Configuring 10/100/1000 switch w/ TFTP

Morning everyone,

Doing a major switch upgrade from 10/100 to all gig switches in the near future.

Here is the question, can I just copy the running out of all of the 10/100s and upload them into the gig switches? I know there will be some tweaks that have to be made but it would save me from doing all of my interface connections and re-configuring my L3 switches.

Thoughts?

You don't really say what model/brand your switches are so it's tough to provide guidance.

Consider that on a Cisco switch, 10/100 ports are referred to in configuration as FastEthernet and gigabit ports are GigabitEthernet. As such, their configs are not going to be directly compatible.

Lots of copy and paste could be used, though.
 
Yeah, using mostly 2960 PoE, the L3s are 3750s.

Wasn't really concerned with the port config since I can just do a range. But we have a ton of QoS setup and VLANs.
 
Well, QoS and VLANs are easy to copy and paste between switches, and the configs between 2960 to 2960S and 3750 to 3750X are pretty much identical when it comes to QoS.

Depending on how detailed your QoS is, the only concern would be whether or not there are different numbers and configurations of buffers. But, since both switches are non-blocking, there isn't really a heavy need for that except on uplink ports...so the config should be quite simple.

Out of curiousity, are you stacking the 3750s? If not, the 3650s are cheaper and have an identical featureset (with the exception of stacking.)

Yeah I have a 4 stack of 3750s as our core. So, if I read you correctly, you suggest the ole copy paste route vs. copy tftp run?
 
Well, remember that copying from TFTP into the running config is a merge, not an overwrite. So it can have some weird side-effects.

I do tend to prefer to copy configs manually.

The other option would be to load the configs into the switch via tftp on boot up.
