Using the Command Line Interface to Check Status

The Cisco Catalyst 5500 command line interface includes a series of commands that enable you to
determine if the MSR is functioning correctly or where problems have occurred. Relevant commands for
checking status include ping, traceroute, test snmp trap, and show. There are more than 100 show
commands, many of which can be used to check status. To learn how to find more information
concerning these and other commands, refer to the Command Reference Manual that came with the
Cisco Catalyst 5500 MSR.
