The standard sets information fields that must be included in a mandatory way. Other fields
are optional and the user can select the information of each of them.
Accessing information through SNMP necessarily implies that the SNMP agent is
enabled.
The device controls the execution of the LLDP protocol through a CheckBox parameter,
and offer additional, specific parameters for each of the ports, which are the following:
• Admin Status. It sets the operation mode of the LLDP agent of the interface. Valid
values are TxRx, TxOnly, RxOnly and disabled. The default value is TxRx.
• Tx Interval. It sets the time between the transmission of messages, in normal
operation. The units are seconds, and 30 is the default value and recommended.
Valid values are 1 to 3600.
• Hold. The value of this parameter is used as a multiplier on Tx Interval and
determines the value of txTTL that is included in the LLDP messages sent by the
agent. 4 is the default value and recommended. Valid values are 1 to 100.
• Reinit. It sets the period of time between the setting of Admin Status as disabled and
the reinitialization attempt. The units are seconds, and 2 is the default value and
recommended. Valid values are 1 to 10.
• Credit Max. It sets the maximum number of consecutive LLDP messages that can
be transmitted at any time. 5 is the default value and recommended. Valid values are
1 to 10.
• Tx Interval Fast. It sets the period of sending LLDP messages in the period of high-
speed transmission, which is activated automatically when a neighbouring device is
detected. 1 is the default value and recommended. Valid values are 1 to 3600.
• Mess num Fast. It sets the number of LLDP messages that will be sent during a
high-speed transmission. 4 is the default value and recommended. Valid values are 1
to 8.
• Tx Notif. Enable. Indicates to the LLDP agent whether SNMP (traps) notifications
must be sent when changes occur in the remote information received in the interface.
In order for SNMP notifications to be effectively sent, they must be explicitly
allowed to be sent in the SNMP menu.
