available for LEC association. When the LEC Fail Over field value is set to Enabled,
the LEC(s) associated with a failed physical port is automatically assigned to the
remaining operational physical port. If the failed physical port recovers, the LEC(s)
will be automatically assigned to the desired port.

the address of the LECS.
