13-6.2 Status
This section 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.

Parameter description:

Port :
The port number for which the status applies. Click the port number to see the status for this
particular port.

State :
Shows the current state of the port. It can take one of four values:
Disabled: No user modules are currently using the Port Security service.
Ready: The Port Security service is in use by at least one user module, and is awaiting frames
from unknown MAC addresses to arrive.
Limit Reached: The Port Security service is enabled by at least the Limit Control user module,
and that module has indicated that the limit is reached and no more MAC addresses should
be taken in.
Shutdown: The Port Security service is enabled by at least the Limit Control user module,
and that module has indicated that the limit is exceeded. No MAC addresses can be learned
on the port until it is administratively re-opened on the Limit Control configuration Web-
page.
