Cabling the Appliance to a Network

Use one or more Category 5/6 Ethernet cables to connect the Infoblox-4010 appliance to the network.

1. Connect an Ethernet cable from the LAN1 port on the Infoblox-4010 to the network switch or router, as indicated in Figure 17.
2. To connect the Infoblox-4010 appliance for HA (high availability, available only when you have two

Infoblox-4010 appliances for redundant operation), 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.
Figure 17 Cabling a Single Appliance and an HA Pair to a Network

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.

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 Infoblox NIOS Administrator Guide for steps to resolve the problem.
The Network Insight ND-4000 appliance does not support HA (high availability).

1. (Infoblox-4010 only) To ensure that VRRP (Virtual Router Redundancy Protocol) works properly, configure the following settings at the port level for all the connecting switch ports (LAN1, LAN2 and HA where applicable):
   • Spanning Tree Protocol: Disable. For vendor specific information, search for "HA" in the Infoblox Knowledge Base system at https://support.infoblox.com/
   • 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
2. 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 29.
