Copy config to different model switch

[briangreig]

Hi all,

I have some 3560's that are in service that need to be swapped out with 3750's.  Is there a way to copy over the current configs from the 3560's to the 3750's without having to rebuild the config files from scratch?

Thanks

Hi,

You can copy the running config from the 3560s to a tftp server and than load it from tftp server into 3750s, but the problem is that the port numbering for 3560 is different than the 3750 series. For example; port 0/10 from a 3560 is 1/0/10 on a 3750.  I think, you may need to copy the config from each switch to a notepad, make all the changes you need to make and than paste it to the 3750. 

Also, between the 2 platforms most commands are the same but you may see some commands that work on a 3560 but not on a 3750 and vice versa.

HTH,

Thank you for the help.  I ended up redoing it any way.  When I uploaded the newly configured file to another switch however, the switch isnt allowing vlan2 or 3 to come up now.  Not sure what I messed up.  I will post the config in a bit.

Thanks

Quick question,

I rebuilt the config files on my spare 3750 for each different switch and saved each config file.  When I went to upload the new config files to the switches I needed to change, vlan2 and vlan3 stay down.  Is there something I am missing?

Thanks

So, in the old switch vlan 2 and 3 worked fine but not in the switch?

Can you post the new config?

"sh run"

Creating interface vlan X will not create VLAN X.
VLAN on switch in transparent or server VTP (vtp domain and password must match) mode is created by issuing  commands
vlan x

or
interface fa0/0
switchport mode access
swithcport access vlan x

additionally, for SVI to be in up up state VLAN need to have at least one active port (can be vlan assigned to trunk).

Tshoot commands:
show interface status
show interface trunk
show vlan brief
show spanning-tree vlan x
