Description
Use the ip portsafe enable command to enable the protocol port security
function to check all IP packets on the interface module. If the destination IP is the
virtual interface IP of the switch, and the corresponding destination protocol port
is not open, the packet will be dropped.
Use the undo ip portsafe enable command to disable the protocol port security
function. Then all packets on the interface module are not checked.
By default, the fabric enables the protocol port security function. So do the
standby module and the interface module.
