Hello Register_Security

When we run a command as below

" show interface ethernet1/x"

we see the selected results as shown

Link status:

  Runtime link speed/duplex/state: 1000/full/up

  Configured link speed/duplex/state: auto/auto/auto

This indicates the configuration was made for Speed, Duplex and State to be auto and on runtime they were negotiated to 1000 / full / UP respectively.

The command syntax will be the same for all interfaces such as Aggregate ethernet, subinterface , logical interfaces and so on.

Thanks for all reply, but what I want to see

How many are Mb/s running on each interface ?

when I show interface eth1/1

The result is below, I want to know "real running speed" (Mb/s) for Transmit and Received.
