APPENDIX B SMARTCELL 6A000 AND SNMP

This appendix briefly describes SNMP support and the MIB files provided (on diskette) with the SmartCell 6A000 switch.

MIB files are defined according to the following:

MIB II (RFC 1213)

Interface Table MIB (RFC 1573)

AToM MIB (RFC 1695)

AToM2 MIB (pre-standard)

LANE MIB (ATM Forum)

UNI 3.0/3.1 ILMI MIB (ATM Forum)

IP over ATM MIB (pre-standard)

IISP MIB

SmartCell 6A000 Switch MIBs (proprietary)

Note Along with the MIBs, the diskette also contains a README file and the release notes.

B.1 INTERNET MIB HIERARCHY

The MIB structure is logically represented by a tree hierarchy (see Figure B-1). The root of the tree is unnamed and splits into three main branches: Consultative Committee for International Telegraph and Telephone (CCITT), International Organization for Standardization (ISO), and joint ISO/CCITT.

These branches and those that fall below each category have short text strings and integers to identify them. Text strings describe object names, while integers allow computer software to create compact, encoded representations of the names. For example, the ZeitNet MIB variable znIpAtmClient is an object name (denoted by number 1,) which is listed at the end of its object identifier number 1.3.6.1.4.1.1295.2.200.1. See the MIB listings later in this appendix for the exact location of this object.

The object identifier in the Internet MIB hierarchy is the sequence of numeric labels on the nodes along a path from the root to the object. The Internet standard for MIB II is represented by the object identifier 1.3.6.1.2.1. It also can be expressed as iso.org.dod.internet.mgmt.mib (see Figure B-1).
