7.8.1 Team alias node

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-addressfailed

•Unprogramming team alias ip-addressfailed

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:

7.8.1.1 Configuring the alias

sudo ifconfig Mask:network_masketh0:0 controller_ip netmask network_mask

eth0 up

7.8.1.2 Disabling the alias

sudo ifconfig Mask:network_mask eth0:0 controller_ipnetmask network_masketh0 down
