Using Cisco MDS 9000 Family Tools
FC Ping and FC Traceroute
Note
Use the Fibre Channel ping and Fibre Channel traceroute features to troubleshoot problems with
connectivity and path choices. Do not use them to identify or resolve performance issues.
Ping and traceroute
are two
of the most useful tools for troubleshooting TCP/IP networking problems.
The ping utility generates a series of
echo
packets to a destination across a TCP/IP internetwork. When
the echo packets arrive at the destination, they are rerouted and sent back to the source. Using ping, you
can verify connectivity to a particular destination across an IP routed network.
The traceroute utility operates in a similar fashion, but can also determine the specific path that a frame
takes to its destination on a hop-by-hop basis.
