Jan 03, 2012 · Cisco Catalyst switches include remote configuration options such as connecting through telnet, SSH and web interface. If you are configuring a Cisco Catalyst switch but are uncomfortable with the Cisco command line (CLI), enabling configuration access through a web browser is a logic choice. Jul 08, 2011 · If remote CLI access to the firewalls is needed, SSH is the protocol of choice. It provides the same terminal services that Telnet does but with the significant advantage of encrypting traffic between client and server (the firewall receiving the connection).

Traffic through the remote console session is always encrypted, but if you enable Telnet and connect with a standard non-encrypted client then you are still transmitting unencrypted text.
On the remote ASA that you are trying to telnet to, you would need to add the following command: management-access inside. telnet <255.255.255.255> inside. Also, your local ASA where the core switch is connected needs to allow the telnet connection through to the remote ASA.Allen bradley plc 5 programming software
