Stack issue on Cisco 3750

Hi team,


I have an issue with the stack basing on Cisco 3750 switches.


Today on one of them, something went wrong and all ports are down.


Could you please advise, what happened? In what direction I should work to find root cause?


thank you

Hi,You can use the renumber

Hi,

You can use the renumber command:

example:
switch 5 renumber 6

switch 3 renumber 5

switch 6 renumber 5

Don't remember exactly, but you may have to reload the stack for the change to take effect.

Hi,

Separate that switch from the stack and test is individually. Look for crash files on the flash card. Also, if the product is under warranty, open a TAC ticket and have them take a look at the hardware and software..

Hi,I have found out what is

Hi,
I have found out what is the root cause.
In stack, I have 4 switches:
1. Member
2. Master
3. Member
4. Member
But right now I have next picture
1. Member - status "Ready"
2. Master - status "Ready"
3. Member - status "Provisioned"
4. Member - status "Ready"
5. Member - status "Ready"
I have checked MAC addresses, I have noticed, that member 3, became member 5.
For resolving this issue, I just need make member 5 member 3, but I don't know how to do it exactly.
My plan is:
- remove member 3.
- change number of the member 5 to member 3
Is it correct?
Thank you,
Igor
