LLDP standardizes methods for network devices to advertise themselves to other systems, and to store discovered information. LLDP enables a device to advertise its identification, configuration, and capabilities to neighboring devices that then store the data in a Management Information Base (MIB). The network management system models the topology of the network by querying these MIB databases. LLDP is a link layer protocol. By default, the switch terminates and processes all incoming LLDP packets as required by the protocol. The LLDP protocol has an extension called LLDP Media Endpoint Discovery (LLDP-MED), which provides and accepts information from media endpoint devices such as VoIP phones and video phones. For further information about LLDP-MED, see LLDP MED. LLDP Configuration Workflow Following are examples of actions that can be performed with the LLDP feature and in a suggested order. You can refer to the LLDP/CDP section for additional guidelines on LLDP configuration. LLDP configuration pages are accessible under the Administration > Discovery LLDP menu. 1. Enter LLDP global parameters, such as the time interval for sending LLDP updates using the LLDP Properties page. 2. Configure LLDP per port by using the Port Settings page On this page, interfaces can be configured to receive/transmit LLDP PDUs, specify which TLVs to advertise, and advertise the switch's management address. 3. Create LLDP MED network policies by using the LLDP MED Network Policy page. Cisco Small Business 200 Series Smart Switch Administration Guide 72
