juniEthernetIfDuplexMode

Module: Juniper-ETHERNET-MIB

OID (symbolic): Juniper-ETHERNET-MIB::juniEthernetIfDuplexMode

OID (numeric): 1.3.6.1.4.1.4874.2.2.34.1.1.1.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The configured duplex setting for this ethernet interface. The operational value is reported in this table entry's corresponding juniEthernetIfOperDuplexMode object.

NOTE, configuration dependency:

Setting this object to values other than 'autoDuplex' takes effect only when the corresponding juniEthernetIfSpeed object is simultaneously set to other than 'autoNegotiate'.

Otherwise (i.e. this object is set to 'autoDuplex', AND/OR corresponding juniEthernetIfSpeed object is set to 'autoNegotiate'), duplex mode is negotiated.

What is juniEthernetIfDuplexMode?

Sets the configured duplex mode for this Ethernet interface -- auto, half, or full duplex (default auto); a non-auto value only takes effect if juniEthernetIfSpeed is also set to a fixed speed, otherwise duplex is negotiated.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.34.1.1.1.1.2
snmpwalk -v2c -c public <target> Juniper-ETHERNET-MIB::juniEthernetIfDuplexMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.34.1.1.1.1.2.1
snmpget -v2c -c public <target> Juniper-ETHERNET-MIB::juniEthernetIfDuplexMode.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4874.2.2.34.1.1.1.1.2.1 i <value>
