hubPortAutoPolarity
Module: XYPLEX-HUB-MIB
OID (symbolic): XYPLEX-HUB-MIB::hubPortAutoPolarity
OID (numeric): 1.3.6.1.4.1.33.9.3.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: A control for automatic determination of twisted-pair port polarity. 'disabled' locks the port into positive polarity. 'enabled' allows the hub to sense polarity and adapt accordingly. Corresponds directly to PORT POLARITY and the value labeled 'Auto Polarity:' in the PORT display.
What is hubPortAutoPolarity?
This object controls whether the hub automatically senses and adapts to the electrical polarity of a twisted-pair port's connection, or locks it into positive polarity. Admins disable it when a port needs to be forced to a known polarity, and enable it to let the hub self-correct for miswired cabling. For example, an admin troubleshooting a link that only works with a crossover cable might check whether this is set to disabled(1), forcing fixed polarity.
