Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 325)

NOTE
If an edge-port becomes an ISL port because a remote port’s VCS ID was changed, a port that
was already shutdown by ELD must be cycled with the shutdown and no shutdown
commands to be detected as an ISL port.
• To re-enable all ports disabled by ELD, enter clear edge-loop-detection.
