◆ VLAN ID – The VLAN ID seen on this port.
◆ 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 is still forwarding 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.
