CHAPTER 4
WEB OPERATION & CONFIGURATION
Tx Hold:
This setting defines how long LLDP frames are considered valid and is used to compute the TTL. Valid range is
2~10 times. The default is 4.
Tx Delay:
Specify a delay between the LLDP frames that contain changed configurations. Tx Delay cannot be larger
than 1/4 of the Tx interval value. The valid values are 1 - 8192 seconds.
Tx Reinit:
Specify a delay between the shutdown frame and a new LLDP initialization. The valid values are 1
~
10
seconds.
LLDP Port Configuration
Port:
The port number. “Port *” settings apply to all ports.
Mode:
Select the appropriate LLDP mode.
Disabled:
LLDP information will not be sent and LLDP information received from neighbours will be dropped.
Enabled:
LLDP information will be sent and LLDP information received from neighbours will be analyzed.
Rx Only:
The switch will analyze LLDP information received from neighbours.
Tx Only:
The switch will send out LLDP information but will drop LLDP information received from neighbours.
CDP Aware:
CDP aware operation is used to decode incoming CDP (Cisco Discovery Protocol) frames. If enabled, CDP
TLVs that can be mapped into a corresponding field in the LLDP neighbors table are decoded, all others are discarded.
CDP TLVs are mapped into LLDP neighbors table as shown below:
Optional TLVs:
LLDP uses several attributes to discover neighbour devices. These attributes contains type, length, and
value descriptions and are referred to TLVs. Details such as port description, system name, system description, system
capabilities, management address can be sent from this device. Uncheck the boxes if they are not appropriate to be
known by other neighbour devices.
4.11.2 LLDP-MED
LLDP for Media Endpoint Devices (LLDP-MED) is an extension to LLDP that operates between endpoint devices such as
IP phones and network devices such as switches. It specifically provides support for voice over IP (VoIP) applications
and provides additional TLVs for capabilities discovery, network policy, Power over Ethernet, inventory management
and location information.
