5. When analyzing a WAN link via the Observer Probe Observer runs passively Passive operation guarantees that analysis will not affect the WAN link however it does have some implications when running Observer Because there is no link over which the Probe system can transmit frames on the link the following features are unavailable e Traffic Generation e Collision Test Running Observer Software with the WAN Probe 30 e Efficiency History e Replay Packet Capture Analyzing a WAN Link with Observer In general the WAN analysis works much like Ethernet analysis One difference is that when appropriate Observer identifies WAN links by their Data Link Connection Identifier DLCI rather than by MAC address as is done with standard protocol analysis In addition many WAN statistical modes break out the data by DCE DTE and summary to reflect the full duplex nature of WAN links Modes unrelated to WAN analysis are greyed out and unavailable The following sections describe how the available Observer modes operate to analyze a WAN link Discover Network Names To access this mode choose Tools gt Discover Network Names Discover Network Names mode will show DLCIs instead of MAC addresses You can also define the Committed Information Rate for each DLCI you are monitoring with WAN Observer Setting the Committed Information Rate CIR for a DLCI The Committed Information Rate defines the guaranteed bandwidth for a
