Use MIBs

This chapter describes how to determine which Management Information Bases (MIBs) are supported by a Juniper Networks release, and how to query enterprise-specific and standard MIBs to retrieve management information for the various hardware and software components of a Juniper Networks router. (See Table 39.)
