1. Introduction These Application Notes describe the configuration steps required for Infoblox DNSone to provide DHCP and TFTP services in an Avaya IP Office IP Telephony environment. The Infoblox DNSone module delivers integrated DNS, DHCP and TFTP services for Infoblox network identity appliances. It may be used as an integrated DNS/DHCP/TFTP server, external authoritative name server, forwarder, secondary server, caching-only name server, or DHCPonly server. Configuration of the DNSone module is done through a web-based graphical user interface. The DNSone module also provides security and reliability features. It minimizes unauthorized access by blocking unnecessary ports and not providing general user accounts (multiple administrative accounts are allowed). For increased reliability, two DNSone appliances may be deployed in a High Availability or DHCP Failover configuration. The configuration in Figure 1 shows a network consisting of the Avaya IP412 Office, Avaya 4600 and 5600 IP Telephones and Infoblox DNSone connected to an Avaya C363T-PWR Stackable Switch. The Avaya IP Telephones registered to the Avaya IP412 Office. The tested configuration is shown in Figure 1. 2 of 33

7. Interoperability Compliance Testing The interoperability compliance testing focused on verifying the Infoblox DNSone properly provided DHCP and TFTP services for Avaya 4600 and 5600 IP Telephones in an Avaya IP Office IP Telephony Infrastructure. 7.1. General Test Approach The general test approach was to connect different models of the Avaya 4600 and 5600 IP Telephones to different VLAN ports on the Avaya C363T-PWR Stackable Switch and verify that the Avaya 4600 and 5600 IP Telephones successfully receive responses to their DHCP and TFTP requests from the Infoblox DNSone. 7.2. Test Results All executed test cases completed successfully with the observations noted below: TFTP uploads are single file at a time Current implementation of TFTP server on DNSone limits file uploads to a single file at a time. During compliance testing, a special Infoblox admin Perl script was used to download an entire directory s contents rather than one file at a time. At Avaya s request, Infoblox has since created a data import tool that they report really simplifies TFTP file import. The tool can be downloaded from http://www.infoblox.com/import. Sample screen shots of the tool sent by Infoblox can be found in Appendix A. Status: Infoblox reports the TFTP data import tool s functionality will be integrated into the Infoblox browser interface in an upcoming release. Infoblox TFTP logging is not available via the browser interface The Infoblox TFTP server does not provide logging through the standard monitoring logs available via the browser interface to the DNSone. Status: Infoblox reports improvements have been made to their Syslog capabilities to provide more messaging from their TFTP service. This should be available in an upcoming release. 8. Verification Steps The following steps may be used to verify the configuration between the DNSone and the Avaya 4600 and 5600 IP Telephones in an Avaya IP Office IP network. From each subnet/vlan, ping the DNSone and the Avaya IP Office and verify connectivity. In the DNSone browser interface, verify that the address scopes and their associated address ranges and options are specified according to the information listed in Table 1. 27 of 33
Power cycle or reset an Avaya 4600 or 5600 IP Telephone. Verify the Avaya IP Telephone obtains an IP address from the DNSone DHCP server. Verify the Avaya IP Telephone downloads either the 46xxsettings.txt or 46xxupgrade.scr files from the DNSone TFTP server in addition for firmware upgrade or downgrade files as appropriate. After the Avaya IP Telephone acquires configuration information, enter the extension and password when prompted. After the telephone comes up, press MUTE followed by 2337# (ADDR#) and verify that the assigned IP address, subnet mask, call server IP address and port, 802.1q tagging setting, and VLAN ID are correct. Repeat for each Avaya 4600 and 5600 IP Telephone being verified. Verify the Avaya 4600 and 5600 IP Telephones successfully register with the Avaya IP Office and calls can be successfully placed between extensions. To view all DHCP log messages on the DNSone, select the MONITORING tab at the top of the page. In the left hand pane, browse to ID Grid Infoblox 20.1.1.100. 28 of 33
To verify leased IP addresses on the DNSone, select the MONITORING tab at the top of the page then click DHCP in the menu bar under the MONITORING tab. 9.
