This window is used to configure the LLDP Global Settings on the Switch. When LLDP is enabled the Switch can start
to transmit, receive and process LLDP packets. The specific function of each port will depend on the per port LLDP
settings. LLDP Global State is Disabled by default.
To view this window, click L2 Features > LLDP > LLDP Global Settings as shown below:
Figure 3 - 66 LLDP Global Settings window
The following parameters can be set:
Parameter Description
LLDP State Used to Enable or Disable LLDP on the Switch.
LLDP Forward
Message When LLDP is disabled, this function controls the LLDP packet for warding. It will flood the
received LLDP packet to all ports that have the same VLAN and will advertise to other stations
attached to the same IEEE 802 LAN. When LLDP is enabled, this function d oes not take effect.
Message TX
Interval (5-32768) This interval controls how often active ports retransmit advertisements to their neighbors. T o
change the packet transmission interval, enter a value in seconds (5 t o 32768).
Message TX Hold
Multiplier (2-10) This function calculates the Time-to-Live for creating and transmitting the LLDP advertisem ents
to LLDP neighbors by changing the multiplier used by an LLDP Switch. W hen the Time-to-Live
for an advertisement expires the advertised data is then deleted from the neighbor Switch’s MIB.
LLDP Reinit
Delay (1-10) The LLDP reinitialization delay interval is the minimum time that an LLDP port will wait before
reinitializing after receiving an LLDP disable command. To change the LLD P Reinit Dela y, enter
a value in seconds (1 to 10).
LLDP TX Delay
(1-8192) LLDP TX Delay allows the user to change the minimum time dela y interval for any LLDP port
which will delay advertising any successive LLDP advertisements due to change in the LLDP
MIB content. To change the LLDP TX Delay, enter a value in seconds (1 to 819 2).
LLDP Notification
Interval (5-3600) LLDP Notification Interval is used to send notifications to configured SN MP tr ap r ecei ver( s ) when
an LLDP change is detected in an advertisement received on t he port from an LLDP neighbor.
To set the LLDP Notification Interval, enter a value in seconds (5 to 3600).
