What is cdx6500dot3DuplexMode?

Sets whether this LAN port runs half(0) or full(1) duplex; a mismatch with the connected device's duplex setting is a classic cause of excessive collisions or CRC errors.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.449.2.1.2.1.1.8.1.9
snmpwalk -v2c -c public <target> ETH-OPT-MIB::cdx6500dot3DuplexMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.449.2.1.2.1.1.8.1.9.1
snmpget -v2c -c public <target> ETH-OPT-MIB::cdx6500dot3DuplexMode.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.449.2.1.2.1.1.8.1.9.1 i <value>
