This screen shows the Port Security status. Port Security is a module with no direct
configuration. Configuration comes indirectly from 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 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.
