Configuration Using the Web-based Utility

Broadcast Control  Select the checkbox to apply Broadcast control on the selected interface. Broadcast control limits the amount of Broadcast packet types to be forwarded. The default is not selected (disabled).

Mode  Specifies the Broadcast mode currently enabled on the device. The possible values are:

Multicast & Broadcast  Counts Broadcast and Multicast traffic together.

Broadcast Only  Counts only Broadcast traffic.

Rate Threshold  The maximum rate (packets per second) at which unknown packets are forwarded. The ranges are 70 kbps to 100 Mbps for FE ports, and 3.5 to 100 Mbps for GE ports. The default value is 3500 kbps.

The Update button adds the Storm Control settings to the Storm Control table at the bottom of the screen.

Security > RADIUS

The RADIUS screen is used to configure a Remote Authorization Dial-In User Service (RADIUS) server for user authentication.

Security > RADIUS

RADIUS servers provide additional security for networks by providing a centralized authentication method for web access. Up to eight RADIUS servers can be configured. The Switch attempts authentication using the listed sequence of servers. The process ends when a server either approves or denies access to a user.

IP Address  Enter the IP address of the authentication server.

Priority  The server priority. The possible values are 0 to 65535, where 0 is the highest priority. This priority determines the order in which RADIUS servers are queried when more than one RADIUS server is configured. The default priority is 0.

Authentication Port  Enter the authentication port. The authentication port is used to verify the RADIUS server authentication. The default value is 1812.

Number of Retries  Defines the number of transmitted requests sent to RADIUS server before a failure occurs. The possible values are 1 to 10. The default is 3.

Timeout for Reply  Defines the amount of the time in seconds the device waits for an answer from the RADIUS server before retrying the query, or switching to the next server. The possible values are 1 to 30. The default is 3.

Dead Time  Defines the amount of time (minutes) that a RADIUS server is bypassed for service requests. The range is 0 to 2000. The default is 0 minutes.

Key String  Defines the default key string used to authenticate and encrypt all RADIUS communications between the device and the RADIUS server. This key must match the RADIUS encryption.

Source IP Address  Defines the source IP address that is used for communication with RADIUS servers.

Usage Type  This is the RADIUS server authentication type. The possible values are:

Login  (Default value) Indicates that the RADIUS server is used for authenticating user name and passwords.

802.1X  Indicates that the RADIUS server is used for 802.1X authentication.

All  Indicates that the RADIUS server is used for authenticating user name and passwords, and 802.1X port authentication.

Click Add to List to add the RADIUS configuration to the RADIUS table at the bottom of the screen.

Click Save Settings to save the changes, or Cancel Changes to cancel the changes.

QoS

Network traffic is usually unpredictable, and the only basic assurance that can be offered is best effort traffic delivery. To overcome this challenge, Quality of Service (QoS) is applied throughout the network. This ensures that network traffic is prioritized according to specified criteria, and that specific traffic receives preferential treatment. QoS in the network optimizes network performance and entails two basic facilities:

Classifying incoming traffic into handling classes, based on an attribute, including:

The ingress interface

Packet content

A combination of these attributes

Providing various mechanisms for determining the allocation of network resources to different handling classes, including:

24/48-Port 10/100 + 4-Port Gigabit Smart Switch with Resilient Clustering Technology and PoE
