Security > IP Access List
Use the IP Access List (also known as Management Access List) screen to specify IP addresses that are to be allowed to manage the device, using an IP address and wildcard mask.
Security > IP Access List
IP Address Enter the IP address to be allowed.
Wildcard Mask Enter the IP address wildcard mask. Wildcard masks specify which bits are used and which bits are ignored. A wild card mask of 255.255.255.255 indicates that no bit is important. A wildcard of 0.0.0.0 indicates that all the bits are important. For example, if the source IP address is 149.36.184.198 and the wildcard mask is 255.36.184.00, the first eight bits of the IP address are ignored, while the last eight bits are used.
Add to List Click this button to save the IP address and Wildcard Mask. The information will appear in the list at the bottom of the screen.
The bottom portion of the IP Access List screen displays the current IP access list, where each entry consists of an IP Address and Wildcard Mask. To delete an entry from the list, select it and click Delete.

Security > Storm Control
The Storm Control screen is used to configure broadcast and multicast storm control.
Security > Storm Control
Storm Control enables limiting the amount of Multicast and Broadcast frames accepted and forwarded by the Switch. A Broadcast Storm results when an excessive amount of broadcast messages is simultaneously transmitted across a network by a single port. Forwarded message responses are heaped onto the network, straining network resources or causing the network to time out.
To enable Storm Control on a port, you specify the packet type (broadcast/multicast) and maximum transmission rate. The system measures the incoming Broadcast and Multicast frame rates separately on each port and discards frames when the rate exceeds the specified maximum.
Interface Indicates the interface from which storm control is enabled.
•Port Select the port from the
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.
