Configuring HA<br />

Cluster ID—Select an ID that will be assigned to the HA cluster.<br />

This allows you to distinguish between and manage multiple HA<br />

clusters, if needed. Each <strong>Sidewinder</strong> <strong>G2</strong> with an HA cluster must be<br />

assigned the same cluster ID. Valid values are 1–255.<br />

Multicast Address—This field displays the address <strong>of</strong> the multicast<br />

group used for HA purposes in the heartbeat burb. The default<br />

address is 239.192.0.1. To modify the address, click Edit Address.<br />

When you have finished configuring this window, click Next.<br />

12. [Conditional] The High Availability Advanced Network Properties<br />

window allows you to configure interface testing and force ARP reset<br />

properties. To configure interface testing and/or ARP reset properties,<br />

do the following and then click Next.<br />

Note: For more information on interface testing with HA, see “Interface<br />

configuration issues with HA” on page F-34.<br />

Note: This window does not appear if you selected the Use default advanced High<br />

Availability properties and skip advanced screens check box in the High<br />

Availability Cluster Common Addresses window.<br />

a. In the Interface Test area, configure any remote test IP addresses for<br />

networks that you want to periodically ping, as follows:<br />

Highlight the network row that you want to modify, and click<br />

Modify. The Remote Test window appears.<br />

In the Remote Test IP field, enter the IP address that the<br />

<strong>Sidewinder</strong> <strong>G2</strong> will periodically ping. The remote address must be<br />

a highly reliable system that is directly attached to the <strong>Sidewinder</strong><br />

<strong>G2</strong> network. For example, if you use a VRRP (Virtual Router<br />

Redundancy Protocol) cluster, you can specify the VRRP address <strong>of</strong><br />

the router as your remote ping address. (However, some VRRP<br />

routing clusters will only respond to pings if the configured<br />

primary router is currently acting as the primary. If you are using<br />

this type <strong>of</strong> VRRP routing cluster, you should use an alternative<br />

remote address.)<br />

For load sharing HA, if remote ping fails on one <strong>of</strong> the two cluster<br />

members, that member will become unavailable until the remote<br />

interface is again detected. If there is only one active cluster<br />

member and a remote ping failure is detected, that member will<br />

audit the failure and remain in the cluster until another member<br />

joins the cluster (without a ping failure), or until the remote<br />

system is detected.<br />

Note: If you specify 255.255.255.255 in this field, HA will only test the status <strong>of</strong> the<br />

interface rather than send data to verify that the interface is up.<br />
