cpqNicIfPhysAdapterDuplexState
Module: CPQNIC-MIB
OID (symbolic): CPQNIC-MIB::cpqNicIfPhysAdapterDuplexState
OID (numeric): 1.3.6.1.4.1.232.18.2.3.1.1.11
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This variable describes the current duplex state of the adapter. A value of unknown indicates that the duplex state could not be determined.
What is cpqNicIfPhysAdapterDuplexState?
This read-only enumeration reports the current duplex state of the adapter as half, full, or unknown if it could not be determined. An admin checks this to confirm a NIC negotiated the expected duplex mode, since a half-duplex link on a network expecting full duplex causes severe performance degradation. For example, seeing half(2) unexpectedly on a server NIC that should be running full(3) points directly at a duplex mismatch as the cause of poor throughput.
