The output from the show interfaces MgmtEth command displays the status of the management
Ethernet interface. For example, in the following output the management Ethernet interface is up.
MgmtEth0/RP1/CPU0/0 is up indicates that the interface hardware is currently active and line protocol
is up indicates that the keep a lives are successful. There are 42 input errors and 0 output errors.
RP/0/RP0/CPU0:router# show interfaces MgmtEth 0/rp1/cpu0/0
MgmtEth0/RP1/CPU0/0 is up, line protocol is up
Hardware is Management Ethernet, address is 0011.93ef.e8fe (bia 0011.93ef.e8fe
