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 Port Security Detail screen in
Figure 4-12-7
appears.

The page includes the following fields:
Object
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 will not be allowed to transmit
or receive traffic.
•
Time of Adding
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.
