Port Status
This section shows the MAC addresses secured by the Port Security module. 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 user module decides to block it, blocking continues
until that user module decides otherwise.
To view the Port Security Port Status in the web interface:
1. Navigate to Security > Port Security > Port Status .
2. Specify the Port to view the status.

Parameter Description
MAC Address & VLAN ID The MAC address and VLAN ID that is seen on this port. If no MAC addresses are
learned, a single row stating "No MAC addresses attached" is displayed.
State Indicates whether the corresponding MAC address is blocked or forwarding. In the
blocked state, it cannot transmit or receive traffic.
Time of Addition Shows the date and time when this MAC address was first seen on the port.
Age/Hold If at least one user module has decided to block this MAC address, it stays in the
blocked state until the hold time (measured in seconds) expires. If all user
modules have decided to allow this MAC address to forward, and aging is
enabled, the Port Security module will periodically check that this MAC address
still forwards traffic. If the age period (measured in seconds) expires and no
frames have been seen, the MAC address will be removed from the MAC table.
Otherwise a new age period will begin.
If aging is disabled or a user module has decided to hold the MAC address
indefinitely, a dash (-) displays.
