SNMP Support

MIBs

 

 

Introduction

 

In a TCP/IP-based network, each device maintains a set of variables

 

describing its state. In Simple Network Management Protocol (SNMP), these

 

variables are known as objects, but these objects do not hold the same

 

meaning as those within an object-oriented programming architecture.

 

SNMP objects contain information about their state without any methods,

 

other than the ability to read and write their values. A collection of SNMP

 

objects are known as a Management Information Base (MIB).

 

As networks are built, they normally use several MIBs to describe the various

 

structures within the overall architecture. It is more common for developers to

 

use public MIBs for the non-proprietary components of their system and to

 

build their own for the proprietary components.

Public MIBs

 

The VOCAL system supports the following public MIBs:

 

RFC 1213 - MIB II

 

Network Services Monitoring MIB

 

VOCAL supports a subset of the network services monitoring MIBs defined

 

in RFC 2788. This includes the minimum identifiers of applications for use in

 

other MIBs as indexes.

 

For more information refer to this file in the Linux directory: /usr/local/vocal/

 

proxies/netMgnt/NETWORK-SERVICES-MIB.txt.

 

SIP MIBs

 

VOCAL supports the initial version of Session Initiation Protocol (SIP) MIB

 

dated July 2000 (draft-ieft-sip.mib-01.txt). The MIB is temporarily located

 

under enterprise.vovida.vovidaTemporary until the MIB is assigned a

 

permanent location by IANA. For more information refer to /usr/local/vocal/

 

proxies/netMgnt directory for these SIP MIBs:

 

SIP-COMMON-MIB.txt

 

SIP-MIB-SMI.txt

 

SIP-REGISTRAR-MIB.txt

 

SIP-SERVER-MIB.txt

 

SIP-TC.txt

 

SIP-UA-MIB.txt

UCD Enterprise MIB

VOCAL supports and implements the UCD Enterprise MIBs. For additional information, refer to this web site:
