cmEthernetNetPortMDIXStatus
Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmEthernetNetPortMDIXStatus
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.7.1.68
Node type: OBJECT-TYPE
Type: CmEthernetMDIXType
Access: read-only
Description: This object provides the current MDIX status of the Ethernet Network port.
What is cmEthernetNetPortMDIXStatus?
This read-only CmEthernetMDIXType object reports the current, actual MDIX status in effect on an Ethernet Network Port's copper interface, as opposed to the configured setting. Admins compare this against the configured cmEthernetNetPortMDIXType to confirm auto-MDIX negotiation resolved to the expected crossover state, since a mismatch here can explain a copper link that won't come up. For example, when a straight-through vs. crossover cabling issue is suspected, an admin would read cmEthernetNetPortMDIXStatus to see the actual resolved MDIX state rather than assuming it matches the configuration.
