DES-3550 Layer 2 Fast Ethernet Switch  

31 

 SSH 

C

OMMANDS

 

The steps required to use the Secure Shell (SSH) protocol for secure communication between a remote PC (the SSH Client) 
and the Switch (the SSH Server), are as follows: 

• 

• 

• 

• 

Finally, enable SSH on the Switch using the 

enable ssh

 command. 

• 

Command Parameters 

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 algrothim that SSH will use to encrypt and decrypt messages sent between the SSH Client 
and the SSH Server.  

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. 

enable ssh 

 

 

[password | publickey | hostbased] [enable | disable] 

 

config ssh server 

{maxsession <int 1-8> | contimeout <sec 120-600> | 
authfail <int 2-20> | rekey [10min | 30min | 60min | never]  

show ssh server 

 

config ssh user 
 

 

<username> authmode [hostbased [hostname <domain_name> | 
hostname_IP <domain_name> <ipaddr>] | password | publickey] 

show ssh user 

 

config ssh algorithm 

[3DES | AES128 | AES192 | AES256 | arcfour | blowfish | cast128 
| twofish128 | twofish192 | twofish256 | MD5 | SHA1 | RSA | DSA] 
[enable | disable] 

show ssh algorithm 

 

disable ssh 

config ssh authmode 

show ssh authmode 

Each command is listed, in detail, in the following sections.
