You use the dmctl invoke command to override parameter settings in the tpmgr-param.conf file. These parameters are entries for a table that is defined inside the ICF-TopologyManager object.
The syntax for the dmctl invoke command is:
dmctl -s <IP Manager instance name> invoke ICF_TopologyManager::ICF-TopologyManager insertParameter <configuration parameter name> <value>
For example:
dmctl -s INCHARGE-AM invoke ICF_TopologyManager::ICF-TopologyManager insertParameter DisableMPLSDiscovery FALSE
