4.12.7 Port Security Detail

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. The Port Security Detail screen in
Figure 4-12-7 appears.
The page includes the following fields:
Object
• MAC Address &
VLAN ID
• State
• Time of Addition
