How to Discover Layer2 Connections Using CDP or LLDP MIB

This task includes the following steps:

Prerequisite - Set up protocol credentials

The SNMP protocol is required to discover Layer2 objects. When defining the SNMP protocol credentials, have available the Port and Community authentication parameters.

For credential information, see Supported Protocols.
Run the discovery
For details on running jobs, refer to "Module/Job-Based Discovery" in the HPE Universal CMDB Data Flow Management Guide.

Run the jobs in the following order:
1. Run the Range IPs by ICMP job to discover the target IPs.
2. Run the Host Connection by SNMP job to discover the target host and connectivity to it.
3. Run the Layer2 Topology CDP-LLDP based by SNMP job.
