Advanced Options Archive Data- Checking this archives current data before collecting information about and discovering links. Ignore / Include Links with Incomplete Endpoint Information-Select the option best suited for your network. Click Add Schedule to schedule link discovery, or Execute to run it now (and confirm you are willing to wait for results in a subsequent screen). The Job Viewer tab in the link discovery screen displays the message traffic between Dell OpenManage Network Manager and the device(s). See Audit Trail Portlet on page 93 for more about Job Viewer screens. 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 Managed Resources | Resource Management 177
