Hi,
I have 2 x 3750 stacked, the port number of the master switch is gigabitEthernet2/0/1, slave as gigabigEtherent1/0/1.
Can I change the port numbering so that the master switch gets GigabitEthernet1/0/x?
Cheers,
Hannah

The interface number is part of the switch numbering scheme.
You could try renumbering the switches.
This will require a downtime maintainance window as
the switches need to reload
1) Renumber switch 1 to 3
config t
!
switch 1 renumber 3
end
!
reload slot 1
!
show switch
! verify switch stack is now 2 & 3
copy run start
2)config t
!
switch 2 renumber 1
end
!
reload slot 2
!
show switch
! verify switch stack is now 1 & 3
copy run start
3)config t
!
switch 3 renumber 2
end
!
reload slot 3
!
show switch
! verify switch stack is now 1 & 2
copy run start
It is also recommended that you set thye priorities
for the switches making the highest prority (15)
affective on the master switch.(Usually 1)
conf t
!
switch 1 priority 15
switch 2 priority 1
!
end
!
copy run start
I would then power off both switches
Then power on switch 1 wait 30 seconds then power on switch 2
show switch
Hopefully you should now seethe status you want
