This article describes how to configure the appliances in a high availability setup to communicate in a two-arm configuration with different In some network topologies, administrators enforce a security policy where VLAN traffic through their switching equipment must be tagged, but VLAN 1 is not allowed. The NSVLAN configuration is not always supported to configure the appliances in a high availability setup with a two-arm topology with this type of policy. The following diagram demonstrates this configuration:.

As seen in this scenario, you want a failover to occur if either of the interfaces on the primary appliance fails. For the preceding topology requirement, the following configuration is required:. Therefore, you send that traffic out on the appropriate VLAN with the appropriate tag. Failed to load featured products content, Please try again.

Without the proper VLAN configuration, the NetScaler is unable to determine which interface to use and it can function more like a HUB than a switch or router in these instances it will try to use ALL interfaces for each conversation.

This type of issue can manifest itself in many forms, including performance issues, inability to establish connections, randomly disconnected sessions, and in severe situations, network disruptions seemingly unrelated to the NetScaler itself. Management interfaces on the NetScaler is not designed to handle large volumes of traffic, which may result from network and VLAN misconfigurations triggering the NetScaler to use a management interface for production data traffic.

This situation can be caused by VLAN misconfigurations where the NetScaler transmits on a different interface than the target device would typically use to communicate with the NetScaler often seen in conjunction with MAC moves.

While this situation can be caused by network conditions, it often occurs as a result of VLAN and interface misconfiguration. If you require more than one subnet to be associated with an interface, the subnets must be tagged. MBF is designed primarily for the DSR Direct Server Return mode of the NetScaler, which is rarely used in most environments it is designed to allow traffic to purposely bypass the NetScaler on the return path from the backend servers.

If the NetScalers cannot communicate between native VLANs on any interface, this will lead to HA failovers and possibly a split-brain situation where both NetScalers think they are primary leading to duplicate IP addresses, amongst other things.

The NetScaler does not participate in spanning tree. As such, it is not possible to use spanning tree to provide for interface redundancy when using a NetScaler. Note : If you wish to have link aggregation between multiple physical switches, you must have the switches configured as a virtual switch, using a feature such as Cisco's Switch Stack.

This must be enforced by the enduser through VLAN configuration. The Management interfaces are not designed to handle data traffic, so your network design should take this into account. In many configurations, the default route will be relied-upon for workstation commmunications in an internet scenario. If the default route is on the same subnet as the NSIP this will lead to such traffic using the management interface, which can cause the interface to be overloaded. This can lead to obvious connectivity issues between the instances and SVM and as such, is not recommended.
