3-­‐5.2.1.1 Switch
This section shows the Port Security status. Port Security is a module with no direct configuration.
Configuration comes indirectly from other modules— the user modules. When a user module has
enabled port security on a port, the port is set up for software-­‐based learning. In this mode, frames
from unknown MAC addresses are passed on to the port security module, which in turn asks all user
modules whether to allow this new MAC address to forward or block it. For a MAC address to be set
in the forwarding state, all enabled user modules must unanimously agree on allowing the MAC
address to forward. If only one chooses to block it, it will be blocked until that user module decides
otherwise. The status page is divided into two sections—one with a legend of user modules and one
with the actual port status.
