GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches 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. A network manager views this information to identify system topology and detect bad configurations on the LAN. From the LLDP menu, you can access the features described in the following sections: • LLDP Configuration • LLDP Port Settings • LLDP-MED Network Policy • LLDP-MED Port Settings • Local Information • Neighbors Information LLDP is a one-way protocol; there are no request-response sequences. Stations advertise information by implementing the transmit function, and stations implementing the receive function receive and process information. The transmit and receive functions can be enabled or disabled separately per port. By default, both the transmit and receive functions are enabled 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: • Autodiscovery 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 number and asset number). LLDP Configuration Use the LLDP Configuration screen to specify LLDP and LLDP-MED parameters that are applied to the switch. To configure global LLDP settings: 1. Select System > LLDP > Basic > LLDP Configuration. Configuring System Information 56
