ProSAFE Wireless Controller 8. Configure the VRRP ID and local IP address of all primary controllers (that is, the master and the slaves) as described in the following table. These settings are required so that the primary controllers and redundant controller can establish a redundancy group. The following table also includes descriptions of the nonconfigurable fields. Setting Controller Role Controller IP VRRP ID [1-255] Local IP Description This is a nonconfigurable field that shows that the role of the primary controller. The role is either master (for the master in the stack) or slave (for the slaves in the stack). This is a nonconfigurable field that shows the IP address of the primary controller. This IP address is the address that you use to log in to the primary controller's (master's or slave's) web management interface and was established when you configured the stack (see Configure a Stack of Wireless Controllers on page 283). Note: The controller IP address of the master in the stack is also the master IP address for the redundancy configuration. For each primary controller, enter a number from 1 through 255 as the VRRP ID. For each primary controller, this number must be unique and not assigned to any other device in the network. For each primary controller, enter a local IP address. If a failover occurs, this IP address remains assigned to the primary controller and does not transfer to the redundant controller to let you identify the primary controller before and after the failover. For each primary controller, you must enter an IP address that is not assigned to any other device. Manage Stacking and Redundancy 303
