PORT MIRRORING AND SETUP CHAPTER 9: PORT MIRRORING AND SETUP

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

lla parameter in the setport command as follows:

setport port=<port#|list|range> [lla=<enable|disable>]

The following example illustrates how to enable the link loss alert feature.
