Infoblox Installation Guide

Cabling the Appliance to a Network

Use the Ethernet cables that were shipped with the product to connect the appliance to the network.

1.

Connect an Ethernet cable from the LAN1 port on the appliance to your network switch or router.

2.

If you want to connect your appliance for HA (high availability), connect the HA ports on both appliances to a 
switch on your network. The VIP (Virtual IP), LAN1, and HA port addresses must be on the same subnet and 
must be unique for that subnet.

Cabling a Single Appliance and an HA Pair to a Network

Note: 

By default, an Infoblox appliance automatically negotiates the optimal connection speed and 

transmission type (full or half duplex) on the physical links between its LAN1, LAN2, HA, and MGMT ports and 
the Ethernet ports on a connecting switch. If the two appliances fail to auto-negotiate the optimal settings, see 
the 

NIOS Administrator Guide

 for steps you can take to resolve the problem.

3.

To ensure that VRRP (Virtual Router Redundancy Protocol) works properly, configure the following settings at 
the port level for all the connecting switch ports (HA, LAN1, and LAN2): 

—

Spanning Tree Protocol: Disable. For vendor specific information, search for “HA” in the Infoblox 
Knowledge Base system at 

http://www.infoblox.com/en/support/support-center-login.html

—

Trunking: Disable

—

EtherChannel: Disable

—

IGMP Snooping: Disable

—

Port Channeling: Disable

—

Speed and Duplex settings: Match these settings on both the Infoblox appliance and switch

—

Disable other dynamic and proprietary protocols that might interrupt the forwarding of packets

4.

Use the Infoblox GUI to access the Infoblox appliance from a management system. Through the Infoblox GUI, 
you can set up and administer the appliance. For management system requirements and access instructions, 
see 

Accessing the Appliance

 on page 21.

When cabling a single Infoblox appliance to the 
network, connect an Ethernet cable from the LAN1 port 
on the appliance to a switch or router. 

When cabling a pair of Infoblox appliances to the 
network for high availability, connect Ethernet cables 
from the LAN1 and HA ports on each appliance to a 
switch or router.
