!- The aaa new-model command causes the local username and password on the router to be used in the absence of other AAA statements. !- Step 1: Configure the hostname if you have not previously done so. The Cisco IOS SSH client configuration on Reed is the same as required for the SSH server configuration on Carter. This puts these devices in a client-server arrangement, where Carter acts as the server, and Reed acts as the client. If you want to have one device act as an SSH client to the other, you can add SSH to a second device called 'Reed'. Enable SSH transport support for the vty. There are four steps required to enable SSH support on a Cisco IOS router:Ĥ. Set Up an IOS Router or Switch as SSH Client Test to ensure that non-SSH users cannot Telnet to the router 'Carter'. If you want to prevent non-SSH connections, add the transport input ssh command under the lines to limit the router to SSH connections only. Optional Configuration Sets Prevent Non-SSH Connections After you add the SSH configuration, test your ability to access the router from the PC and UNIX station. !- Generate an SSH key to be used with SSH.Īt this point, the show crypto key mypubkey rsa command must show the generated key. In order to test authentication with SSH, you have to add to the previous statements in order to enable SSH on Carter and test SSH from the PC and UNIX stations. !- Instead of aaa new-model, you can use the login local command.

Note: Throughout this document vty is used to indicate 'Virtual Terminal Type'. (Authentication through the line password is not possible with SSH.) This example shows local authentication, which lets you Telnet into the router with username 'cisco' and password 'cisco.' Authentication can be with a local username and password or with an authentication, authorization, and accounting (AAA) server that runs TACACS+ or RADIUS. Test Authentication Authentication Test without SSHįirst test the authentication without SSH to make sure that authentication works with the router Carter before you add SSH.

SSH Version 2.0 (SSH v2) support was introduced in Cisco IOS platforms and images start in Cisco IOS Software Release 12.1(19)E. SSH terminal-line access (also known as reverse-Telnet) was introduced in Cisco IOS platforms and images start in Cisco IOS Software Release 12.2.2.T.SSH was introduced into these Cisco IOS platforms and images: The information in this document is based on Cisco IOS 3600 Software (C3640-IK9S-M), Release 12.2(2)T1. If your network is live, ensure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. The Cisco IOS image used must be a k9(crypto) image in order to support SSH.

This document describes how to configure and debug Secure Shell (SSH) on Cisco routers or switches that run Cisco IOS ® Software.
