fcping - Fibre Channel Ping (ELS ECHO) tool
fcping [-fqx] [ -i interval ] [ -c count ] [ -s size ] -h source target
source = interface | MAC | WWPN | FC-ID
target = -P WWPN | -N WWPN | -F FC-ID
The fcping command performs the Fibre Channel FC-LS-2 ECHO ELS command and displays the reply. The max payload for fcping is 2108 bytes. When no -c is given, fcping will continue until user interrupts.
Quiet! just print summary
Hex dump of responses
Wait interval seconds between each ping
Stop after sending count pings
Source is interface like ethX, MAC address, WWPN, or FC-ID
Byte-length of ping request payload (max 2108)
Destination port ID
Destination world-wide port name
Destination world-wide node name
