Configuring FC ping
Overview
In an FC SAN, use the fcping command to check whether a destination address is reachable and to test
network connectivity.
The FC ping works as follows: the source device sends an echo request to the destination device and
determines whether the destination is reachable based on whether it receives an echo reply. If the
destination is reachable, the source device determines the link quality based on the number of echo
requests sent and the number of replies received, and it determines the distance between the source and
destination based on the round-trip time of FC ping packets.
A switch supports the following FC ping operations:
• FC ping an N_Port from the switch—Use the fcping command on the switch to ping an N_Port at the
remote end. The destination address of the FC ping operation is the FC address of the N_Port.
• FC ping a switch from the current switch—The destination address is the domain controller address
FFFCxx of the destination switch, where xx is the domain ID of the destination switch.
