6.6.1 Team Alias Note
An IP Address (North-Bound IP) alias is created on the node that is elected as team leader to allow
a controller team to be accessible with a single IP Address no matter which controller is the leader.
This IP Address is provided as part of the team configuration when creating a team. If the elected
node stops being team leader, the team IP Address must be removed from the aliases because this
address must be reassigned to the actual team leader. If assigning or removing an alias fails, one
of the following messages appears in the Alert log:
• Programming team alias < ip-address > failed
• Unprogramming team alias < ip-address > failed
In either of these instances, the condition is logged and the team continues to operate. In this case
you can manually program the team alias using the following commands:
6.6.1.1 To Set the Alias
sudo ifconfig Mask:<network_mask> eth0:0 <controller_ip>
netmask <network_mask> eth0 up
6.6.1.2 To Remove the Alias
sudo ifconfig Mask:<network_mask> eth0:0 <controller_ip> netmask
<network_mask> eth0 down
