An overview of the complete DHCP configuration process is outlined in the following diagram, illustrating the main steps for preparing a NIOS appliance for use. Note that the process for configuring the DHCP server is the same for IPv4 and IPv6 networks, except that failover associations are not supported in IPv6 networks.

# Configuring the Connecting Switch

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 <span style="color: #0000ff">[*https://support.infoblox.com*](https://support.infoblox.com)</span>.
- Trunking: Disable
- EtherChannel: Disable
- IGMP Snooping: Disable
- DHCP Snooping: Disable or Enable Trust Interface


- 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
