Reports which duplex modes the port's hardware is capable of -- half only, full only, both, or with auto-negotiation. Admins check this before trying to force a duplex setting the port physically cannot do.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.208.39.3.3.1.8 snmpwalk -v2c -c public <target> ETH-SWITCH-MIB::portIfDuplexSupported
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.208.39.3.3.1.8.1 snmpget -v2c -c public <target> ETH-SWITCH-MIB::portIfDuplexSupported.1
