Hi Aman,

Short for Loss Of Signal, LOS is generally an indicator on a networking device to indicate that a network signal or connection has been lost.

If a LOS is encountered, it is an indication that the cable connected to the network device is bad, has no connection on the other end, network is improperly configured, or the network device itself is bad
