cdx6500sdlcpLineType

Module: SDLC-OPT-MIB

OID (symbolic): SDLC-OPT-MIB::cdx6500sdlcpLineType

OID (numeric): 1.3.6.1.4.1.449.2.1.2.1.1.12.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: Type of line, indicates whether half duplex or full duplex signals are being generated. fdx - communications occuring in both directions simultaneously between devices. hdx - transmission occuring in both directions, but only one direction at a time. This operation is not currently supported. hdxdce - (Half Duplex DCE) This is used on the HPAD when the port is a DCE and the port is interfacing directly to a FEP. The port detects RTS go HIGH, waits RTS TO CTS DELAY ms, and raises CTS. newvalHdx - same functionality as 'hdx', new enumeration added for RFC1155 compatibility.

What is cdx6500sdlcpLineType?

Indicates whether the port is running full duplex (fdx), half duplex (hdx), or half-duplex DCE (hdxdce, used when the port acts as DCE facing a FEP). An admin uses this to confirm the port's duplex mode matches what the attached device expects before chasing other causes of poor throughput.
