Re: CSCvp91168 - When configuring speed 100 and duplex full on both sides, interface wont come up
I´m hitting the same problem. We just deployed fifty 9200 switches that replaced lots of 2960´s.
2960 switches were working fine and all its interfaces were forced to duplex full and speed 100 and there was any issue.
BUT immediately after we installed this 9200´s lot of interfaces were in a shutdown state y never come up, interfaces on 9200 switches were still forced to duplex full and speed 100 as the old configuration of 2960 switches. Then we decided to reconfigure all interfaces of 9200 switches at speed auto and duplex auto and GUESS.........many interfaces started to come up but they were coming up at HALF duplex.
In our environment we have some AVAYA ip phones and other devices that after this new 9200 installation they came up at half duplex and that is why we do some tuning(WORKAROUND) on some interfaces of the 9200 switch in order to force some interfaces to come up at duplex full and speed 100. This type of tuning consist on disble cdp on the interface and then applied lldp transmit comand on the interface.
One more thing please remember to clear configuration on AVAYA phones( press Mute then 2723825327#) and then restart the avaya phone if it is necessary:
We have 9200-24T switch and IOS XE version is 16.11.1
