Ongoing TFTP requests from several Cat 3500XL switches

I'm experiencing repeated tftp requests for config files from several of the Cat 3500XL switches on the network. These are clustered with standby cluster

commanders activated.

All switches are running IOS (tm) C3500XL Software (C3500XL-C3H2S-M), Version 12.0(5)WC3b.

The following is the the output from the TFTP server that is running on my laptop:

Connection recieved from ***.**.121.251 on port 1765

Read request for file <network-confg>. Mode octet

Error : EACCESS. CreateFile returns 2: <The system cannot find the file specified.>

That is repeated for a couple of times and then the following:

Connection recieved from ***.**.121.251 on port 3179

Read request for file <cisconet.cfg>. Mode octet

Error : EACCESS. CreateFile returns 2: <The system cannot find the file specified.>

And finally changes to this:

Connection recieved from ***.**.121.251 on port 4430

Read request for file <group48-d1-confg>. Mode octet

Error : EACCESS. CreateFile returns 2: <The system cannot find the file specified.>

Non of the switches have anything in their start configs that tell them to look to a tftp server for any of their configs. Any ideas

Regards

Mel

Re: Ongoing TFTP requests from several Cat 3500XL switches

Try doing:

conf t

no service config

end

I sounds like you have service config on (it is the default in some versions) and the switches are trying to TFTP their configs....
