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.
Base TLV
Settings
Port Description Select the box to include the port description TLV in transmitted LLDPDUs.
System Capabilities
Select the box to include the system capabilities TLV in transmitted
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.
DOT1 TLV
Setting
Port VLAN ID Select the box to include the PVID TLV in transmitted LLDPDUs.
Protocol VLAN ID
Select the box to include port and protocol VLAN ID TLVs in transmitted
LLDPDUs and specify the VLAN IDs to be advertised.
If no VLAN is specified, the lowest protocol VLAN ID is transmitted.
VLAN Name
Select the box to include VLAN name TLVs in transmitted LLDPDUs, and
specify the VLAN IDs to be advertised.
If no VLAN is specified, the lowest VLAN carried on the port is
advertised.
DOT3 TLV
Setting
Link Aggregation
Select the box to include the link aggregation TLV in transmitted
LLDPDUs.
