3-7.3 Port Status
This section 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.
Web Interface
