Is there any truth to this claim?

Specifically we're talking about a 2501 whose show version output appears below.

The eBay seller claims "I have always used tftp to push from the routers out not in the conf t mode because not all routers support being a tftp-server"

I think that's probably bs; when we're talking about a 2501 running IOS 12.3.

I've read instead that on the 2500 series, IOS is both stored in, and executed from, Flash.

It should read any "modern" router can be a tftpserver . Even low end switches like a 2950 support that function . A 2500 is from the mid 1990's so its way out of date.

Yes, I have used it.

The available parameters are listed as




"flash:" is, I think bizarrely, NOT an option. Whereas I can tftp-server any flash files with any of my _older_ IOS images.
