expressGSPortDuplexMode

Module: EXPRESSGS-MIB

OID (symbolic): EXPRESSGS-MIB::expressGSPortDuplexMode

OID (numeric): 1.3.6.1.4.1.343.6.13.3.6.3.1.1.31

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: A point-to-point Ethernet port may be configured to support half or full duplex communications.

A full-duplex(2) port transmits and receives data concurrently, effectively doubling the data rate of the port.

Half-duplex(1) ports transmit or receive data, but not at the same time. Half-duplex ports use CSMA/CD as the access method to the network. Ports that are connected to shared segments (i.e. connected to a repeater), should always be configured to be in half-duplex mode.

This object indicates the desired duplexity of this port. If auto-negotiation is turned on for this port, then this value is ignored.

What is expressGSPortDuplexMode?

Sets the desired duplex mode -- half-duplex(1) or full-duplex(2) -- for a point-to-point Ethernet port; the value is ignored if auto-negotiation is enabled for the port. An admin forces half-duplex(1) to match a legacy hub segment where full duplex would cause excessive errors.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.343.6.13.3.6.3.1.1.31
snmpwalk -v2c -c public <target> EXPRESSGS-MIB::expressGSPortDuplexMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.343.6.13.3.6.3.1.1.31.1
snmpget -v2c -c public <target> EXPRESSGS-MIB::expressGSPortDuplexMode.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.343.6.13.3.6.3.1.1.31.1 i <value>
