New router

[todd1019]

We just installed a new 3745 router with IOS Version 12.2(8)T10.

Apparently this router out of the box or through an inadvertant programming change is trying to TFTP download configs every ten minutes. The configs arent there so I am continually seeing alerts on my SNMP server.

Does anyone know how to turn this auto-TFTP update off. I have never run across this before.

Thanks in advance.

Do a show version. Config register value (displayed at the bottom) should be 0x2102. To change it use:

router(config)# config-register 0x2102

this will make router boot from flash and turns off searching on TFTP.

You can also use

router(config)# no service config

and save this command to nvram, so in case your router reloads, it will not try to search TFTP.

Hope this helps

The config register is (Configuration register is 0x2102)
That was the first thing I looked at.

Every ten minutes like clock work it is trying to download the config file.

The command no service config, did it help? I tried a search via

http://www.cisco.com/univercd

and found another command which may help:

no boot config

Other option is maybe to upgrade IOS, because this oone is faulty... or block the tftp by access-list

Do you have a link to the faults for this version of IOS?

I did use the no service command I will need to check in ten minutes and see if it worked.

no boot config is not a valid command in this router.

Only options for no boot are:
bootstrap Bootstrap image file
host Router-specific config file
network Network-wide config file
system System image file

you can try boot flash: within the config mode. This may help in the problem.

I think the no service config command might have done it.

Thanks.
