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:

For more information about SSH, see Part 5, “Other Security Features” in the Cisco IOS Security Configuration

Guide for Release 12.4 .

The SSH feature in this software release does not support IP Security (IPsec).Note
