Deployment Mode For each virtual router, you select the deployment mode: ■ Sniffer – In an out-of-path, sniffer mode deployment, the IDP appliance can detect attacks but can take only limited action. You connect the IDP traffic interfaces to a mirrored port of a network hub or switch.
Figure 6: Internal Bypass When the IDP operating system resumes healthy operations, it sends a reset signal to the traffic interfaces, and the interfaces resume normal operation. NOTE: All copper port traffic interfaces support internal bypass. Some, but not all, fiber port traffic interfaces support internal bypass.
External Bypass The External Bypass setting supports third-party external bypass units. When the IDP appliance is turned on and available, it sends NetScreen Redundancy Protocol (NSRP) heartbeats to the external bypass unit. When the NSRP packets flow, the external bypass unit allows connections to proceed through the IDP appliance.
When PPM is enabled, a PPM daemon monitors the health of IDP traffic interfaces belonging to the same virtual router. If a traffic interface loses link, the PPM process turns off any associated network interfaces in the same virtual router so that other network devices detect that the virtual router is down and route around it.
■ If you enable Layer 2 bypass, the interfaces pass through IPv6, internetwork packet exchange (IPX), Cisco Discovery Protocol (CDP), and interior gateway routing protocol (IGRP). ■ If you enable internal bypass, the interfaces do not pass through NetScreen Redundancy Protocol (NSRP) packets even if Layer 2 bypass is enabled.
