This feature is turned on by default. In some circumstances when connecting to a third-party switch and knowing what type of cable is being used by the colour code layout, turning off polarity may help bring the ports to an active state. Please also assure that autonegotiation is turned on at both switches, or that the ports are manually configured for the same speed and duplex. the following commands can be used to verify the port information, change polarity, manually set the port speed and duplex, and to configure the medium type.<BR /> <BR /> show port # information detail<BR /> configure ports port_list auto-polarity [off| on]<BR /> configure ports auto on{[{speed speed} {duplex [half| full]}] | [{duplex[half| full]} {speed speed}]}<BR /> configure ports port_list preferred-medium[copper| fiber] {force}<BR /> <BR /> A simply test would be to temporarily loop the cable from one available port on the X430 to another, and see whether the ports become active. Do the same on the third-party switch. The cable layout is not propitiatory but the following might help to confirm the cable type: <A href="http://www.incentre.net/wp-content/uploads/2015/02/ethcable03.gif" target="_blank" rel="nofollow noreferrer noopener">http://www.incentre.net/wp-content/uploads/2015/02/ethcable03.gif</A><BR /> Wed, 09 Sep 2015 23:02:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/extreme-summit-x430-24t/m-p/49791#M13263 Ty_Izzet 2015-09-09T23:02:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/extreme-summit-x430-24t/m-p/49792#M13264 How can I readout auto-polarity status for a port via snmp?<BR /> <BR /> I've been looking in 15.4 mib and found 1.3.6.1.4.1.1916.1.24 extremeDiagPortPairAPol ( Pair A till D ) But my x670 and x440 do not have OID answer in that range.<BR /> <BR /> Any hint welcome!<BR /> <BR /> Tue, 06 Oct 2015 15:36:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/extreme-summit-x430-24t/m-p/49792#M13264 Leo_Bistmans1 2015-10-06T15:36:00Z
