card are you using?
