Configuring the Access Point for Secure Shell
This section describes how to configure the Secure Shell (SSH) feature.
Note For complete syntax and usage information for the commands used in this section, refer to the “Secure
Shell Commands” section in the Cisco IOS Security Command Reference for Release 12.3.

Understanding SSH

SSH is a protocol that provides a secure, remote connection to a Layer 2 or a Layer 3 device. There are
two versions of SSH: SSH Version 1 and SSH Version 2. This software release supports both SSH
versions. If you do not specify the version number, the access point defaults to Version 2.
SSH provides more security for remote connections than Telnet by providing strong encryption when a
device is authenticated. The SSH feature has an SSH server and an SSH integrated client. The client
supports these user authentication methods:
•RADIUS (for more information, see the “Controlling Access Point Access with RADIUS” section
on page 5-11)
•Local authentication and authorization (for more information, see the “Configuring the Access Point
for Local Authentication and Authorization” section on page5-21)
For more information about SSH, refer to Part 5, “Other Security Features” in the Cisco IOS Security
Configuration Guide for Release 12.3.
Note The SSH feature in this software release does not support IP Security (IPsec).

Configuring SSH

Before configuring SSH, download the crypto software image from Cisco.com. For more information,
refer to the release notes for this release.
For information about configuring SSH and displaying SSH settings, refer to Part 5, “Other Security
