slSonetApsChanStatus

Module: SL-SONET-APS-MIB

OID (symbolic): SL-SONET-APS-MIB::slSonetApsChanStatus

OID (numeric): 1.3.6.1.4.1.4515.1.6.5.1.1.1.12

Node type: OBJECT-TYPE

Type: Bits

Access: read-only

Description: Indicates the current state of the port.

lockedOut This bit, when applied to a working channel, indicates that the channel is prevented from switching to the protection line. When applied to the null channel, this bit indicates that no working channel may switch to the protection line.

sdWorking A signal degrade condition on the working line is in effect.

sdProtecting A signal degrade condition on the protecting line is in effect.

sfWorking A signal failure condition on the working line is in effect.

sfProtecting A signal failure condition on the protecting line is in effect.

switched The switched bit is applied to a working channel if that channel is currently switched to the protection line.

remoteRequest The switch request was initiated by the remote NE.

What is slSonetApsChanStatus?

A read-only bitmask reporting the current APS channel state: lockedOut, sdWorking/sdProtecting (signal degrade on working/protection line), sfWorking/sfProtecting (signal failure on working/protection line), switched (working channel currently on protection line), and remoteRequest (switch initiated by the far end). An admin reads this bitmap to diagnose exactly why and how a line pair is currently switched.
