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).
