Configuring the Access Point for Secure Shell

This section describes how to configure the Secure Shell (SSH) feature.
For complete syntax and usage information for the commands used in this section, see the "Secure Shell
Note
Commands" section in Cisco IOS Security Command Reference for Release 12.4.

Understanding SSH

SSH is a protocol that provides a secure, remote connection to a Layer 2 or 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 the following user authentication methods:
