Consolidation When the Management Service and the NetScaler Instances are in the Same Network

Jun 13, 2017
A simple type of consolidation case on the SDX appliance is configuration of the Management Service and the NetScaler instances as part of the same network. This use case is applicable if the appliance administrator is also the instance administrator and your organization's compliance requirement does not specify that separate management networks are required for the Management Service and the NSIP addresses of the different instances. The instances can be provisioned in the same network (for management traffic), but the VIP addresses can be configured in different networks (for data traffic), and thus in different security zones.

In the following example, the Management Service and the NetScaler instances are part of the 10.1.1.x. network. Interfaces 0/1 and 0/2 are the management interfaces, 1/1 to 1/8 are 1G data interfaces, and 10/1 to 10/4 are 10G data interfaces. Each instance has its own dedicated physical interface. Therefore, the number of instances is limited to the number of physical interfaces available on the appliance. By default, VLAN filtering is enabled on each interface of the NetScaler SDX appliance, and that restricts the number of VLANs to 32 on a 1G interface and 63 on a 10G interface. VLAN filtering can be enabled and disabled for each interface. Disable VLAN filtering to configure up to 4096 VLANs per interface on each instance. In this example, VLAN filtering is not required because each instance has its own dedicated interface. For more information about VLAN filtering, see VLAN Filtering.

The following figure illustrates the above use case.
