Function name:
Port Security – Port Status
Function description:
The function 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.
Parameters description:
MAC Address & VLAN The MAC address and VLAN ID that is seen on this port. If
