Address Manager and DNS/DHCP Server appliances both support network redundancy through Active/Backup NIC bonding.
Network redundancy through NIC bonding is supported on Address Manager appliances and 4-port DNS/DHCP Server appliances only. It isn't supported on virtual machines.
Address Manager network redundancy:
- BlueCat recommends enabling and disabling Address Manager network redundancy from Address Manager (as opposed to the Administration Console). For details, refer to Enabling network redundancy on Address Manager.
DNS/DHCP Server network redundancy
- BlueCat recommends enabling and disabling network redundancy on DNS/DHCP Servers from the Add Server and Replace Server pages of Address Manager. However, if you will be using VLAN tagging with bonding interfaces, you can enable and disable bonding using the DNS/DHCP Administration Console. Bonding must be enabled prior to configuring VLAN interfaces.
To view the state of bonding/network redundancy on the appliance, use the Administration Console. From Main Session mode, type show interfaces and press ENTER.
- If bonding is disabled, you won't see bond0 in the list of
Proteus> show interfaces eth0: IPv4 Addresses 192.0.2.10/24 (Primary) Active = on eth1: Active = off
- If bonding is enabled, you will see details for bond0 and the bonding
Proteus> show interfaces bond0: IPv4 Addresses 192.0.2.10/24 (Primary) Active = on Bond Mode = active-backup eth0: Active = on eth1: Active = off
