Understanding output of : ucsm-B(nxos)# sh int br

Hi All ,

Could you please help me understand the output of the following command :

ucsm-B(nxos)# sh int br

I have a few queries on the interfaces number eth1/1/1 to eth 1/1/8 :

What governs the naming convetion used for the ethernet ports starting eth1/1/1 to eth1/1/9 ?

If I connect another chassis to the FI , will it start by eth2/1/1 ?

I would like to understand how Eth1/x/x or Eth2/x/x is decided by the UCS for naming ..

Hello Vikas,

These are host interfaces ( HIF ) / backplane ports on the FEX / IOM connecting to the blades.

Eth//

" show fex detail " would provide additional information about FEX ports.

The ninth interface provides CIMC connectivity to the blades,
