Background

When a NetScaler instance is provisioned on a SDX appliance, XenServer internally assigns a MAC address to a virtual interface associated with that instance. The same MAC address might be assigned to a virtual interface associated with another instance on the same appliance or on another appliance. To avoid duplicate MAC addresses, unique MAC addresses can be assigned.

Instructions

A MAC address can be assigned to a NetScaler instance by completing one of the following procedures:

Generated: Assign MAC Address at Global Level

To assign MAC address at global level, complete the following steps:

1. Go to SVM > Configuration > Interface > System > Interfaces.

2. Select the corresponding Interface and click Modify.

   

   In the preceding example, the Interface 1/6 of MAC address 02:33:33:33:33:33 is changed to 02:33:33:33:33:3B.
   The SVM reflects the base MAC address as shown in the following screen shot:

   

   Note: A maximum of 8 MAC addresses can be assigned to 1 Gigabit port and a maximum of 64 MAC addresses to 10 Gigabit port.
   Now, modify the instance to reflect the new MAC address.

3. Go to SVM > Configuration > NetScaler > Instance.

4. Select the corresponding instance, right-click and choose Modify.

5. Follow till you reach Network Settings and choose the interface with MAC Address Mode as Generated.

   

6. Follow the prompt to restart.

Custom: Assign MAC Address at Instance Level

If the administrator needs to assign a customized MAC for only one Instance, complete the following steps:

1. Go to SVM > Configuration > NetScaler > Instance.

2. Select the corresponding instance, right-click and choose Modify.

3. Follow till you reach Network Settings and then specify the customized address in MAC address field as shown in the following screen shot:

   

   After following the prompt to restart, the instance reflects the customized MAC address as shown in the following screen shot:

   

The base MAC address that is assigned either at global or instance level must have the left most byte and the right most bit in that byte has to be 0 and the second most bit from the right has to be 1 (for example, 0000 0010). If not, the following error message is displayed in Modify Interface:
