The first step to managing a network is to discover the network elements you want to manage. During discovery, PSM registers itself as a trap receiver and reads configuration and operational data from the network element. Discovered network elements are shown in the topology Map view. PSM uses SNMP (and NETCONF if applicable) to communicate with discovered network elements.
PSM supports the discovery of the following network elements:
BTI7800 Series network elements
BTI7000 Series network elements
BTI800 Series network elements
BTI700 Series network elements
MX Series and PTX Series routers
QFX Series switches
Additionally, PSM can discover any SNMP MIB-II compliant device.
