Lldp - Zte ZXR10 5900E Product Description

equipment system with the appropriate service management interface for the DHCP
CLIENT. They implement transparent interaction between the DHCP CLIENT and DHCP
SERVER through the DHCP RELAY AGENT expansion option of the DHCP protocol, to
enable the dynamic address allocation and management of the DHCP CLIENT, and at
the same time provide the service management module on the destination equipment
system with the appropriate service management interface for the DHCP CLIENT.
ZXR10 5900E series support DHCP Client and automatic download of default
configuration file via DHCP option field. Without any extra configuration, the device can
get IP address, Gateway IP address, and host configuration information, etc. after
receiving discovery message, DHCP server will find corresponding preserved IP address
as per MAC address, and send other information for example host name, TFTP IP
address, Configuration file name to DHCP client via DHCP option at the same time. Then
DGCP client will download configuration file from TFTP server via this information, and
then initiate new configuration file with DHCP protocol acting to download configuration
file at the same time.

3.2.25 LLDP

LLDP（Link Layer Discovery Protocol）is a new protocol defined in 802.1ab, which
enables adjacent devices to send messages to each other, thus updates physical
topology information and establishes device management information base. LLDP
working process is as follows:
1. Sends link and management information of local device to the adjacent device;
2. Local device receives network management information from adjacent device;
3. Store the network management information of adjacent device in MIB base of local
device. Network management software can query L2 connection in MIB base.
LLDP doesn't work as configuration protocol for remote system, nor signaling control
protocol between ports. LLDP can discover inconsistency in configuration of L2 protocol
for adjacent devices, but it only reports the problem to the upper level management
device without providing mechanism to solve the problem.
