This guide describes the Link Layer Discovery Protocol (LLDP), LLDP for Media Endpoint Devices (LLDP-MED) and Voice VLAN, and general configuration information for these. LLDP is a Layer 2 protocol defined by the IEEE Standard 802.1AB-2005. Your switch supports LLDP as specified in this standard, including Annex F and Annex G. LLDP allows network devices to share device-related information to or from directly connected devices on the network. LLDP is designed to be managed with the Simple Network Management Protocol (SNMP), and SNMP-based Network Management Systems (NMS). LLDP can be configured, and the information it provides can be accessed, using either the command line interface or SNMP.
