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.

Displaying Information About Learned Mac Addresses

Use the Port Security Port Status page to show the entries authorized by port security services, including MAC
address, VLAN ID, time added to table, age, and hold state.

The full name of a module that may request Port Security services.
A one-letter abbreviation of the user module. This is used in the Users column in
the port status table.
The port number for which the status applies. Click the port number to see the sta-
tus for this particular port.
Each of the user modules has a column that shows whether that module has
enabled Port Security or not. A '-' means that the corresponding user module is
not enabled, whereas a letter indicates that the user module abbreviated by that
letter has enabled port security.
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 Webpage.
The two columns indicate the number of currently learned MAC addresses (for-
warding as well as blocked) and the maximum number of MAC addresses that
can be learned on the port, respectively.
If no user modules are enabled on the port, the Current column will show a dash (-
). If the Limit Control user module is not enabled on the port, the Limit column will
show a dash (-).
The MAC address seen on this port. If no MAC addresses are learned, a single
row stating No MAC addresses attached is displayed.
The VLAN ID seen on this port.
Indicates whether the corresponding MAC address is blocked or forwarding. In
the blocked state, it will not be allowed to transmit or receive traffic.
