ProSafe M5300 Switch LLDP The IEEE 802.1AB-defined standard, Link Layer Discovery Protocol (LLDP), allows stations on an 802 LAN to advertise major capabilities and physical descriptions. This information is viewed by a network manager to identify system topology and detect bad configurations on the LAN. From the LLDP link, you can access the following pages: • LLDP on page 93 • LLDP-MED on page 100 LLDP is a one-way protocol; there are no request/response sequences. Information is advertised by stations implementing the transmit function, and is received and processed by stations implementing the receive function. The transmit and receive functions can be enabled/disabled separately per port. By default, both transmit and receive are disabled on all ports. The application is responsible for starting each transmit and receive state machine appropriately, based on the configured status and operational state of the port. The Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) is an enhancement to LLDP with the following 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). LLDP From the LLDP link, you can access the following pages: • LLDP Global Configuration on page 94 • LLDP Interface Configuration on page 95 • LLDP Statistics on page 96 • LLDP Local Device Information on page 97 • LLDP Remote Device Information on page 99 • LLDP Remote Device Inventory on page 100 Configuring System Information 93
