If the periodical broadcastfunction is not desired, you can enable triggered update on the VLAN interfaces of theswitch. This allows the switch to broadcast update packets only when route or serviceinformation changes, thus avoiding broadcast flooding.In some cases, split-horizon must be disabled to ensure correct transmission of routinginformation. Split horizon eliminates routing loops by forbidding the switch to send therouting information out of the interface where it is received. Disable split horizon onlywhen necessary and with cautions, because it can result in routing loops.Novell NetWare defines the IPX broadcast packet of Type 20 for the network basicinput/output system (NetBIOS). You can enable/disable the forwarding of Type 20broadcast packets to other segments as required.Follow these steps to configure IPX forwarding:To do… Use the command… RemarksEnter system view system-view —Enable IPX ipx enable RequiredDisabled by default.Enter VLAN interface view interface Vlan-interfacevlan-id —
