Link Discovery Prerequisites

Although Dell OpenManage Network Manager automates link discovery, you must enable the

sources for link discovery information on the devices where you do such discovery.

Data sources used to derive links appear listed below. These sources are typically required for the

network operations, so if all the sources are disabled, there would be no network to manage in the

first place. The more of the sources are enabled, the higher is the quality of links discovered.

Data sources supported:

• IEEE Link Layer Discovery Protocol (LLDP) support

• Cisco Discovery Protocol (CDP) support (reserved for future use)

• Extreme Discovery Protocol (EDP) support (reserved for future use)

•VLAN support

• Spanning Tree Protocol (IEEE STP/RSTP/PVSTP+/PVSTP+) support

• AFT support
