Description
Set the LLDP operating mode on the port or ports you are configuring.
Available options include:
•
TxRx—Sends and receives LLDPDUs.
•
Tx—Sends but not receives LLDPDUs.
•
Rx—Receives but not sends LLDPDUs.
•
Disable—Neither sends nor receives LLDPDUs.
Set the encapsulation for LLDPDUs. Available options include:
•
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.
NOTE:
LLDP-CDP PDUs use only SNAP encapsulation.
Set the CDP compatibility of LLDP. Available options include:
•
Disable—Neither sends nor receives CDPDUs.
•
TxRx—Sends and receives CDPDUs
IMPORTANT:
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.
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.
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.
NOTE:
To avoid excessive traps from being sent when topology is instable, you
can tune the minimum trap transit interval on the Global Setup tab.
Select to include the port description TLV in transmitted LLDPDUs.
Select to include the system capabilities TLV in transmitted LLDPDUs.
Select to include the system description TLV in transmitted LLDPDUs.
Select to include the system name TLV in transmitted LLDPDUs.
Select 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.
