i have got myself locked out of my router. All devices on the network have to access the TACACS server for authentication and authorisation. However i think i misconfigured the router and now i cant login... as i get the login prompt but the athentication failed. Is there any way i can be able to login again ? I have tried using the console but still the same problem.
I have tried what you advised. i logged on to the directly connected router, created an Access list blocking UDP port 49 through from source 10.151.0.46.. which is the router i have problems logging in.
access-list 100 permit ip any any
access-list 100 deny udp host 10.151.0.46 eq tacacs any
i then applied that filter to the interface the 10.151.0.46 is connected to,
ip address 10.151.0.45 255.255.255.252
ip access-group 100 in
ip access-group 100 out
no ip directed-broadcast
tried to telnet (from 10.151.0.45 to 10.151.0.46 ) but still get the error message below...
Trying 10.151.0.46 ... Open
% Authentication failed.
[Connection to 10.151.0.46 closed by foreign host]
Maybe i am missing something out that you can highlight on..
