How to Discover Layer2 Connections Using Saved Files

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 Data Flow Management section of the UCMDB Help.

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 either or both of the Layer2 Topology Bridge-based by SNMP and Layer2 Topology VLAN-based by SNMP jobs, according to your environment.
4. After all the preceding jobs have completed, run the Process Layer2 Saved Files job.
