Top Talkers

Just as in standard Observer, Top Talkers shows the IP and MAC address of stations on your network sorted by volume of traffic generated and received. In WAN Observer, the MAC Address tab shows DLCIs sorted by volume of traffic. Also, the sorting and charting statistical criteria (such as percentage of packets, packets per second, etc.) that apply to WAN is a subset of those available for standard network analysis.

WAN Filtering

In addition to the standard Observer packet filtering rules (station address, pattern matching, etc.), there are two WAN-specific filtering rules available for use with WAN probes:

•DLCI Address, which lets you enter the number of the DLCI address you wish include or exclude.

•WAN Conditions, which let you include or exclude frames based on flow direction, forward and backward congestion, and discard eligibility.

To create a WAN filter rule, choose Actions->Filter Setup for Selected Probe. The default filter rule (any address<-->any address) is displayed. Select and right click on the rule to display the popup menu:
