110 Confidential and Proprietary Information of ZTE CORPORATION
� Value means the actual information that need to send.
Each LLDPDU contains four forced TLVs and an optional TLV:
1. Device ID TLV
2. Port ID TLV
3. TTL TLV
4. Optional TLV
5. LLDPDU end TLV.
Device ID and port ID are used for identifying transmitter.
TTL TLV tells receiver the reserving period of all information. If the
update information from transmitter is not received in the period,
the receiver will discard all related information. IEEE has defined
a suggesting update frequency, that is, transmit one time every
30s.
Optional TLV includes basic management TLV set( such as port
description TLV), special TLV set organized IEEE 802.1, and special
TLV set organized IEEE 802.3
The occurrence of LLDPDU end TLV indicates LLDPDU is over.

Configuring LLDP

LLDP configuration includes global configuration and interface con-
figuration. Only finishes these two parts of configuration, can this
protocol take effect.
lldp enable
lldp hellotime <seconds>
lldp holdtime <multiple>
lldp {enable | rxdisable | txdisable |
LLDP Configuration
Example
Connect the two devices to implement LLDP protocol discovery, as
shown in Figure 29.
Function
This enables LLDP.
This sets LLDP packet sending
interval.
The range of lldp hellotime is
<5-32768>, the default is 30.
This sets LLDP packet aging
time, the product of hellotime
and parameter is aging time.
The range of lldp holdtime is
<2-10>, the default is 4.
This configures LLDP global or
interface management status.
