Use one or more Category 5/6 Ethernet cables 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. (Infoblox Trinzic TE-4015 and TE-4025 appliances only) 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

Appliance–Network Connectivity

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.

Occasionally, the Infoblox appliances may fail to auto-negotiate that speed and type, and instead connect at lower speeds of either 100 or 10 Mbps using potentially mismatched full- and half-duplex transmissions. If this occurs, begin by determining whether there is a firmware upgrade available for the switch. If so, apply the firmware upgrade to the switch and test the connection. If that does not resolve the issue, manually set the ports on the Infoblox appliance and on the switch to make 1000-Mbps full-duplex connections. See the section Modifying Ethernet Port Settings in the Infoblox NIOS Administrator Guide for the steps to resolve the problem.

  1. (Applies only to Infoblox Trinzic TE-4015 and TE-4025 appliances) 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
    • 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

Use the Grid Manager from a management system to access, set up and administer the Infoblox appliance. For management system requirements and access instructions, see Accessing the Infoblox 4005 Series Appliance.
