Cisco 1841 interfaces down
Hi
I connected to the console port of an operational Cisco Router 1841 in order to reset the admin password
I followed the first section of this step by step guide
All went well until after the final reboot - as you can see below the FastEthernet0/0.1 and FastEthernet0/0.2 vlans are both down :
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned YES NVRAM administratively down down
FastEthernet0/0.1 XXX.XXX.XXX.XXX YES NVRAM administratively down down
FastEthernet0/0.2 XXX.XXX.XXX.XXX YES NVRAM administratively down down
FastEthernet0/1 unassigned YES NVRAM administratively down down
ATM0/0/0 unassigned YES NVRAM administratively down down
ATM0/0/0.1 unassigned YES unset administratively down down
ATM0/1/0 unassigned YES NVRAM administratively down down
ATM0/1/0.1 unassigned YES unset administratively down down
Virtual-Access1 unassigned YES unset up up
Dialer1 unassigned YES NVRAM up up
Dialer2 unassigned YES NVRAM up up
Even though the FastEthernet0/0 was previously down (as required by the running config) the FastEthernet0/0.1 and FastEthernet0/0.2 vlan interfaces were previously both up
I tried a 'no shut' on both of them but to no avail :
I then tried to enable FastEthernet0/0 which then brought both 0/0.1 and 0/0.2 interfaces up
but the Internet access isn't up so that doesn't seem to be the solution
There is a Catalyst 2960 connected to F0/0
As you can tell I'm no Cisco expert
Any ideas ?
Thanks

Istvan,
Unfortunately there is no improvement
I forgot to mention that all was working fine before my attempt to reset the admin password
Why would I now need to modify the configuration ?

Could the fact that I changed admin password on the 1800 block the Catalyst 2960 from reconnecting to the router ?

Thanks Craig
I forgot that when I executed the "sh ip int brief" I was in the config mode required to reset the password
I upped ATM0/0/0 and ATM0/1/0 so now I have the following status :
but still no Internet access
Should I write to memory and then reboot ?

No probs.
Also, the NAT statements need to go on your subinterfaces, not the physical interface.
Check your default route too. You should use...
ip route 0.0.0.0 0.0.0.0 dhcp
...as you're using DHCP on the dialers.

When I followed the password reset guide it did in fact mention the need to "no shut" the required interfaces, but I wasn't sure which ones
I'm a little confused concerning the NAT statements and the default route
Like I mentioned this router was in operation before I began my password reset quest
If the config was right to begin with, how is it that it was working fine (as was) ?
On which sub-interfaces should I enable the NAT : FE, ATM or Dialer ?
Incidently the the link between the Catalyst and F0/0 on the 1800 still isn't active, any ideas ?

Bingo, thanks Istvan
So basically my issue was simply no having upped the required interfaces following the password reset procedure
Gosh, I feel really silly
Thanks Istvan and Craig for your precious help
