sdlcSapDuplex

Module: CXSDLC-MIB

OID (symbolic): CXSDLC-MIB::sdlcSapDuplex

OID (numeric): 1.3.6.1.4.1.495.2.1.6.37.1.1.8

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This object applies only to lower SAPs (service access points).

It determines if the SAP operates in full-duplex or half-duplex mode.

Range of Values:

fullduplex (1): The SAP operates in full duplex mode, allowing data to be transmitted is both directions at the same time (two-way simultaneous transmission). On the link, RTS is raised when DTR is raised.

halfduplex (2): The SAP operates in half duplex mode, allowing data to be transmitted in both directions, but not at the same time (two-way alternate transmission). On the link, RTS is raised during transmission and dropped during reception.

Default Value: fullduplex (1)

Configuration Changed: administrative and operative

What is sdlcSapDuplex?

This read-write value, applicable only to lower SAPs, sets full-duplex (default) or half-duplex operation, which changes how RTS is raised on the link relative to DTR/transmission. An admin sets halfduplex(2) when the attached modem or line only supports two-way alternate (not simultaneous) transmission.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.495.2.1.6.37.1.1.8
snmpwalk -v2c -c public <target> CXSDLC-MIB::sdlcSapDuplex

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.495.2.1.6.37.1.1.8.1
snmpget -v2c -c public <target> CXSDLC-MIB::sdlcSapDuplex.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.495.2.1.6.37.1.1.8.1 i <value>
