Port Security Switch Status
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 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.
User Module Legend
The legend shows all user modules that may request Port Security services.
User Module Name
The full name of a module that may request Port Security services.
Abbr
A one-letter abbreviation of the user module. This is used in the Users column in the
port status table.
