Configuring LLDP
The Link Layer Discovery Protocol (LLDP) allows network managers to troubleshoot and enhance network
management by discovering and maintaining network topologies over multi-vendor environments. LLDP
discovers network neighbors by standardizing methods for network devices to advertise themselves to other
system, and to store discovered information. Device discovery information includes:
• Device Identification
• Device Capabilities
• Device Configuration
The advertising device transmits multiple advertisement message sets in a single LAN packet. The multiple
advertisement sets are sent in the packet
Type Length Value (TLV) field. LLDP devices must support chassis and
port ID advertisement, as well as system name, system ID, system description, and system capability
advertisements.
The
LLDP Properties page contains fields for configuring LLDP.
To open the
LLDP Properties Page, click Security → LLDP → LLDP Properties in the tree view .
Figure 1-1. LLDP Properties
Enable LLDP — Indicates if LLDP is enabled on the device. The possible field values are:
Checked — Indicates that LLDP is enabled on the device.
Unchecked — Indicates that LLDP is disabled on the device. This is the default value.

5
Updates Interval (5-32768) — Indicates that rate at which LLDP advertisement updates are sent. The
possible field range is 5 - 32768 seconds. The default value is 30 seconds.
Hold Time (2-10) — Indicates the amount of time that LLDP packets are held before the packets are dis-
carded. The possible field range is 2 - 10 seconds. The field default is 4 seconds.
Reinitializing Delay (1-10) — Indicates the amount of time that passes between disabling LLDP and when
reinitializing begins. The possible field range is 1 - 10 seconds. The field default is 2 seconds.
Transmit Delay (1-8192) — Indicates the amount of time that passes between successive LLDP frame trans-
missions due to changes in the LLDP local systems MIB. The possible field value is
1 – 8192 seconds. The field default is 2 seconds.
Configuring LLDP Using CLI Commands
The following is an example of the CLI commands:
Table 1-1. LLDP Properties CLI Commands
CLI Command Description
lldp enable (global) Enables enable Link Layer Discovery
Protocol.
lldp hold-multiplier
number Specifies the time that the receiving
device should hold a Link Layer
Discovery Protocol (LLDP) packet
before discarding it.
lldp reinit-delay
Seconds Specifies the minimum time an LLDP
port will wait before reinitializing.
lldp tx-delay
Seconds Specifies the delay between successive
LLDP frame tr.ansmissions.

State — Indicates the port type on which LLDP is enabled. The possible field values are:
Tx Only — Enables transmitting LLDP packets only.
Rx Only — Enables receiving LLDP packets only.
Tx & Rx — Enables transmitting and receiving LLDP packets. This is the default value.
Disable — Indicates that LLDP is disabled on the port.
Use Default — Indicates that information included in the TLVs is per the device defaults. The possible field
values are:
Checked — Enables sending the device default LLDP advertisements.
Unchecked — Indicates that the device LLDP advertisement settings are disabled, and LLDP
advertisement settings are user defined. This is the default value.
