INFORMATION ABOUT
SWITCH SETTINGS FOR
PORT SECURITY
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.
