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
