Configure the following information for DNS failover:
1. To add additional DNS server IP addresses, type the IP address into the DNS
Server field, then click Add.
2. The list box under the DNS Server field contains all DNS IP addresses for the
source and target servers. The label after the DNS IP address indicates whether
the DNS IP address belongs to the source, target, or both.
Note:
To remove an IP address from the DNS server list, select the IP address,
then click the Delete button.
3. In the Source IP column, select the checkbox next to the source IP address(es) to
be monitored for failover.
4. In the Target IP column, select the target IP address to be used when failover
occurs.
Note:
If one or more IP addresses are configured for the SMTP virtual server on
the target, the first IP address will be the default target IP address for all
source IP addresses.
If the target is monitoring multiple source IP addresses for failover, each
monitored source IP address must be mapped to a unique target IP
address.
