1.2 Configuring Port Security
Alternatively, you can enable port security on port 3 in slot 7 and specify the number
of MAC addresses allowed to access through the port at the same time. In this
example, we will only allow one user to access at a time. That means when the user is
logged in for Internet access on port 3, any user will be blocked.
Note that you cannot activate MAC filtering and port security at the same time.
CI command:
TGE1> lcman port maccount enable 7-3
TGE1> lcman port maccount set 7-3 1
TGE1> config save

function. The following figure shows a network example.
