For the MultiNICB agent to function properly, you must satisfy each item in the following list:
Each interface must have a unique MAC address.
At boot time, you must configure and connect all the interfaces that are under the MultiNICB resource and give them base IP addresses.
All base IP addresses for the MultiNICB resource must belong to the same subnet as the virtual IP address.
If you specify the NetworkHosts attribute, then that host must be on the same subnet as the base IP addresses for the MultiNICB resource.
If any network host is meant to respond to a broadcast ping, run no -o bcastping=1 on the network host.
You must use the AIX SMIT configuration tool to configure the base IP addresses and to make them persistent across reboots. If you do not use SMIT to configure the IP addresses the agent may failover incorrectly.
Ensure that media speed settings are the same for both the interface and the corresponding switch port. Veritas recommends setting the media speed to full duplex mode.
