MAC authentication
IP Source Guard
QoS
Smart Link
When an up OLT port goes down (because the shutdown is executed on it or the fiber is
unplugged), wait at least five seconds before bringing up the port again (by using the undo
shutdown command or plugging in the fiber). This will prevent the anomalies caused by frequent
ONU registrations and deregistrations.
Currently, the qinq enable downlink and qinq enable uplink commands are not supported on an
OLT port.
