ddmStatusLossSignal
Module: TPLINK-DDMSTATUS-MIB
OID (symbolic): TPLINK-DDMSTATUS-MIB::ddmStatusLossSignal
OID (numeric): 1.3.6.1.4.1.11863.6.96.1.7.1.1.8
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-only
Description: This object indicates whether local SFP reports signal loss or not.
What is ddmStatusLossSignal?
This read-only string indicates whether the local SFP transceiver in this port is reporting a loss-of-signal condition. Admins check it as a direct indicator of a broken optical link on the local end, whether from a disconnected fiber, a failed far-end transmitter, or excessive attenuation. Seeing signal loss reported here on a port that should be up would prompt an admin to check the fiber connection and the far-end device.
