VLANs and VLAN tagging are supported on both IPv4 and IPv6 transports. This feature is currently supported on the following Infoblox appliances: Trinzic 1410, 1415, 1420, 1425, 2210, 2215, 2220, 2225, Infoblox-4010, Infoblox-4030-Rev1, Infoblox-4030-Rev2, Infoblox-4030-10G, PT-1400, PT-1405, PT-2200, PT-2205, PT-4000, PT-4000-10GE, TE-1410, TE-1420, TE-1415, and TE-1425. VLAN tagging is not supported on TE-100, TE-810, TE-815, TE-820, and TE-825. For more information about VLAN support for an Infoblox-4030 appliance, refer to the DNS Cache Acceleration Application Guide. For information about these appliances, refer to the respective installation guides on the Infoblox Support web site at http://www.infoblox.com/support.
Currently, only the DNS service can listen on specific VLAN interfaces. The DHCP service listens only on the primary VLAN interface (tagged or untagged). You can also specify VLANs as the source port for sending DNS queries and notify messages. For information about how to configure these, see Specifying Port Settings for DNS.
Additional VLAN support is available exclusively for discovery on the following Network Insight appliances: ND-1400, ND-1405, ND-2200, ND-2205, ND-4000, ND-V1400, ND-V1405, ND-V2200, and ND-V2205. Binding other services on
the VLAN interfaces of the Network Insight appliances is not supported.

You can implement DiffServ (Differentiated Services) on the appliance by configuring the DSCP (Differentiated Services Code Point) value. DiffServ is a scalable and class-based mechanism that provides relative priorities to the type of services on your network. It can provide low latency for critical network traffic while providing simple
best-effort service for non-critical services. The Infoblox DSCP implementation fully conforms to RFC 2475. For more information about DiffServ, refer to RFC 2475, An Architecture for Differentiated Services.
In IPv4 and IPv6 headers, DiffServ uses the DS (Differentiated Services) field for packet classification purposes. The DS field defines the layout of the ToS (Type of Services) octet in IPv4 and the Traffic Class octet in IPv6. The first six bits of the DS field are used as the DSCP value, which determines the PHBs (per-hope behaviors) on DiffServ compliant nodes and enables priorities of services to be assigned to network traffic. For more information about the DS field, refer to RFC 2474, Definition of the Differentiated Services Field (DS Field) in the IPv4 and IPv6 Headers.
When you configure the DSCP value for DiffServ, the appliance sets priorities for all outgoing IP traffic. It implements QoS (quality of service) rules so you can effectively classify and manage your critical network traffic. To ensure that core network services, such as DNS services, continue to operate in the event of network traffic congestion, you can set the DSCP value for the entire Grid and override it at the member level. Note that on an appliance, all outgoing IP traffic on all interfaces uses the same DSCP value.
DSCP is supported on both IPv4 and IPv6 transports and the DSCP value for both IPv4 and IPv6 transports must be the same. This feature is currently supported on the following Infoblox appliances: Trinzic 2210, 2215, 2220, 2225, Infoblox-4010, Infoblox-4030, Infoblox-4030-10GE, PT-1400, PT-1405, PT-2200, PT-2205, PT-4000, PT-4000-10GE, TE-1410, TE-1420, TE-1415, TE-1425, and TE-14254015. For information about these appliances, refer to the respective installation guides on the Infoblox Support web site at http://www.infoblox.com/support.

This section provides tables that detail the port usage and source and destination ports for different services, depending on your Grid configuration.
bookmark904 displays the type of traffic per port for both Grid and independent deployments. For a more detailed list of the different types of traffic, see bookmark906.
