Hi,
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 1.0.84.187 for 84.33, should be simple?
ip dhcp pool 0
network 172.16.0.0 255.255.0.0
default-router 172.16.0.15
dns-server 1.0.84.8 1.0.84.187 158.152.1.43 158.152.1.58
domain-name parkside.net
lease infinite
Q: Is this part saying that 1.0.84.187 and 158.152.1.43 are not being used for dns?
no ip domain lookup
ip name-server 1.0.84.187
ip name-server 158.152.1.43
ip cef
no scripting tcl init
no scripting tcl encdir
Sorry i know thats long winded. Any help on any part of my problem would be much appreciated.
Kind regards

Hello,
check for any lines starting with ´boot´ in the upper part of the configuration, it is very well possible that the router is configured to boot a specific file, or from a TFTP server.
Regarding the change of the DNS server IP address, in DHCP pool configuration mode, first delete the existing line:
no dns-server 1.0.84.8 1.0.84.187 158.152.1.43 158.152.1.58
and reenter it:
dns-server 1.0.84.8 1.0.84.33 158.152.1.43 158.152.1.58
The DNS servers specified with the ´ip name-server´ command are used for non-DHCP clients.

Hi,
there are not any boot commands only the
boot-start-marker
boot-end-marker
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.
Many thanks
