Description

Issue the specified Fibre Channel ELS request to the specified peer port ID via the specified Fibre Channel port. The request must be one of the following:

flogi - Log in to Fibre Channel fabric
plogi - Log in to Fibre Channel port
prli-fcp - Log in to FCP initiator or target
logo - Log out
echo - Ping

If no port is explicitly specified, iPXE will use the first Fibre Channel port as shown by fcstat

If no peer port ID is explicitly specified, iPXE will attempt to use a sensible default port ID as follows:

if the port is attached to a fabric via a Fibre Channel switch, iPXE will use the well-known port ID ff.ff.fe,

if the port is attached directly to another Fibre Channel peer, iPXE will use the ID of the peer port.

Command status

Success	The ELS request received a successful response
Failure	The ELS request did not receive a successful response

Build options

This command is available only when the build options NET_PROTO_FCOE and FCMGMT_CMD are enabled.

Notes

You can use the fcstat command to view the state of Fibre Channel ports and peers.

Fibre Channel ELS requests are generally issued automatically as needed. You should only need to use the fcels command if you need to debug Fibre Channel problems.
