Priority IP Queuing
The Priority IP Queuing window ( Figure 28 , below), displays after clicking on the Priority
Queuing button in the General Configuration window. Priority IP Queuing lets you prioritize
packets generated from selected devices (specified by source IP Address), to ensure their delivery
under peak WAN traffic loads.
The IP packets will not take precedence over other packets already queued on the WAN, but,
reserved, internal queue space will be made available to these packets to avoid discarding them
during oversubscribed peak loads. This feature is ideal for use with Inverse Multiplexing, to ensure
that attached routers, running the IP RIP (Routing Information Protocol), do not time out, and to
ensure that management packets get through.
To configure this feature, click the ADD IP button, and the Add Priority IP Address window,
shown in
Figure 29 , appears. Enter the IP Address(es) that are to receive priority treatment in the
IP Address window. You can use the IP Address window scroll bar and the Delete IP button to
delete the IP Address that appears in the IP Address window.
