        -g <poller group> allows you to add a device to be pinned to a specific poller when using distributed polling. X can be any number associated with a poller group
        -f forces the device to be added by skipping the icmp and snmp check against the host.
	-p <port assoc mode> allow you to set a port association mode for this device. By default ports are associated by \'ifIndex\'.
	                     For Linux/Unix based devices \'ifName\' or \'ifDescr\' might be useful for a stable iface mapping.
	                     The default for this installation is \'' . $config['default_port_association_mode'] . '\'
	                     Valid port assoc modes are: ' . join (', ', $valid_assoc_modes) . '
