Parameter Description
MAC Address & VLAN ID:
The MAC address and VLAN ID for 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 forwarded. 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 detected 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 detected, 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.
Auto-refresh: Check the box next to “Auto-refresh” to refresh the information automatically.
Upper right icon (Refresh): Click on the “Refresh” button to refresh the Port Security Port Status information manually.
