Avaya Solution & Interoperability Test Lab Application Notes for Configuring Infoblox DNSone DHCP Failover or High Availability in an Avaya Communication Manager IP Telephony Infrastructure - Issue 1.0 Abstract These Application Notes describe the procedure for configuring Infoblox DNSone for DHCP Failover as well as the procedure for configuring Infoblox DNSone for High Availability in an Avaya Communication Manager IP Telephony Infrastructure.
1. Introduction These Application Notes focus on the steps required for configuring Infoblox DNSone DHCP Failover or High Availability in an Avaya Communication Manager IP Telephony environment. For information on how to configure Infoblox DNSone to deliver DHCP and TFTP services in an Avaya IP Telephony environment, please refer to the Application Notes in references [4], [5], and [6]. The Infoblox DNSone delivers integrated DNS, DHCP and TFTP services for Infoblox network identity appliances.
Figure 1 – Sample DHCP Failover Network Configuration Diagram The configuration in Figure 2 shows a network consisting of the Avaya S8300 Media Server with G700 Media Gateway, Avaya 4600 Series IP Telephones, and two Infoblox DNSone appliances configured as a High Availability pair connected to an Avaya C363T-PWR Stackable Switch. The Avaya IP Telephones registered to the Avaya S8300 Media Server.
Table 1 shows the DHCP Option 176 string settings the Infoblox DNSone DHCP server must provide for the Avaya 4600 IP Telephones to register with Avaya Communication Manager in the sample configurations.
