Port Security Port Status
This page 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.
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.
