LLDP Overview
LLDP is a protocol that enables network managers to troubleshoot and enhance
network management in multi-vendor environments. LLDP standardizes methods
for network devices to advertise themselves to other systems, and to store
discovered information.
LLDP enables a device to advertise its identification, configuration, and
capabilities to neighboring devices that then store the data in a Management
Information Base (MIB). The network management system models the topology of
the network by querying these MIB databases.
LLDP is a link layer protocol. By default, the switch terminates and processes all
incoming LLDP packets as required by the protocol.
The LLDP protocol has an extension called LLDP Media Endpoint Discovery
(LLDP-MED), which provides and accepts information from media endpoint
devices such as VoIP phones and video phones. For further information about
LLDP-MED, see
LLDP MED
.
LLDP Configuration Workflow
Following are examples of actions that can be performed with the LLDP feature
and in a suggested order. You can refer to the LLDP/CDP section for additional
guidelines on LLDP configuration. LLDP configuration pages are accessible under
the Administration > Discovery LLDP menu.
1. Enter LLDP global parameters, such as the time interval for sending LLDP
updates using the
LLDP Properties
page.
2. Configure LLDP per port by using the
Port Settings
page On this page,
interfaces can be configured to receive/transmit LLDP PDUs, specify which
TLVs to advertise, and advertise the switch's management address.
3. Create LLDP MED network policies by using the
LLDP MED Network Policy
page.
