Measures reported by JexRedundentTest

The Routing Engine runs the Junos OS. Software processes that run on the Routing Engine maintain the routing tables, manage the routing protocols used on the router, control the router interfaces, control some chassis components, and provide the interface for system management and user access to the router.

You can install one or two Routing Engines in the router. Each Routing Engine must be installed directly into an SCB. A USB port on the Routing Engine accepts a USB memory device that allows you to load Junos OS. The Routing Engines install into the front of the chassis in vertical slots directly into the SCBs labeled 0 and 1. If two Routing Engines are installed, one functions as the master and the other acts as the backup. If the master Routing Engine fails or is removed and the backup is configured appropriately, the backup takes over as the master.

This test reports the mode of each routing engine available in the Juniper EX Switch.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation

Measure Value Numeric Value
Unknown 1
Master 2
Backup 3
Disabled 4

Note:

This measure reports the Measure Values listed in the table above to indicate the mode of this routing engine. However, in the graph of this measure, the mode of the routing engine is indicated using only the Numeric Values listed in the above table.
