To monitor a bidirectional IP network path

Steps


1	Choose Tools→Route Analysis→Path and Prefix Monitoring from the NFM-P main menu. The Path and Prefix Monitoring form opens.
2	Click on the Create button and choose Bidirectional IP Path Monitor. The Bidirectional IP Path Monitor (Create) form opens with the General tab displayed. Note: Alternatively, you can create a bidirectional IP network path monitor from an existing unidirectional path monitor. See To create a bidirectional IP path monitor from a unidirectional IP path monitor . You can also create a bidirectional IP path monitor from the topology map. See To create an IP path monitor between two routers on a topology map for information.
3	Configure the parameters: Name Description Monitor State
4	Configure the Endpoint A IP parameter or use the Select button to choose a router.
5	Configure the Endpoint A Length parameter.
6	Configure the Endpoint A IP parameter or use the Select button to choose a router.
7	Configure the Endpoint A Length parameter.
8	Click on the Apply button to save the configuration. The CPAM monitors the path only if the Monitor State is set to Up. Unidirectional paths are created, if required, or existing unidirectional paths with matching endpoints are associated with the new bidirectional path.
9	Click on the Path History tab button to view historical paths of the two unidirectional paths. You can sort the list by the time at which the paths were rerouted, created, or removed. Note: You can click on the Capture Path button to perform an immediate path capture. See To manually run an OAM diagnostic on an IP, LSP, or P2MP path monitor Chapter 13, OAM diagnostics for information about how to run an OAM test.
10	Click on the Service Tunnels tab button to view monitored GRE and LDP SDP tunnels in both directions.
11	Click on the Services tab button to view services that use the monitored IP paths.
12	Click on the Composite Services tab button to view composite services that use the monitored IP paths.
13	Close the Bidirectional IP Path Monitor (Create) form.
14	Close the Path and Prefix Monitoring form. End of steps
