Stacking 9300

[RakaNRpG00]

Hello Folks,

Well, I staked 2 9300 switches then I turned on the switches, but when I connected to the switch with a console cable my terminal covered with these interface link state messages, it keeps popping up. Then I decided to remove the stacking cable but these messages stile keeping popping up. Then I did erase start up and /all nvram and these messages keeps popping up, I went to the back of the switch to reset it, also these messages keeps popping up. What should I do???

Both switches are in the same version.

what is the version of code running both, you need to follow some steps to make the stack working.

1. make sure you have uniq switch number

2. different priority.

follow below guide:

Note : your screenshot not indicated what is the problem, it is hard to ready ( post console total output in text file to read correctly)

break the stack and read the document and start over again bulding the stack
