When the DisableProtocolDiscovery parameter in IP Availability Manager’s tpmgr-param.conf file is set to FALSE, IP Availability Manager not only performs its traditional discovery of network objects, but it also creates BGP-, EIGRP-, IS-IS-, and OSPF-relevant topology collection sets from the discovered network objects. By default, it queries the SNMP agent of every device in the managed network for routing-protocol support.
The protocol light discovery feature is described in the IP Manager documentation.
