fcping - Fibre Channel Ping (ELS ECHO) tool

       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.

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

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

           sending echo to 0xBF0027

           3 frames sent, 3 received 0 errors, 0.000% loss, avg. rt time 10.009 ms

       Sends ELS ECHO to WWNN 0x1000001B213C9DDA from interface n0.170 with max 3 pings and  payload  size  1500
       bytes

           fcping -c 3 -h n0.170 -s 1500 -N 0x1000001B213C9DDA

           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
