I wonder if i may run a few questions past you guys. We have a Cisco 1700 at one of our sites which is supposed to be managed but due to problems with the third party company i had to go there to perform some work.
I wanted to add in a dns server ip. Because i don't have the enable secret (Third PTY won't tell us) i used the break command normally used for password recovery. then once in used "copy start run".
Q. can i make config changes this way, save the changes then switch the config-register back and reload?
I managed to make the changes - Dhcp pool - dns-server ip's, right? changed the config-reg back and reloaded. No connectivity. anyway i messed around with different ip's eventually put it back to to original powered of for 5 mins and on again and it was ok.
Q: have i missed something out?
Q: could reloading or powering off and on to quickly affect thigs?
Q: Could the router be downloading it's config or something additional from a TFTP server? Is there anything i can check to confirm this on the config?
This is the dns part of the config all i want to do is change 184.108.40.206 for 84.33, should be simple?
Am i right in thinking i would see a boot command/s inside the markers and as i don't and "boot" is not mentioned anywhere else in the config that this router is using it's stored config and not getting one tftp'd.
