DNS/DHCP Server employs a Primary Service IP address to support VLAN tagging, multiple service IP addresses, and bonding interfaces. The Primary Service IP is the principal address for DNS service regardless of the number of IP addresses configured on the Services Interface (by default, eth0).
Running the set address command from the Administration Console automatically configures the Primary Service IPv4 address, respectively. However, customers configuring VLAN interfaces or bonding interfaces (or both) can run the set primary command from the DNS/DHCP Server Administration Console to change the Primary Service IP address manually.
- The Primary Service IP can only be configured on DNS/DHCP Server appliances and VMs.
- There can be only one primary IPv4 address on a managed DNS/DHCP Server.
The Primary Service IP address cannot be removed. However, it can be configured on a different Service interface (for example, if the Primary IP is currently set on eth0 and you want to set it on VLAN eth0.100). BlueCat advises extreme caution if attempting to change the Primary Service IP address. Changing the Primary Service IP address may result in a restart of all running services associated with that Services interface (such as services running on additional IP addresses, loopback addresses, and VLAN interfaces) and/or loss of connectivity with Address Manager.
BlueCat advises extreme caution if attempting to change the Services interface associated with the Primary IP address (for example, if the Service interface and Primary IP are configured on eth0, but you want to configure the Service interface on VLAN eth0.100). Changing the Services Interface may result in a restart of all running services. That is, changing the Services interface may result in a restart of services running on additional IP addresses, loopback addresses, and VLAN interfaces.
To set the Primary Service IP address:
- From Main Session mode, type configure interfaces and press ENTER.
- Type modify <interface> and press ENTER.
- Type set primary <ipv4address> and press ENTER.
- Type save and press ENTER. The Administration Console saves your settings.
- Type exit and press ENTER until you return to Main Session mode.
