What is VIP on NetScaler VPX?

Answer

Answer

After Netscaler VPX is provisioned, there are three IP addresses that are configured on the system by default: 1 NetScalter IP (NSIP), 1 private Subnet IP (SNIP), 1 public SNIP. The following screen shot shows these three IP addresses:

Alternatively, you can use the show ns ip command to obtain this information.

• NetScaler IP (NSIP) is the address where you access the machine for management purposes.
• Subnet IP (SNIP) is used for server side connections and will be used to route traffic that is destined for the VIP.
• Virtual IP (VIP) is the address of a virtual server to which end users will connect and through which they will eventually be authenticated.

NetScaler VPX is a virtual server instance (VSI) that allows only native VLAN where the NetScaler is located.
Note: VLAN trunking is not supported.

Normally, a VIP should be ordered with a separate subnet to a primary subnet while ordering a NetScaler VPX or any time after provision. You can order a private VIP only after provision. When you order a VIP after provision, you can generate a support ticket to request that the VIPs are routed to the SNIP.

If you have a VIP ordered with 168.1.114.66/31 and 10.118.188.32/30 and routed to SNIP on the NetScaler machine, you can see that IP blocks routed to SNIP on VLAN page and Device Details on your customer Portal. See the following screen shots:

Also, you need to add the VIPs to the NetScaler VPX. Go to System > Network > IPs and click Add. See the following screen shot for a view of the screen:

As shown in the following screen shot, you can test the VIP is accessible by running the ping command:
