NAMEfcping − Fibre Channel Ping (ELS ECHO) tool
SYNOPSISfcping [−fqx] [ −i interval ] [ −c count ] [ −s size ] −h source target source = interface | MAC | WWPN | FC−ID target = −P WWPN | −N WWPN | −F FC−ID
DESCRIPTIONThe 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.
OPTIONS−f Flood ping −q Quiet! just print summary −x Hex dump of responses −i interval Wait interval seconds between each ping −c count Stop after sending count pings −h source Source is interface like ethX, MAC address, WWPN, or FC−ID −s size Byte−length of ping request payload (max 2108) −F FC−ID Destination port ID −P WWPN Destination world−wide port name −N WWNN Destination world−wide node name
