Unit power must be cycled whenever Learning mode is enabled or disabled.
IMPORTANT
Learning is an Ethernet switch function that allows the LAN (user) side of the Gigabit Ethernet
port to learn the MAC addresses of the equipment connected to the Gigabit port.
Learning applies only to the LAN (user) side of the port. There is no learning on the WAN
(modem) side of the Gigabit Ethernet port.
If enabled, the interface is in LAN-to-WAN learning mode, and the Gigabit Ethernet Interface
(GBEI) learns connections based on source MAC addresses and ingress ports. The hub thinks the
remote site network nodes are local to the hub site network and does not send the traffic over the
outbound carrier to the remote site.
If disabled, the GBEI passes all packets from the LAN to the WAN.
