Chapter 21 Annex Manager and SNMP
Annex Manager User Guide
Part 4 Control and Status Commands
The SMI (Structure of Management Information) uses the ISO standard
ASN.1 (Abstract Syntax Notation One) to define a method for describing
a hierarchical name space for managed information. Each object has:
• A name (also referred to as an Object Identifier (OID)).
• A syntax and an encoding. In addition to the basic integer and
octet string data types, several special types are defined (e.g,
IP
Address
,
Network Address
,
Counter
,
Gauge
,
TimeTicks
). RFC 1212
(Concise MIB Definitions) is an easier-to-read form used in
most standard MIBs today. It is used to define the Annex
private enterprise MIB.
Trap Hosts and Traps
The Annex employs two methods to define the host addresses it uses when
generating SNMP trap messages.
• The first method defines up to ten static trap receivers in the
configuration file using the snmp trap host syntax. For detailed
information about the SNMP trap host syntax, see the Remote
Annex Administrator’s Guide for UNIX.
• The second method loads the trap hosts (if any) from the
configuration file into the Trap Host Table (i.e., the
anxTrapHostTable object in the proprietary MIB). You can
then modify this table by adding or deleting trap hosts.
However, the changes you make directly through the table are
lost when the Annex reboots. If you need to make permanent
changes, you must use the Annex configuration file.
Annex Manager Release 2.3 does not support access to the Trap Host
Table. You cannot display or change this table through Annex
Manager.
