5 Configuration D-Link Web Smart Switch User Manual
Security > Port Security
Port Security is a security feature that prevents unauthorized computers (with source MAC addresses)
unknown to the Switch prior to stopping auto-learning processing from gaining access to the network.
A given ports’ (or a range of ports') dynamic MAC address learning can be stopped such that the current
source MAC addresses entered into the MAC address forwarding table can not be changed once the port
lock is enabled. Using the drop-down menu, change Admin State to Enabled, input Max Learning Address,
and then click Apply.

Security > Traffic Segmentation
This feature provides administrators to limit traffic flow from a single port to a group of ports on a single
Switch. This method of segmenting the flow of traffic is similar to using VLANs to limit traffic, but is more
restrictive.

Click Apply to enable or disable this feature.
To configure traffic segmentation specify a port or All ports from the switch, using the From Port pull-down
menu and select To Port then click Apply to enter the settings into the Switch’s Traffic Segmentation table.
Click Select All button to check all ports or click Clear button to uncheck all ports.
Security > Safeguard Engine
D-Link’s Safeguard Engine is a robust and innovative technology that automatically throttles the impact of
packet flooding into the switch's CPU. This function helps protect the Web-Smart Switch from being
interrupted by malicious viruses or worm attacks. This option is enabled by default.
