4.10.2.3 Port Security 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 chooses to block it, it
will be blocked until that user module decides otherwise.

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 will not be allowed to transmit or
receive traffic.
State Indicates whether the corresponding MAC address is blocked or
forwarding. In the blocked state, it will not be allowed to 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 will
stay 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 (-) will be shown.
