IS-IS MIB objects that are defined in RFC 1195

Network Protocol Manager for IS-IS supports SNMPv1, v2c, and v3 for the IS-IS MIB objects that are defined in RFC 1195. It does not receive or process SNMP traps.

Because the IS-IS MIB is used by Juniper devices but not by Cisco devices, Network Protocol Manager for IS-IS uses:

• SNMP discovery and SNMP polling to discover and monitor the IS-IS topology for Juniper devices.

• CLI discovery and CLI polling to discover and monitor the IS-IS topology for Cisco devices.

  The CLI commands that are invoked for IS-IS discovery are identified in the Network Protocol Manager Discovery Guide Supplement , and the CLI commands that are invoked for IS-IS monitoring are described in “CLI commands for IS-IS monitoring” on page 166.

  For Juniper devices, Network Protocol Manager for IS-IS reads the IS-IS MIB objects that are identified in the Network Protocol Manager Discovery Guide Supplement to discover the following IS-IS objects:

• IS-IS areas

• IS-IS services

• IS-IS networks

• IS-IS interfaces

• IS-IS neighbor endpoints

• IS-IS adjacencies

  Network Protocol Manager for IS-IS then proceeds to monitor the discovered IS-IS objects by polling the IS-IS MIBs on the managed devices.
