## Other Network Considerations

### SNMP

The 9600 Series IP Telephones are fully compatible with SNMPv2c and with Structure of Management Information Version 2 (SMIv2). The telephones 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 read-only Custom MIB. Read-only means that the values therein cannot be changed externally by means of network management tools.

You can restrict which IP addresses the telephone accepts SNMP queries from. You can also customize your community string with system values SNMPADD and SNMPSTRING, respectively. For more information, see Chapter 5: Server Administration and Table 7: 9600 Series IP Telephone Customizable System Parameters.

To find more information about SNMP and MIBs, see the IETF references listed in
Appendix B: Related Documentation. The Avaya Custom MIB for the 9600 Series IP Telephones is available for download in *.txt format on the Avaya support Web site at
