Issue with setting up fast L4 virtual servers via Java

We want to set up a https virtual server with the following characteristics:

 

 

- service port 443

 

- Protocol: tcp

 

- Type: performance (Layer 4)

 

- source address default persistence profile

 

- SNAT automap

 

 

Our code (below) works, except that the virtual server is configured as a standard virtual server. I would greatly appreciate it if you could glance at this code…Do you see anything here that prevents it from being set up as a fast L4?

 

 

 

public void createHttpsVirtualServer(final String name, final String ip, final long port, final String poolName) throws LoadBalancerException {

 

 

CommonVirtualServerDefinition vsDef = new CommonVirtualServerDefinition(name, ip, port, CommonProtocolType.PROTOCOL_TCP);

 

 

final CommonVirtualServerDefinition[] definitions = new CommonVirtualServerDefinition[]{vsDef};

 

 

final String[] wildmasks = new String[]{"255.255.255.255"};

 

 

final LocalLBVirtualServerVirtualServerResource resource = new LocalLBVirtualServerVirtualServerResource(LocalLBVirtualServerVirtualServerType.RESOURCE_TYPE_FAST_L4, poolName);

 

 

final LocalLBVirtualServerVirtualServerResource[] resources = new LocalLBVirtualServerVirtualServerResource[]{resource};

 

 

final LocalLBVirtualServerVirtualServerType[] serverTypes = new LocalLBVirtualServerVirtualServerType[]{LocalLBVirtualServerVirtualServerType.RESOURCE_TYPE_FAST_L4};

 

 

LocalLBVirtualServerVirtualServerPersistence profile = new LocalLBVirtualServerVirtualServerPersistence();

 

 

profile.setProfile_name("fastL4");

 

 

final LocalLBVirtualServerVirtualServerProfile[][] profiles = new LocalLBVirtualServerVirtualServerProfile[][]{{}};

 

 

try {

 

getLbInterface().getLocalLBVirtualServer().create(definitions, wildmasks, resources, profiles);

 

} catch (Exception ex) { throw new LoadBalancerException(ex);

 

}

 

}

    In order to create a fastL4 virtual, you need to have the "fastL4" profile attached to it. Right now you are not passing in any profiles in your "profiles" variable. Try passing in a profile with the context of "PROFILE_CONTEXT_TYPE_ALL" and name of "fastL4" in the [0][0] element of the profiles variable. I don't have any java code at the moment to pass along, but here's a PowerShell script that will do it with the iControl Snapin setup.

     

     

    update these variables with your configuration

     

    $name = "testvip";

     

    $ip = "99.99.99.99";

     

    $port = 80;

     

    $pool = "pool_name_goes_here";

     

     

    $definition = New-Object -TypeName iControl.CommonVirtualServerDefinition;

     

    $definition.name = $name;

     

    $definition.address = $ip;

     

    $definition.port = $port;

     

    $definition.protocol = "PROTOCOL_TCP";

     

    $definitions = (, $definition);

     

     

     

    $wildmasks = (, "255.255.255.255");

     

     

     

    $resource = New-Object -TypeName iControl.LocalLBVirtualServerVirtualServerResource;

     

    $resource.type = "RESOURCE_TYPE_FAST_L4";

     

    $resource.default_pool_name = $pool;

     

    $resources = (, $resource);

     

     

     

    this is the piece you are missing...

     

    $profile = New-Object -TypeName iControl.LocalLBVirtualServerVirtualServerProfile;

     

    $profile.profile_context = "PROFILE_CONTEXT_TYPE_ALL";

     

    $profile.profile_name = "fastL4";

     

    $profileA = (, $profile);

     

    $profileAofA = (, $profileA);

     

     

    Write-Host "Creating Virtual Server `"$name`"...";

     

    (Get-F5.iControl).LocalLBVirtualServer.create(

     

    $definitions,

     

    $wildmasks,

     

    $resources,

     

    $profileAofA

     

    );

     

     

     

    Hope this helps...
