Network Requirements

26 Avaya Agent Deskphone 16CC Administrator Guide

Other Network Considerations

SNMP

Avaya Agent Deskphone 16CC 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.

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 6:

Server Administration and Table 9: Avaya

Agent Deskphone 16CC Customizeable System Parameters.

Note:

Note: SNMP is disabled by default. Administrators must initiate SNMP by setting the

SNMPADD and SNMPSTRING system values appropriately.

For more information about SNMP and MIBs in a SIP environment, see Installing and

Administering SIP Enablement Services (Document Number 03-600768). For general

information about SNMP and MIB, see the IETF Web site listed in Appendix B:

Documentation. The Avaya Custom MIB for the telephones is available for download in *.txt

format on the Avaya support Web site at http://www.avaya.com/support

Registration and Authentication

An Avaya Agent Deskphone 16CC requires an Outboard Proxy SIP (OPS) extension on Avaya

Communication Manager and a login and password on the SES Server to register and

authenticate it. Registration is described in the Initialization process, in Step 4: Telephone and

the SES Server on page 21. For further information, see Installing and Administering SIP

Enablement Services (Document Number 03-600768), available on the Avaya support Web

site, h

Reliability and Performance

All 16CC telephones respond to a ping or traceroute message sent from Avaya Communication

Manager or any other network source. The telephones do not originate a ping or traceroute.

If applicable, the telephones test whether the network Ethernet switch port supports IEEE

802.1D/q tagged frames by ARPing the router with a tagged frame. For more information, see

VLAN Considerations

on page 82. If your LAN environment includes Virtual LANs (VLANs),

your router must respond to ARPs for VLAN tagging to work properly.
