Issue with a 3750XPOE after copying configuration

dcgtechnologies
Level 1
Level 1

I copied the configuration from my 3750G to my new 3750X on GigabitEthernet1/0/1-48, which is the exact configuration on my 3750G and I had a hard time trying to figure out why it would not work, but after some long time troubleshooting I found out that I have two sets of Gigabitethernet Interfaces on this switch. They are GigabitEthernet1/0/1-48 and GigabitEthernet3/0/1-48. I had to configure GigabitEthernet3/0/1 in order to get everything to work. Do you know why this is like this on this switch? How do I use GigabitEthernet1/0/1 and delete GigabitEthernet3/0/1? I did notice it does have a stack member number of 3 and I am not using the stack configuration. Does this have something to do with it? Thank you for all your help.

I did the re-number and used the "no switch 3 provision" command and it removed it.

Hello,
This switch was used in other time? Maybe it is configured to use a stack and sets this devices as 3 devices in the stack

Try run this command: switch 3 renumber 1

By the way: you can change in your configuration file port identification from g1/0/1-48 to g3/0/1-48

Hello

Just like to add - Be careful when you renumber any switch , make sure you are aware of what this entails, doing this on a live production device especially in a stack could cause you issues

I see where you guys are coming from. It has a label of 3 in the stack and I do not use the stack configuration so I will re-number it. Will I lose my configuration if I re-number it and the configuration is on GigabitEthernet1 already? Thank you.

So I did the renumber from 3 to 1 and it all came up on stack as number 1 but the configuration for GigabitInterface 3/0/1 is still there. I had to renumber back to Stack 3 to get it to work again. How do I remove that part of the config as my secondary switch went down? I am using just a fiber uplink cable.between the switches. Does anyone know? Thank you.
