Configuring LLDP Properties
Use the LLDP Properties page to enable LLDP globally and configure general
LLDP parameters.
To define LLDP properties:
Click Administration > Discovery LLDP > Properties.
Enter the following information:
•
LLDP Status—Check Enable to enable LLDP on the switch (enabled by
default).
•
LLDP Frames Handling—If LLDP is disabled, select the action to be taken if
a packet that matches the selected criteria is received:
-
Filtering—Deletes the packet.
-
Bridging—(VLAN-aware flooding) Forwards the packet to all VLAN
members.
-
Flooding—Forwards the packet to all ports.
•
TLV Advertise Interval—Select User Defined to enter the rate in seconds
at which LLDP advertisement updates are sent, or select Use Default to use
the default value (30 seconds).
•
Hold Multiplier—Select User Defined to set the amount of time that LLDP
packets are held before the packets are discarded, measured in multiples of
the TLV Advertise Interval. For example, if the TLV Advertise Interval is 30
seconds, and the Hold Multiplier is 4, then the LLDP packets are discarded
after 120 seconds. You can select Use Default to use the default value (4).
•
Reinitializing Delay—Select User Defined to enter the time interval in
seconds that passes between disabling and reinitializing LLDP, following an
LLDP enable or disable cycle, or select Use Default to use the default value
(2 seconds).
•
Transmit Delay—Select User Defined to enter the amount of time in
seconds that passes between successive LLDP frame transmissions due to
changes in the LLDP local systems MIB, or select Use Default to use the
default value (2 seconds).
In the Fast Start Repeat Count field, enter the number of times that LLDP packets
are sent when the LLDP MED Fast Start mechanism is initialized. This occurs when
a new endpoint device links to the switch. Refer the
Network Policy
section for more details.
