Chapter 22 - SSH Commands
The steps required to use the SSH protocol for secure communication between a remote PC (the SSH Client) and the Switch (the SSH Server), are as follows:
Create a user account with admin-level access using the create account admin <username> <password> command.This is identical to
creating any other admin-lever User account on the Switch, including specifying a password.This password is used to login to the Switch, once secure
communication has been established using the SSH protocol.
Configure the user account to use a specified authorization method to identify users that are allowed to establish SSH connections with the Switch
using the config ssh user authmode command.There are three choices as to the method SSH will use to authorize the user, and they are
password,publickey and hostbased.
Configure the encryption algorithm that SSH will use to encrypt and decrypt messages sent between the SSH Client and the SSH Server.
Finally, enable SSH on the Switch using the enable ssh command.
After following the above steps, you can configure an SSH Client on the remote PC and manage the Switch using secure, in-band communication.
The Secure Shell (SSH) commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.
Command Parameters
enable ssh
disable ssh
config ssh authmode [password | publickey | hostbased] [enable | disable]
show ssh authmode
config ssh server {maxsession <int 1-3> | contimeout <sec 120-600> | authfail <int 2-20> | rekey [10min | 30min | 60min |
never]
show ssh server
config ssh user <username> authmode {hostbased [hostname <string 32> | hostname_IP <string 32> <ipaddr>} | password |
publickey | none]
show ssh user authmode
config ssh algorithm [3DES | AES128 | AES192 | AES256 | arcfour | blowfish | cast128 | twofish128 | twofish192 | twofish256 | MD5 |
SHA1 | DSA | RSA] [enable | disable]
