Infoblox: Import DHCP from Windows DHCP when using VoIP

January 12th, 2011 | No Comments | Posted in Infoblox

When importing DHCP scopes and settings from a Microsoft DHCP with the Data Import Wizard, it’s important to verify that the DHCP options are correct.

This is especially important when dealing with IP telephones.

Recently, when I helped import some DHCP data from a Microsoft DHCP server, the Data Import Wizard changed the call server option (Option 128 for Nortel) from “String” to “Text”. You might guess the result.

If you more information on the correct syntax for “Call Server Information” (Option 128) for Nortel IP telephones, use the following blog post by Michael McNamara as a reference.

Infoblox NIOS 6.0 and older appliances

January 10th, 2011 | No Comments | Posted in Infoblox

Just a note, if you are stuck with one of the following models:
IB: -250, -500, -1000, -1200, -550, -1050, -1550, and -2000 you will not be able to upgrade to 6.0.

You can check if your appliance(s) is/are compatible by running the following cli command:

show upgrade_compatible 6.0

Running it will look something like this:

Infoblox > show upgrade_compatible 6.0
Hardware Type(model) Node IP Status
IB-1050 192.168.150.2 Not Compatible
The grid is not compatible with 6.0 release.
Infoblox >

If you try to upgrade, you will get the following error message, when you try to distribute the image:
2011-01-10 09:41:10 UTC,”syslog”,”CRITICAL”,”logger[24930]”,”Use CLI: show upgrade_compatible”
2011-01-10 09:41:10 UTC,”syslog”,”CRITICAL”,”logger[24928]”,”Grid not compatible with 6.0 release”
