Configuring Device Security Defining Traffic Control 5 • Port - Indicates the port from which storm control is enabled. • Enable Broadcast Control - Indicates if Broadcast packet types are forwarded on the specific interface. The possible field values are: - Checked - Enables Broadcast packet types to be forwarded. - Unchecked - Disables Broadcast packet types to be forwarded. • Broadcast Mode - Specifies the Broadcast mode currently enabled on the interface. The possible field values are: - Multicast & Broadcast - Counts Broadcast and Multicast traffic together. - Broadcast Only - Counts only Broadcast traffic. - Unknown Unicast, Multicast & Broadcast - Counts Unknown Unicast, Broadcast and Multicast traffic together. This option is available on GE ports only. On FE devices, this option can only be set globally for the device from the Storm Control Page. Relevant on ESW-540, ESW-520, and ESW-520-8p devices. • Broadcast Rate Threshold - Displays the maximum rate (packets per second) at which unknown packets are forwarded. - For FE ports, the rate is 70 - 100,000 Kbps. - For GE ports, the rate is 3,500 - 100,000 Kbps. STEP 3 Modify the relevant fields. STEP 4 Click Apply. Storm control is modified, and the device is updated. Defining Port Security Network security can be increased by limiting access on a specific port only to users with specific MAC addresses. The MAC addresses can be dynamically learned or statically configured. Locked port security monitors both received and learned packets that are received on specific ports. Access to the locked port is limited to users with specific MAC addresses. These addresses are either manually defined on the port, or learned on that port up to the point when it is ESW 500 Series Switches Administration Guide 130
