Port
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.
