Simple Network Management Protocol (SNMP) is a family of standards-based protocols and procedures to allow vendor-independent data network management. Using a simple set of protocol commands, an SNMP-compliant device stores information in standard format in one or more Management Information Bases (MIBs). In general, devices support the standards-specific MIB termed MIB-II. In addition, devices may define one or more “custom MIBs” that contain information about the specifics of the device.
As of Release 1.1, the 4600 Series IP Telephones are fully compatible with SNMPv2c (a later version of SNMP) and with Structure of Management Information Version 2 (SMIv2), although the telephones will respond correctly to queries from entities that comply with earlier versions of SNMP, such as SNMPv1. “Fully compatible” means that the telephones respond to queries directed either at the MIB-II or the Custom MIB. The 4600 Series IP Telephone Custom MIB is read-only (values therein cannot be changed externally via network management tools).
You can restrict which IP addresses the telephone accepts SNMP queries from and you can customize your community string with system values SNMPADD and SNMPSTAT, respectively, as indicated in Chapter 4, , Table 4-5.
More information about SNMP and MIBs can be found in the IETF references listed in Related Documents. The Avaya Custom MIB for the 4600 Series IP Telephones is available for download in *.txt format on the Avaya support website.
