Configuring the Instance for Connection Migration

Sep 09, 2014
In your network setup, if you expect connection migration between the routers, then you must configure the layer 4 parameters and make changes to the VLAN configurations, appropriately.
Configure Layer 4 Parameters
If you have two routers and expect connection migration between the routers, you must configure layer 4 parameters on the NetScaler instance.
To configure layer 4 parameters from the configuration utility
  1. Navigate to the System > Network page.
  2. Click the Configure Layer 2 Parameter link, as shown in the following figure.

  3. In the Configure Layer 4 Parameter dialog box, select the Vlan from the L2 Connection Method list, as shown in the following figure.

  4. Click OK.
To bind the subnet IP address to VLAN of data interface by using the command line interface, run the following command
> set L4Param –l2connMethod vlan
Configuring VLANs for Connection Migration
If the network has two links and connected to interfaces that are bound to different VLANs, then you must bind the interfaces to the same VLAN to enable connection migration. Additionally, you must bind both subnet IP addresses to the same VLAN. Skip this procedure if you are using interfaces that are bound to the same VLAN.
To configure VLANs for connection migration by using the configuration utility
  1. Navigate to the System > Network > VLANs page.
  2. Select the VLAN, such as 1009, to which interface and subnet IP address of the second link is bound.
  3. Click Open.
  4. In the Interface Bindings tab of the Configure VLAN dialog box, clear the interface you are using (entry T9 of your worksheet), as shown in the following screen shot.

  5. In the IP Bindings tab, clear the entry for subnet IP address bound to the VLAN.
  6. Click OK.
  7. Open the VLAN, such as 1007, to which you want to bind the data interface.
  8. In the interface Binding tab, select the data interface (entry T9 in your worksheet)
  9. In the IP Bindings tab, select the subnet IP address (entry T5 in your worksheet) you just unbound from the other VLAN.
  10. Click OK.
To configure VLANs for connection migration by using the command line interface, run the following commands
> unbind vlan 1009 –ifnum 10/6 
> unbind vlan 1009 –IPAddress 172.17.18.2 255.255.255.0 
> bind vlan 1007 –ifnum 10/6 
> bind vlan 1007 –IPAddress 172.17.18.2 255.255.255.0
