FC Ping and FC Traceroute

FC Ping and FC traceroute are used to troubleshoot problems with connectivity and path choices. They
Note
are not designed for use in identifying or resolving 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 re-routed and sent back to the source. Using Ping, you
can verify connectivity and latency to a particular destination across an IP routed network. Traceroute
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. These tools have been migrated to Fibre Channel for use with the Cisco MDS
9000 Family switches and are called FC Ping and FC Traceroute. You can use FC Ping and FC
Traceroute from the CLI or from the Cisco Fabric Manager.
FC Ping allows you to ping a Fibre Channel N_Port or end device. By specifying the FC_ID or Fibre
Channel address, you can send a series of frames to a target N_Port. Once these frames reach the target
device's N_Port, they are looped back to the source and a time-stamp is taken. FC Ping helps you to
verify the connectivity and latency to an end N_Port. FC Ping uses the PRLI Extended Link Service, and
verifies the presence of a FC entity in case of positive or negative answers.
