This page 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 is
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.

the port status table.

Users
Each of the user modules has a column that shows whether that module has
enabled Port Security or not. A '-' means that the corresponding user module is
not enabled, whereas a letter indicates that the user module abbreviated by that
letter (see Abbr) has enabled port security.
