7.7.2 Switch Status
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.
