You can check the port speed on a
Cisco network switch from its
command-line
interface (CLI) by logging into the switch and then issuing the
show interface command. If you want to see the parameters,
including port speed, for all ports on the switch, the command
without any additional command line arguments will display information
for all the ports on the switch. If you are only interested in the rate for
a particular port, then specify it after the command. E.g., show
interface fa0/1.
