Can I swap this devices?

jacobyoby · ‎09-24-2018

I have a 2911 Router that I'm looking to swap with a 2951 Router.

They have different cards and modules.

Is it possible to switch them and still support the same config? I also attached configs.

If they can be swapped how can I match up the interfaces.

Here is the inventory of both routers.

From what I can see, everything should be compatible.

The only component I didn't see for the 2900 was the VWIC3-4MFT-T1/E1, but then it shouldn't work in the 2901, but that's not the case, and this link says it should:

Hope this helps

Should be fine.
