4.5.4.3 Port Security Detail
This page shows the MAC addresses secured by the Port Security module. 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 Port
