MAC Count
(Current, Violating, Limit) : The three columns indicate the number of currently learned MAC
addresses (forwarding as well as blocked), the number of violating MAC address (only counting in Restrict mode)
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 Port Security is not administratively enabled
on the port, the Violating and Limit columns will show a dash (

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 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.
