Item Description

Basic
Settings

LLDP Operating Mode

Set the LLDP operating mode on the port or ports you are configuring:

TxRx—Sends and receives LLDPDUs.

Tx—Sends but does not receive LLDPDUs.

Rx—Receives but not does not send LLDPDUs.

Disable—Neither sends nor receives LLDPDUs.

Encapsulation Format

Set the encapsulation for LLDPDUs:

ETHII—Encapsulates outgoing LLDPDUs in Ethernet II frames and

processes an incoming LLDPDU only if its encapsulation is Ethernet II.

SNAP—Encapsulates outgoing LLDPDUs in Ethernet II frames and

processes an incoming LLDPDU only if its encapsulation is Ethernet II.

LLDP-CDP PDUs use only SNAP encapsulation.

CDP Operating Mode

Set the CDP compatibility of LLDP:

Disable—Neither sends nor receives CDPDUs.

TxRx—Sends and receives CDPDUs

To enable LLDP to be compatible with CDP on the port, you must enable
CDP compatibility on the Global Setup tab and set the CDP operating
mode on the port to TxRx.

LLDP Polling Interval

Enable LLDP polling and set the polling interval.
If no polling interval is set, LLDP polling is disabled.
With the polling mechanism, LLDP periodically detects local

configuration changes. If a configuration change is detected, an LLDPDU
is sent to inform the LLDP neighbors of the change.

LLDP Trapping

Set the enable status of the LLDP trapping function on the port or ports.
LLDP trapping is used to report to the network management station critical
events such as new neighbor devices detected and link failures.
To avoid excessive traps from being sent when topology is instable, tune
the minimum trap transit interval on the Global Setup tab.

LLDPDUs.

System Description

Select the box to include the system description TLV in transmitted
LLDPDUs.

System Name

Select the box to include the system name TLV in transmitted LLDPDUs.

Management Address

Select the box to include the management address TLV in transmitted
LLDPDUs and, in addition, set the management address and its format (a

numeric or character string in the TLV).
If no management address is specified, the main IP address of the lowest

VLAN carried on the port is used. If no main IP address is assigned to the
VLAN, 127.0.0.1 is used.
