It is recommended to enable the Link Loss Alert (LLA) feature on ports that are connected
to end devices. LLA should be disabled for switch ports connected in a ring.
The Link Loss Alert feature is disabled by default on 100 MB Fiber Optic ports. It can be
enabled and disabled via the
setport port=<port#|list|range> [lla=<enable|disable>]
