10. Document Number PXE200-3.10.10-08 10 Operation PacketExpert™ - IPLinkSim™ can be installed between two LAN segments as shown in the diagram. PacketExpert™ can be configured as a Bridge to forward frames between the connected networks/end points.

11. Document Number PXE200-3.10.10-08 11 Bypass Emulation Bridge Mode Configuration Emulation Bypass option allows the ARP/Multicast frames to either bypass the emulation (and sent directly to the output port of the link) or to be included as part of the WAN traffic emulated. ARP/Multicast frames are bypassing emulation

12. Document Number PXE200-3.10.10-08 12 Link Emulation PacketExpert™ IPLinkSim emulates a bi-directional WAN link between the ports 2 and 3. Each direction acts as a separate and independent WAN Link. Each link (P2 -> P3) and (P3 -> P2) can be configured independently for all the link emulation characteristics. IPLinkSim™
