Displaying Port Security Switch Status
Use the Port Security Switch Status page to show information about MAC address learning
for each port, including the software module requesting port security services, the service
state, the current number of learned addresses, and the maximum number of secure
addresses allowed.
Port Security is a module with no direct configuration. Configuration comes indirectly from
other software 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 be forwarded or blocked. 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 that may
request port security services, and one with the actual port status.
