Configuring FC ping
Overview
In an FC SAN, use the fcping command to identify whether a destination address is reachable and to test
network connectivity.
In an FC ping operation, the source device sends echo requests to the destination device. It determines
whether the destination is reachable based on whether it receives echo replies. If the destination is
reachable, the source device can perform the following operations:
• Determine the link quality based on the number of echo requests sent and the number of replies
received.
• Determine 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 destination switch's
domain controller address FFFCxx (xx is the domain ID of the destination switch).
