Configuring Telnet Access

To identify the client IP addresses allowed to connect to the ASA using Telnet, perform the following
steps.
Detailed Steps
Command
Step 1
telnet source_IP_address mask
source_interface
Example:
hostname(config)# telnet 192.168.1.2
255.255.255.255 inside
Step 2
telnet timeout minutes
Example:
hostname(config)# telnet timeout 30
Examples
The following example shows how to let a host on the inside interface with an address of 192.168.1.2
access the ASA:
hostname(config)# telnet 192.168.1.2 255.255.255.255 inside
The following example shows how to allow all users on the 192.168.3.0 network to access the ASA on
the inside interface:
hostname(config)# telnet 192.168.3.0 255.255.255.0 inside
Using a Telnet Client
To gain access to the ASA CLI using Telnet, enter the login password set by the password command.
(9.0(2) and later) The default Telnet login password was removed; you must manually set the password
before using Telnet. See the

If you cannot make a Telnet or SSH connection to the ASA interface, make sure that you have
enabled Telnet or SSH to the ASA according to the instructions in the

Purpose
For each address or subnet, identifies the IP addresses from
which the ASA accepts connections.
If there is only one interface, you can configure Telnet to access
that interface as long as the interface has a security level of 100.
Sets the duration for how long a Telnet session can be idle
before the ASA disconnects the session.
Set the timeout from 1 to 1440 minutes. The default is 5
minutes. The default duration is too short in most cases and
should be increased until all pre-production testing and
troubleshooting have been completed.
