The following table lists the configuration DNS/DHCP Server services and indicates
whether the service can be configured on DNS/DHCP Servers operating in an xHA
pair:
| DNS/DHCP Server service | Supported on xHA | Additional information |
|---|---|---|
| Additional IP addresses | Yes* | *Configuration of network routes is not supported for DNS/DHCP Servers operating in an xHA pair. |
| Anycast | No | |
| BlueCat Gateway | No | |
| DNS Activity | Yes | |
| DNS Edge Service Point | No | |
| DNS name servers | Yes | |
| DNS/DHCP Server firewall | Partially | The Allow Ping option is not supported for DNS/DHCP Servers operating in an xHA pair.* |
| NTP | Yes | |
| SNMP | Yes | |
| SSH | No | |
| Syslog redirection | Yes |
*Applying this option to an xHA pair will only affect the current active server. Configure Allow Ping settings on DNS/DHCP servers individually before pairing. To work with an existing xHA pair, users can configure Allow Ping on the active, perform a failover, then configure it again on the new active.
