This article contains information about deploying NetScaler appliances in a high availability setup in two arm mode having multiple subnets with VLAN IDs.

Requirements

• Both the NetScaler appliances must be on the same NetScaler software release version and have the same hardware platform.
• Configure the appliances in a high availability setup. Ensure that both the appliances are communicating to each other. Refer to CTX116748 - How to Set Up a High Availability Pair on NetScaler.

Background

In this scenario, you have a requirement that NetScaler appliance must communicate with four VLANs such as 200, 201, 202, and 400, and the mode of communication must be in two arm mode.

The IP range for communication of VLAN 200, 201, 202, and 400 are 192.168.200.0/24,192.168.300.0/24,192.168.400.0/24, and 172.17.154.0/24 respectively:

• Internal VLAN200 / 192.168.200.x
• Internal VLAN201 / 192.168.300.x
• Internal VLAN202 / 192.168.400.x
• DMZ VLAN400 / 172.17.154.x

Instructions

To deploy NetScaler appliances in a high availability setup in two arm mode when having multiple subnets with VLAN IDs, complete the following procedure:

1. Run the following commands to enable the interfaces which you are planning to use and disable the unused ports on the primary and secondary appliances:
   enable interface 1/1
   enable interface 1/2
   enable interface 1/3
   enable interface 1/4
   disable interface 1/5

2. Run the following commands to bind the VLANs to the interface on the primary and the secondary appliance:
   add ns ip 192.168.200.10 255.255.255.0 -type SNIP
   add vlan 200
   bind vlan 200 -ifnum 1/1
   bind vlan 200 -IPAddress 192.168.200.10 255.255.255.0
   add ns ip 192.168.300.10 255.255.255.0 -type SNIP
   add vlan 201
   bind vlan 201 -ifnum 1/2
   bind vlan 201 -IPAddress 192.168.300.10 255.255.255.0
   add ns ip 192.168.400.10 255.255.255.0 -type SNIP
   add vlan 202
   bind vlan 202 -ifnum 1/3
   bind vlan 202 -IPAddress 192.168.400.10 255.255.255.0
   add ns ip 172.17.154.10 255.255.255.0 -type SNIP
   add vlan 400
   bind vlan 400 -ifnum 1/4
   bind vlan 400 -IPAddress 172.17.154.10 255.255.255.0
