Cabling the Appliance to a Network
Use one or more Category 5/6 Ethernet cables to connect the appliance to the network.
Connect an Ethernet cable from the LAN1 port on the appliance to your network switch or router.
( ) If you want to connect your appliance for HA (high availability), connect the HA ports on both Trinzic TE-2215 and TE-2225 appliances only
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.

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 in the Modifying Ethernet Port Settings Infoblox NIOS Administrat
for the steps to resolve the problem.or Guide
( ) To ensure that VRRP (Virtual Router Redundancy Protocol) works properly, configure Applies only to Trinzic TE-2215 and TE-2225 appliances
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
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 2205 Series Appliance
