5. Structure of the MIB Module

The CIRCUIT-IF-MIB consists of the following components:

• ciCircuitTable

• ciIfMapTable

Refer to the compliance statement defined within for a definition of what objects MUST be implemented.

5.1. ciCircuitTable

The ciCircuitTable is the central control table for operations of the Circuit Interfaces MIB. It provides a means of mapping a circuit to its ifIndex as well as forcing the insertion of an ifIndex into the ifTable. The agent is responsible for managing the ifIndex itself such that no device dependent indexing scheme is violated.

A row in this table MUST exist in order for a row to exist in any other table in this MIB module.

5.2. ciIfMapTable

This table maps the ifIndex back to the circuit that it is associated with.
