foreSonetPathDiagnosticsC2

Module: Fore-Sonet-Ext-MIB

OID (symbolic): Fore-Sonet-Ext-MIB::foreSonetPathDiagnosticsC2

OID (numeric): 1.3.6.1.4.1.326.2.2.1.1.14.4.4.1.1

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Controls the insertion of Signal label/Payload Defect Indication (PDI_P) into the C2 byte of the Sonet path overhead. The various values for Signal label/PDI_P are defined in GR-253-CORE.

off When set to off, the C2 byte is set to previously configured C2 value. on When set to on, the foreSonetPathDiagnosticsC2Value is inserted in the C2 byte of the tranmsit stream.

What is foreSonetPathDiagnosticsC2?

A test-mode control for the path's C2 signal-label byte: off (default) transmits the previously configured C2 value normally, on forces the value in foreSonetPathDiagnosticsC2Value to be inserted instead, letting an admin simulate a Payload Defect Indication or a specific signal-label value for interoperability testing.
