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 , and then click Apply to
confirm the setting.

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.
