Module: Unisphere-Data-V35-MIB
OID (symbolic): Unisphere-Data-V35-MIB::usdV35IfIgnoreDcd

Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: When in X.21/V.35 DTE mode we have the capability of ignoring the DCD signal in determining whether or not an interface is up.
What is usdV35IfIgnoreDcd?
This object controls whether the X.21/V.35 interface, when in DTE mode, ignores the Data Carrier Detect signal when deciding if the link is up: ignoredNone(0), dcdIgnored(1), or linkStateIgnored(2). An admin sets this when connected equipment doesn't properly assert DCD, which would otherwise cause the interface to be incorrectly reported as down even though data can still flow. For example, setting it to dcdIgnored(1) lets the interface stay up despite a DCE device that never raises DCD.
