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

           3 frames sent, 3 received 0 errors, 0.000% loss, avg. rt time 8.647 ms

       Sends ELS ECHO to WWNN 0x1000001B213C9DDA from interface n0.170 continuously with  payload
       of 32 bytes and hex-dump the reply to the screen
