The Frame Relay Service MIB Working Group is chartered to define a set of managed objects which will be useful for customer network management of a provider's Frame Relay Service. The working group will consider existing definitions, including the Frame Relay Forum's work in this area. The objects defined by the working group will be consistent with the SNMP framework. The working group will coordinate with both the Frame Relay Forum, the ATM MIB Working Group, and other relevant groups. The working group is chartered to complete four tasks: a) consider revisions to the FRS MIB (currently published as a Proposed Standard in RFC 1604) in light of implementation experience, changes to the interface MIBs (e.g. IF-MIB, DS1-MIB, DS3-MIB, FR-DTE-MIB, creation of the DS0 and DS0 Bundle MIB modules), and evolution of the relevant non-IETF standards, b) prepare a Recommendation to the Area Director as to the appropriate disposition of the (updated) FRS MIB, i.e. that it be advanced to Draft Standard status or that it cycle at Proposed Status, c) develop a set of managed objects to provide the instrumentation required to manage switched-virtual circuits in a frame-relay environment. d) develop a set of managed objects to provide the instrumentation required to manage connections that terminate on a mixture of ATM and Frame Relay interfaces, i.e. interworked connections. These objects will be the minimum necessary to provide the ability to monitor and control interworked connections and shall use existing definitions (e.g. IF-MIB, FRS-MIB, ATM-MIB, etc.) to instrument the interfaces and the "native" parts of the connections. e) develop a set of managed object for the management of Frame Relay Service Level Definitions. f) consider other closely related future work items. In all cases, the working group will keep the Frame Relay and ATM Forums and the ATM MIB WG informed of its progress and will actively solicit their input. All output of the group will be consistent with the existing SNMPv2c framework and standards, including the SNMPv2c Structure of Management Information (SMI).
