Keeping a VIP Address in the Backup State

You can force a VIP address to always stay in backup state. This operation is helpful in maintenance or testing of a VRRP deployment.

When a VIP address is forced to stay in backup state, it does not participate in VRRP state transitions. Also, it cannot become master even if all other nodes go down.

To force a VIP address to stay in backup state, you set the priority of the associated VMAC address to zero. To ensure that none of the VIP addresses of a node handle traffic during a maintenance process on the node, set all the priorities to zero.

You can the set the priority of a VMAC address while adding or modifying the address.

To force a VIP address to stay in the backup state by using the NetScaler command line:

  • To set the priority while adding a VMAC, at the command prompt, type:
    • add vrID <id> -priority 0
    • show vrID
  • To set the priority while modifying a VMAC, at the command prompt, type:
    • set vrID <id> -priority 0
    • show vrID

To force a VIP address to stay in backup state by using the NetScaler GUI:

  1. Navigate to System > Network > VMAC.
  2. On the VMAC tab, while adding a new VMAC or editing an existing VMAC, set the Priority parameter to zero.
