show ethernet auto-neg
The
show ethernet auto-neg
command displays the line speed characteristics of Ethernet
circuits that are configured with automatic line negotiation. Some Ethernet modules can
run at either 10 Mb/s or 100 Mb/s using a hardware process to detect the speed to use. Use
this command to identify the status of autonegotiation.
This command allows for the following command filters (flags) and filter arguments:
