Creating a Load Balancing Virtual Server

Aug 31, 2016

The cache redirection virtual server on the NetScaler appliance can send requests to either a cache server farm, if the request is cacheable, or to the origin server farm if the request is not cacheable.

Each cache server is represented on the appliance by a service, which is bound to a load balancing virtual server that receives requests from the cache redirection virtual server and forwards those requests to the servers.

For details on configuring load balancing virtual servers and other configuration options, see "Load Balancing."

To create a load balancing virtual server by using the command line interface

At the command prompt, type the following commands to create a load balancing virtual server and verify the configuration:

  • add lb vserver <name> <serviceType> [<IPAddress>] [<port>]
  • show lb vserver [<name>]

Example

 
> add lb vserver Vserver-LB-CR HTTP 10.102.20.30 80 
 Done 
> show lb vserver Vserver-LB-CR 
        Vserver-LB-CR (10.102.20.30:80) - HTTP  Type: ADDRESS 
        State: DOWN 
        Last state change was at Fri Jul  2 08:47:52 2010 
        Time since last state change: 0 days, 00:00:08.470 
        Effective State: DOWN 
        Client Idle Timeout: 180 sec 
        Down state flush: ENABLED 
        Disable Primary Vserver On Down : DISABLED 
        Port Rewrite : DISABLED 
        No. of Bound Services :  0 (Total)       0 (Active) 
        Configured Method: LEASTCONNECTION 
        Mode: IP 
        Persistence: NONE 
        Vserver IP and Port insertion: OFF 
        Push: DISABLED  Push VServer: 
        Push Multi Clients: NO 
        Push Label Rule: none

To create a load balancing virtual server by using the configuration utility

  1. Navigate to Traffic Management > Load Balancing > Virtual Servers.
  2. In the details pane, click Add.
  3. In the Create Virtual Server (Load Balancing) dialog box, specify values for the following parameters as shown:

    • Name*-name
    • IP Address*- IPAddress
    • Port*-port

    * A required parameter

  4. In the Protocol* drop down list, select a supported protocol (for example, HTTP). If the virtual server is to receive traffic on a port other than the well-known port for the selected protocol, enter a new value in the Port field.
  5. Click Create, and then click Close. The Load Balancing Virtual Servers pane displays the new virtual server.
