Using Secure Shell 2

Secure Shell 2 (SSH2) is a feature of the ExtremeXOS software that allows you to encrypt session data between a network administrator using SSH2 client software and the switch or send encrypted data from the switch to an SSH2 client on a remote system. Configuration, image, public key, and policy files can be transferred to the switch using the Secure Copy Protocol 2 (SCP2).

The ExtremeXOS SSH2 switch application works with the following clients: Putty, SSH2 (version 2.x or later) from SSH Communication Security, and OpenSSH (version 2.5 or later).

The switch accepts IPv6 connections.

Up to eight active SSH2 sessions can run on the switch concurrently. If you enable the idle timer using the enable idletimeout command, the SSH2 connection times out after 20 minutes of inactivity by default. If you disable the idle timer using the disable idletimeout command, the SSH2 connection times out after 60 minutes of inactivity, by default. You can modify the timeout value using the command configure ssh2 idletimeout <minutes> where <minutes> can be from 1 to 240 . For more information, refer to the help command for configure ssh2 idletimeout. If a connection to an SSH2 session is lost inadvertently, the switch terminates the session within 60 minutes.
