Configure 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
can view this information to identify system topology and detect bad configurations on the
LAN.
The following sections describe how you can configure LLDP:
•
Configure LLDP Global Settings on page 85
• Configure LLDP Port Settings on page 87
• View the LLDP-MED Network Policy on page 88
• Configure LLDP-MED Port Settings on page 90
• View the LLDP-MED Neighbors Information on page 91
• View the Local Information Advertised Through LLDP on page 93
• View LLDP Neighbors Information on page 96
LLDP is a one-way protocol without any 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 or 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:
• Autodiscovery of LAN policies (such as VLAN, Layer 2 priority
, and Dif
fServ 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).
Configure LLDP Global Settings
You can specify the global LLDP and LLDP-MED settings that are applied to the switch.
To configure global LLDP settings:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
