You can use the interfaces configuration to configure IP addresses for
interfaces, including bonding interfaces and static routes.
Configuring interface IP addresses
Example
#cloud-config
bluecat_service_config:
payload: |
{
"version": "1.3.0",
"services": {
"interfaces": {
"configurations": [
{
"interfacesConfiguration": {
"networkInterfaces": [
{
"eth0": {
"physical": {
"active": true,
"description": "eth0cloudinit",
"v4addresses": [
{
"ip4": "172.12.0.174",
"cidr": 16
}
],
"v6addresses": []
}
}
}
],
"routes": [],
"dedicatedManagement": false
}
}
]
}
}
}Parameters
networkInterfaces—enter the network interfaces that you would like to configure. You can configure ethernet interfaces (eth) or bonding interfaces (bond).For more information on configuring bonding interfaces, refer to Configuring bonding interfaces.
active—set to true to activate the specified interface; set to false to deactivate the specified interface.description—enter a description for the specified interface. You can enter up to 80 alphanumeric characters including spaces, but excluding special characters.v4addresses—enter the IPv4 addresses that you would like to configure for the interface.ip4—enter the IPv4 address of the specified interface.cidr—enter the CIDR of the IP space for the specified interface.
v6addresses—enter the IPv6 addresses that you would like to configure for the interface.ip6—enter the IPv6 address of the specified interface.cidr—enter the CIDR of the IP space for the specified interface.
routes—enter the static route information.For more information on static route configuration, refer to Configuring static routes.
dedicatedManagement—set to false. Dedicated management is only supported for DNS/DHCP Servers.
Configuring bonding interfaces
You can configure network redundancy through port bonding.
Supported bonding modes
Address Manager supports network redundancy through Active/Backup NIC bonding on Address Manager appliances.
The Active/Backup bonding mode provides fault tolerance when the primary
interface (eth0) fails. If the primary interface fails due to physical hardware failure or
network outage, the secondary interface (eth1) will take over transparently.
Note:
- Address Manager network redundancy is supported on Address Manager appliances only. For customers running Address Manager virtual machines, BlueCat recommends using the virtual server’s infrastructure redundancy mechanism for physical interfaces.
- Address Manager network redundancy requires that the eth0 and eth1 interfaces be physically connected to the same subnet.
- Network redundancy through Active/Active NIC bonding is not supported on Address Manager appliances.
Note: Enabling/disabling
redundancy may require re-wiring of your network switch. BlueCat strongly recommends scheduling a
maintenance window during non-peak times for any changes to
network redundancy/port bonding. For more information on Address Manager network redundancy, refer to Network redundancy.

bond—enter the network interfaces that you would like to configure.mode—enter a value ofactiveBackupto indicate Active/Backup NIC bonding.active—set to true to activate the specified interface; set to false to deactivate the specified interface.description—enter a description for the specified interface. You can enter up to 80 alphanumeric characters including spaces, but excluding special characters.v4addresses—enter the IPv4 addresses that you would like to configure for the interface.ip4—enter the IPv4 address of the specified interface.cidr—enter the CIDR of the IP space for the specified interface.
v6addresses—enter the IPv6 addresses that you would like to configure for the interface.ip6—enter the IPv6 address of the specified interface.cidr—enter the CIDR of the IP space for the specified interface.
routes—enter the static route information.For more information on static route configuration, refer to Configuring static routes.
dedicatedManagement—set to false. Dedicated management is only supported for DNS/DHCP Servers.
Configuring static routes
Add static routes in to indicate where the system should send packets intended for certain IP addresses.
Packets to be sent to hosts on the same subnet as the Address Manager server can be routed directly to that subnet. The same procedures can be used to manage either IPv4 or IPv6 routes.
Note: IPv4 and IPv6 static routes are persisted by Address Manager servers after a reboot or
after performing a software upgrade.
