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 A

DD 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 D

elete IP button to

delete the IP Address that appears in the IP Address window.
