After rebooting the stack the switch number got changed from number-5 to number-2

[Ali Hyder Sircle]

Hi,

After rebooting the stack the switch number got changed from number-5 to number-2. Both the switch were configured with below commands.

switch 1 provision ws-c3750x-48p
switch 5 provision ws-c3750x-48p

Even after that second switch got number-2 instead of 5. What was the reason for this to happen ? Should I bind switch number with System MAC/System SN so that number wont change after rebooting? 

Or should I give the switch number in pre-provisioned config?

Thanks,

Ali Hyder

Hi Ali,

Does your stack have switches 2,3,4? If not then your could provision switches 2,3 and 4 as some other model of 3750. Try something like:

!
no switch 2 provision
!

Disconnect the stackwise cables from the new 3750X, reboot the stack...

!
switch 2 provision ws-c3750g-12s
switch 3 provision ws-c3750g-12s
switch 4 provision ws-c3750g-12s
switch 5 provision ws-c3750x-48p
!

Now reconnect the new 3750X via the stackwise cables and power it on

This will pre-populate the running config and should ensure your 3750X-48 becomes switch 5 in the stack. You could then:

!
no switch 2 provision
no switch 3 provision
no switch 4 provision
!

...and it should survive a reboot.

cheers,

Seb.
