If your agent has more than one IP address it is necessary to bind the agent application to one IP address. The IP address must be reachable by the commandserver.
You can obtain the fixed IP address binding by adding a setting in the magnet.ttx configuration file on the agent.
Navigate to installation_home/bin. Edit (vi or notepad) the file magnet.ttx and add (or change already existing line to):
magnet.address="Your_fix_agent_IP_address eg. 192.168.23.14"
Save the file and restart the agent application.
WARNING: this setting shall not be done in the commandserver magnet.ttx
