Usage Guidelines Use this command to set parameters for VRRP on the controller. The default VRRP parameters can be left for most implementations. You can use a combination of numbers, letters, and characters to create the authentication password and the VRRP description. To include a space in the password or description, enter quotation marks around the string. For example, to create the password Floor 1, enter "Floor 1" at the prompt. To change the existing password or description, enter the command with a different string. The new password or description takes affect immediately. To unconfigure the existing password or description, enter "" at the prompt. If you update the password on one controller, you must update the password on the redundant member pair. Interface Tracking You can track multiple VRRP instances to prevent asymmetric routing and dynamically change the VRRP master to adapt to changes in the network. VRRP interface tracking can alter the priority of the VRRP instance based on the state of a particular VLAN or Layer-2 interface. The priority of the VRRP instance can increase or decrease based on the operational state of the specified interface. For example, interface transitions (up/down events) can trigger a recomputation of the VRRP priority, which can change the VRRP master depending on the resulting priority. You can track a combined maximum of 16 interfaces. You must enable preempt mode to allow a controller to take over the role of master if it detects a lower priority controller currently acting as master Example The following command configures a priority of 105 for VRRP ID (VRID) 30: (host) (config) #vrrp 30 priority 105 The following commands configure VLAN interface tracking and assumes the following: l You have two controllers, a primary and a backup. l The configuration highlights the parameters for interface tracking. You may have other parameters configured for VRRP. 2225 | vrrp Dell Networking W-Series ArubaOS 6.4.x | User Guide
