Command Reference Guide

Line (Telnet) Interface Config Command Set

access-class <listname> in

Use the access-class in command to restrict Telnet access using a configured access list. Received packets

passed by the access list will be allowed. Use the access list configuration to deny hosts or entire networks

or to permit specified IP addresses.

Syntax Description

<listname> Alphanumeric descriptor for identifying the configured access list (all access list

descriptors are case-sensitive).

Default Values

By default, there are no configured access lists associated with Telnet sessions.

Command Modes

(config-telnet X)# Line Configuration Mode required.

Functional Notes

When using the access-class in command to associate an access list with a Telnet session, remember to

duplicate the access-class in command for all configured Telnet sessions 0 through 4. Telnet access to

the unit using a particular Telnet session is not possible. Users will be assigned the first available Telnet

session.

Usage Examples

The following example associates the access list Trusted (to allow Telnet sessions from the

192.22.56.0/24 network) with all Telnet sessions (0 through 4):

Create the access list:

(config)#ip access-list standard Trusted

(config)#permit 192.22.56.0 0.0.0.255

Enter the line (telnet) :

(config)#line telnet 0 4

Associate the access list with the Telnet session:

(config-telnet0-4)#access-class Trusted in
