usdSonetMediumTimingSource
Module: Unisphere-Data-SONET-MIB
OID (symbolic): Unisphere-Data-SONET-MIB::usdSonetMediumTimingSource
OID (numeric): 1.3.6.1.4.1.4874.2.2.7.1.1.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Selects the source from which transmit timing is derived. loop(0) indicates timing is recovered from the receiver; internalModule(1) indicates timing is from the module associated with this interface; internalChassis(3) indicates timing is taken from the internal system timing reference.
What is usdSonetMediumTimingSource?
Sets where this SONET/SDH interface derives its transmit clock from: loop(0) recovers timing from the received signal, internalModule(1) uses the local module's clock, or internalChassis(2) uses the chassis-wide timing reference. Get this wrong across a network and you risk clock slips; typically only one device in a SONET ring should be the primary timing source with others set to loop or a traceable reference.
