NAME

       fcping - Fibre Channel Ping (ELS ECHO) tool

SYNOPSIS

       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

DESCRIPTION

       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.

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

EXAMPLES

       Sends ELS ECHO to Port FC-ID 0xbf0027 from interface n0.170 with max 3 pings.

	   fcping -c 3 -h n0.170 -F 0xbf0027
