Hi Raj,
We need more information regarding the issue. Would you please provide us the configuration of NAS?
To make sure that you've correctly added the NAS on the TACACS server.
To make sure that the key is same on both sides.

Hi
every thing was working fine till yester day for years but from last 1 day we have intermediate disconection to Tacacs in during those disconnection we can log in only by local passwords

Check for someone duplicated ip address of the TACACS server. Disconnect the TACACS from the network and ping for the TACACS ip .If its still pinging ...That will be the issue.
Hope That helps.

hi adhitya,
You mentioned that the router is using a local database to authenticate users. right? So a Local database should be the second option if you can't reach the TACACS server. How to verify that?
- ping the server from NAS.
Is that okay?
- then telnet to the server by using TCP port that you've defined.
Is that okay?
- then check the logging of the server.
Please let us know how things work out.

aside from pings, add traceroute on your diagnostics. this will let you know where you disconnect. troubleshoot from there. can you check on your tacacs-server and AAA config if there were changes.
