Item Description
Basic
Settings
LLDP Operating
Mode
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.
Encapsulation
Format
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.
IMPORTANT:
LLDP-CDP PDUs use only SNAP encapsulation.
CDP Operating
Mode
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.
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.
IMPORTANT:
To avoid excessive traps from being sent when topology is instable, you can tune
the minimum trap transit interval on the Global Setup tab.
Base TLV
Settings
Port Description Select to include the port description TLV in transmitted LLDPDUs.
System
Capabilities
Select to include the system capabilities TLV in transmitted LLDPDUs.
System
Description
Select to include the system description TLV in transmitted LLDPDUs.
System Name Select to include the system name TLV in transmitted LLDPDUs.
Management
Address
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.
