Disables the SSH server and closes the connection to the SSH server port.
Syntax

Command Default

By default, SSH is enabled, and an SSH connection is established over port 22.

What should this say?

Modes

global configuration mode

Usage Guidelines

The ip ssh disable command is available in the FastIron 08.0.95h release only.

If SSH has been configured on a port other than default port 22, using the no ip ssh disable command re-enables SSH on port 22, disregarding the previous configuration.

The following example disables the SSH server and closes the SSH connection on the default port or on the port where it is configured.
