TL-SG2008 switch integrates multiple functions with excellent performance, and is friendly to manage, which can fully meet the need of the users demanding higher networking performance.

2.2 Main Features

•Resiliency and Availability

+IEEE 802.1s Multiple Spanning Tree provides high link availability in multiple VLAN environments.

+Multicast snooping automatically prevents flooding of IP multicast traffic.

+Root Guard protects root bridge from malicious attack or configuration mistakes

•Layer 2 Switching

+Supports up to 512 VLANs simultaneously (out of 4K VLAN IDs).

•Quality of Service

+Supports L2/L3 granular CoS with 4 priority queues per port.

+Rate limiting confines the traffic flow accurately according to the preset value.

•Manageability

+Supports Telnet, SNMP v1/v2c/v3, RMON and web access.

zBOOTP: When this option is selected, the switch will obtain network parameters from the BOOTP Server.

Management VLAN: Enter the ID of management VLAN, the only VLAN through which you can get access to the switch. By default VLAN1 owning all the ports is the Management VLAN and you can access the switch via any port on the switch. However, if another VLAN is created and set to be the Management VLAN, you may have to reconnect the management station to a port that is a member of the Management VLAN.

IP Address: Enter the system IP of the switch. The default system IP is 192.168.0.1 and you can change it appropriate to your needs.

Subnet Mask: Enter the subnet mask of the switch.

Default Gateway: Enter the default gateway of the switch.

Note:

1.Changing the IP address to a different IP segment will interrupt the network communication, so please keep the new IP address in the same IP segment with the local network.

2.The switch only possesses an IP address. The IP address configured will replace the original IP address.

3.If the switch gets the IP address from DHCP server, you can see the configuration of the switch in the DHCP server; if DHCP option is selected but no DHCP server exists in the network, the switch will keep obtaining IP address from DHCP server until success.

4.If DHCP or BOOTP option is selected, the switch will get network parameters dynamically from the Internet, which means that IP address, subnet mask and default gateway can not be configured.

5.By default, the IP address is 192.168.0.1.

4.2 User Management

User Management functions to configure the user name and password for users to log on to the Web management page with a certain access level so as to protect the settings of the switch from being randomly changed.

4.4.2 SSL Config

SSL (Secure Sockets Layer), a security protocol, is to provide a secure connection for the application layer protocol (e.g. HTTP) communication based on TCP. SSL is widely used to secure the data transmission between the Web browser and servers. It is mainly applied through ecommerce and online banking.

SSL mainly provides the following services:

1.Authenticate the users and the servers based on the certificates to ensure the data are transmitted to the correct users and servers;

2.Encrypt the data transmission to prevent the data being intercepted;

3.Maintain the integrality of the data to prevent the data being altered in the transmission.

Adopting asymmetrical encryption technology, SSL uses key pair to encrypt/decrypt information. A key pair refers to a public key (contained in the certificate) and its corresponding private key. By

20

default the switch has a certificate (self-signed certificate) and a corresponding private key. The Certificate/Key Download function enables the user to replace the default key pair.

After SSL is effective, you can log on to the Web management page via https://192.168.0.1. For the first time you use HTTPS connection to log into the switch with the default certificate, you will be prompted that “The security certificate presented by this website was not issued by a trusted certificate authority” or “Certificate Errors”. Please add this certificate to trusted certificates or continue to this website.

On this page you can configure the SSL function.

Choose the menu System→Access Security→SSL Config to load the following page.

Figure 4-16 SSL Config

The following entries are displayed on this screen:

¾Global Config

SSL:	Select Enable/Disable the SSL function on the switch.

¾Certificate Download

Certificate File: Select the desired certificate to download to the switch. The

certificate must be BASE64 encoded.

¾Key Download

Key File:	Select the desired SSL key to download to the switch. The key
	must be BASE64 encoded.

Note:

1.The SSL certificate and key downloaded must match each other; otherwise the HTTPS connection will not work.

2.The SSL certificate and key downloaded will not take effect until the switch is rebooted.

3.To establish a secured connection using https, please enter https:// into the URL field of the browser.

21

4.It may take more time for https connection than that for http connection, because https connection involves authentication, encryption and decryption etc.

4.4.3 SSH Config

As stipulated by IFTF (Internet Engineering Task Force), SSH (Secure Shell) is a security protocol established on application and transport layers. SSH-encrypted-connection is similar to a telnet connection, but essentially the old telnet remote management method is not safe, because the password and data transmitted with plain-text can be easily intercepted. SSH can provide information security and powerful authentication when you log on to the switch remotely through an insecure network environment. It can encrypt all the transmission data and prevent the information in a remote management being leaked.

Comprising server and client, SSH has two versions, V1 and V2 which are not compatible with each other. In the communication, SSH server and client can auto-negotiate the SSH version and the encryption algorithm. After getting a successful negotiation, the client sends authentication request to the server for login, and then the two can communicate with each other after successful authentication. This switch supports SSH server and you can log on to the switch via SSH connection using SSH client software.

SSH key can be downloaded into the switch. If the key is successfully downloaded, the certificate authentication will be preferred for SSH access to the switch.

Choose the menu System→Access Security→SSH Config to load the following page.

Figure 4-17 SSH Config

The following entries are displayed on this screen:

¾Global Config

SSH:	Select Enable/Disable SSH function.

Protocol V1: Select Enable/Disable SSH V1 to be the supported protocol.

Protocol V2: Select Enable/Disable SSH V2 to be the supported protocol.

22

Idle Timeout: Specify the idle timeout time. The system will automatically release the connection when the time is up. The default time is 120 seconds.

Max Connect: Specify the maximum number of the connections to the SSH server. No new connection will be established when the number of the connections reaches the maximum number you set. The default value is 5.

¾Key Download

Key Type: Select the type of SSH key to download. The switch supports

three types: SSH-1 RSA, SSH-2 RSA and SSH-2 DSA.

Key File: Select the desired key file to download.

Download: Click the Download button to down the desired key file to the switch.

Note:

1.Please ensure the key length of the downloaded file is in the range of 256 to 3072 bits.

2.After the key file is downloaded, the user’s original key of the same type will be replaced. The wrong uploaded file will result in the SSH access to the switch via Password authentication.

Application Example 1 for SSH:

¾	Network Requirements
1.	Log on to the switch via password authentication using SSH and the SSH function is enabled
	on the switch.
2.	PuTTY client software is recommended.
¾	Configuration Procedure

1.Open the software to log on to the interface of PuTTY. Enter the IP address of the switch into Host Name field; keep the default value 22 in the Port field; select SSH as the Connection type.
