Monitoring Pseudowires

This chapter describes how you can monitor the health of a pseudowire. Using the health monitoring feature, you can display important attributes of a pseudowire, configure the devices in JUNOScope with a trap destination, and create a template of the RMON events for which the traps are generated.

A trap is a one-way message that is sent from a network element, such as a router or a switch, to its network management system, such as JUNOScope. JUNOScope is notified about each object on its managed devices without having to request information. SNMP trap destinations define the hosts that will receive the SNMP traps that are generated by the trap group when certain conditions apply. You can create a trap destination model or template that contains default parameters for trap destinations and then associate this model with one or more virtual routers. These parameters are used across many virtual routers over multiple devices. The default parameters you select should be appropriate to the needs of the virtual routers with which you are associating the trap destination. A virtual router on a device is capable of configuring up to eight trap destination hosts.

SNMP makes use of Remote Monitoring (RMON) enhancements to the management information base (MIB) structure to monitor traffic and set an alarm when a certain condition occurs. In the standard MIB, the network device had to be queried to obtain information. RMON is proactive and can set alarms on a variety of traffic conditions, including specific types of errors.

You must have read-only, read-write, and superuser permissions to monitor the health of pseudowires.
