gsEPortDuplexMode
Module: GIGAswitchEthernet-MIB
OID (symbolic): GIGAswitchEthernet-MIB::gsEPortDuplexMode
OID (numeric): 1.3.6.1.4.1.36.2.18.39.3.6.3.1.1.31
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 gsEPortDuplexMode?
Sets the desired duplex mode for a point-to-point Ethernet port when auto-negotiation is off; full-duplex(2) sends/receives concurrently for double the effective throughput, while half-duplex(1) uses CSMA/CD and is required for ports on a shared/repeated segment. This value is ignored entirely if auto-negotiation is enabled on the port.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.36.2.18.39.3.6.3.1.1.31 snmpwalk -v2c -c public <target> GIGAswitchEthernet-MIB::gsEPortDuplexMode
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.36.2.18.39.3.6.3.1.1.31.1 snmpget -v2c -c public <target> GIGAswitchEthernet-MIB::gsEPortDuplexMode.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.36.2.18.39.3.6.3.1.1.31.1 i <value>
