CISCO ASA 5540 - Telnet Access

Unanswered Question
May 26th, 2007

Hi All,

I have a very basic Telnet access issue after enabling the Telnet Access under device administraion and have added the source ip subnets. But still when I get to do Telnet I get a blank screen with no errors. Some one can help me on this.

Note : I have also added the AAA server settings as local.

Any help greatly appreciated

Thanks in Advance,


I have this problem too.

Please check you config via CLI, and ensure following,

"The security appliance allows Telnet connections to the security appliance for management purposes. You cannot use Telnet to the lowest security interface unless you use Telnet inside an IPSec tunnel.

The security appliance allows a maximum of 5 concurrent Telnet connections per context, if available, with a maximum of 100 connections divided between all contexts. "

Try to add ssh access, and see if you are able to ssh, when you get blank screen via telnet.
