The Discovery IP Failover Screen is used to specify whether or not OmniVista will use a device's alternate IP address for SNMP traffic if the primary IP address fails. If IP Failover is enabled and a device fails to respond to SNMP requests, the OmniVista Server tries to reach the switch using the alternate IP address. If the attempt is successful, all subsequent management traffic is diverted to this new address. Use the IP Failover slider to enable (On) or disable (Off) the feature and click on the Apply button.
