If the newly configured length of a service information queue is less than the original
one, the current service entries are not deleted. If the number of the service entries of
the same type reaches the specified value, new service information is not added.

3.2.6 Configuring IPX Forwarding
IPX RIP and SAP periodically broadcast update packets. If the periodical broadcast
function is not desired, you can enable triggered update on the VLAN interfaces of the
switch. This allows the switch to broadcast update packets only when route or service
information changes, thus avoiding broadcast flooding.
In some cases, split-horizon must be disabled to ensure correct transmission of routing
information. Split horizon eliminates routing loops by forbidding the switch to send the
routing information out of the interface where it is received. Disable split horizon only
when necessary and with cautions, because it can result in routing loops.
Novell NetWare defines the IPX broadcast packet of Type 20 for the network basic
input/output system (NetBIOS). You can enable/disable the forwarding of Type 20
broadcast packets to other segments as required.
