xStack® DES-3528/DES-3552 Series Layer 2 Stackable Fast Ethernet Managed Switch Web UI Reference Guide

To download SSL certificates, configure the parameters in the SSL Certificate Download section described below.

Parameter

Description

Server IP Address

Enter the IPv4 address of the TFTP server where the certificate files are located.

Certificate File Name

Enter the path and the filename of the certificate file to download. This file must have

a .der extension. (Ex. c:/cert.der)

Key File Name

Enter the path and the filename of the key file to download. This file must have a .der

extension (Ex. c:/pkey.der)

Click the

Download

button to download the SSL certificate based on the information entered.

NOTE:

Certain implementations concerning the function and configuration of SSL are not available on the

web-based management of this Switch and need to be configured using the command line

interface.

NOTE:

Enabling the SSL command will disable the web-based switch management. To log on to the

Switch again, the header of the URL must begin with https://. Entering anything else into the

address field of the web browser will result in an error and no authentication will be granted.

SSH

SSH is an abbreviation of Secure Shell, which is a program allowing secure remote login and secure network services

over an insecure network. It allows a secure login to remote host computers, a safe method of executing commands on

a remote end node, and will provide secure encrypted and authenticated communication between two non-trusted

hosts. SSH, with its array of unmatched security features is an essential tool in today’s networking environment. It is a

powerful guardian against numerous existing security hazards that now threaten network communications.

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:

1

Create a user account with admin-level access using the

User Accounts

window. This is identical to creating

any other admin-level User Account on the Switch, including specifying a password. This password is used to

logon to the Switch, once a secure communication path has been established using the SSH protocol.

2

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

SSH User Authentication Mode

window. There are

three choices as to the method SSH will use to authorize the user, which are Host Based, Password, and

Public Key.

3

Configure the encryption algorithm that SSH will use to encrypt and decrypt messages sent between the SSH

client and the SSH server, using the

SSH Authentication Method and Algorithm Setting

s window.

4

Finally, enable SSH on the Switch using the

SSH Configuration

window.

After completing the preceding steps, a SSH Client on a remote PC can be configured to manage the Switch using a

secure, in band connection.

SSH Settings

Users can configure and view settings for the SSH server.
