usdV35IfLoopback
Module: Unisphere-Data-V35-MIB
OID (symbolic): Unisphere-Data-V35-MIB::usdV35IfLoopback
OID (numeric): 1.3.6.1.4.1.4874.2.2.59.1.2.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Loopback interface is configured (or not) for X.21/V.35 interface
What is usdV35IfLoopback?
This object enables or disables loopback mode on the X.21/V.35 interface, with none(0) for normal operation and loopback(1) to loop transmitted signals back for testing. An admin sets this to loopback(1) temporarily to isolate whether a connectivity problem lies in the local interface or further out in the circuit, such as at the carrier's CSU/DSU. For example, enabling loopback(1) and confirming a local loop test succeeds would rule out a hardware fault on this end of the link.
Examples
