The SNA DLC Services MIB Working Group is chartered to define a set of managed objects for the SDLC and LLC-2 data link controls for SNA networks. These objects will be the minimum necessary to provide the ability to monitor and control those devices, providing fault, configuration, and performance management, and will be consistent with the SNMP framework and existing SNMP standards. The working group will consider existing enterprise-specific MIB modules that define objects which support management of these devices. The group may choose to consider any work done by the IEEE in the area of managed object definition for LLC-2. It will also make sure that its work is aligned with the SNA NAU Services MIB Working Group, due to the close relationship between the devices being worked on by the two groups. The working group recognizes that managed objects for other SNA data link controls and related components (e.g., QLLC, System/370 Channel, Data Link Switching, and ESCON) may need to be identified in the future. These objects are out of scope for the current charter; however, once the group completes its charter, a new charter identifying some or all of these components may be considered.
