FCPING(8) Open-FCoE Tools FCPING(8)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
