Software inventory application

It is extremely unlikely that the WAN aggregator will be serving anywhere close to a (combined) WAN circuit rate of 1 Gbps. Therefore, use one (or more) Fast Ethernet connection on the distribution-layer software inventory application to connect to the WAG so that not only is the aggregate traffic sent to the WAG limited (in 100 Mbps increments), but (because congestion points now are pulled back into the Catalyst switch, thus forcing queuing to engage on the FE switch port) the traffic also will be queued correctly within these limits (of 100 Mbps increments).

For example, a WAN aggregation router is supporting two DS3 WAN connections (totaling 90 Mbps of WAN circuit capacity). In this case, the distribution-layer switch port connecting to the WAG should be Fast Ethernet. Then, if more than 100 Mbps of traffic attempts to traverse the WAN, the Catalyst switch will engage queuing on the switch port and aggressively drop flows according to the defined application hierarchies. Only 100 Mbps of correctly queued traffic will ever be handed off to the WAG.
