Hello Kumaran,

here is the link

check your current cabling using the pictures and be aware that you may need to add some commands if the switches were used as stand-alone

Hope to help

Hi Kumaran,

1.Stack port is showng down.It menans that stack cable is problem or not?

Ans. ensure the cable is secure at both end or use another (new) stacking cable. use "Show switch stack-ports" command and if stack connections are good, it should show you "Ok" under the Port1/2 status accordingly

2.One Stack cable is used for connection between two switches

Is it OK?

Ans. That should be fine for 2 switches to connect.

3.Priorit also changed still both are showing master and its not coming.

Ans. This indicate, the Stack cable is faulty or connecter is not tight/screwed properly. If the stack cable is good and secure then you should only have 1 Master Switch in the stack. Having said this if both master switches are up and you try to fix the Stack Cable, you will notice one of them will instantly re-load if it detects the good Stack-Link.Follow the link which Giuseppe has sent.

use command " Show Switch Stack-ring speed" to see the status, if you have 1 Stack cable, it will show 16G and if you have 2 Stack Cables making a full ring, it will show 32G speed.

Hope This Help !!!!!
