What is acSysEthernetFirstPortDuplexMode?

This OID shows whether the primary Ethernet port operates in full-duplex or half-duplex mode (simultaneous two-way or one-way communication). Engineers verify this setting is full-duplex to ensure maximum throughput and minimal collisions on the network connection. For example, full-duplex mode means data can be sent and received at the same time, while half-duplex would force the port to take turns.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5003.9.10.10.2.6.1.1
snmpwalk -v2c -c public <target> AC-SYSTEM-MIB::acSysEthernetFirstPortDuplexMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5003.9.10.10.2.6.1.1.1
snmpget -v2c -c public <target> AC-SYSTEM-MIB::acSysEthernetFirstPortDuplexMode.1
