D-Link Unified Access System Software User Manual 12/10/09 LLDP-MED The Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) is an enhancement to LLDP that features: • Auto-discovery of LAN policies (such as VLAN, Layer 2 Priority and DiffServ settings), enabling plug and play networking. • Device location discovery for creation of location databases. • Extended and automated power management of Power over Ethernet endpoints. • Inventory management, enabling network administrators to track their network devices and determine their characteristics (manufacturer, software and hardware versions, serial/asset number). The LLDP-MED folder provides access to the following pages: • "LLDP-MED Global Configuration" • "LLDP-MED Interface Configuration" • "LLDP-MED Interface Summary" • "LLDP Local Device Information" • "LLDP-MED Remote Device Information" LLDP-MED Global Configuration Use this page to set global parameters for LLDP-MED operation. To display this page, click LAN > L2 Features > LLDP > LLDP-MED > Global Configuration in the navigation tree. Figure 187: LLDP Global Configuration Field Fast Start Repeat Count Device Class Table 168: LLDP Global Configuration Fields Description Specifies the number of LLDP PDUs that will be transmitted when the protocol is enabled. The range is from (1 to 10). The default value s 3. Specifies local device's MED Classification. The following three represent the actual endpoints: • Class I Generic [IP Communication Controller etc.] • Class II Media [Conference Bridge etc.] • Class III Communication [IP Telephone etc.]) The fourth device is Network Connectivity Device, which is typically a LAN switch/router, IEEE 802.1 bridge, IEEE 802.11 wireless access point, etc. • Click Submit to updated the switch. The changes take effect but will not be retained across a power cycle unless a save is performed. Page 272 Managing LLDP Document 34CSFP6XXUWS-SWUM100-D7
