Description
Click the radio buttons to enable or disable the LLDP feature.
When LLDP is disabled this function controls the LLDP packet forwarding message based
on individual ports. If LLDP is enabled on a port it will flood the LLDP packet to all ports
that have the same port VLAN and will advertise to other stations attached to the same
IEEE 802 LAN.
This interval controls how often active ports retransmit advertisements to their neighbors.
To change the packet transmission interval, enter a value in seconds (5 to 32768).
This function calculates the Time-to-Live for creating and transmitting the LLDP
advertisements to LLDP neighbors by changing the multiplier used by an LLDP Switch.
When the Time-to-Live for an advertisement expires the advertised data is then deleted
from the neighbor Switch's MIB.
The LLDP re-initialization delay interval is the minimum time that an LLDP port will wait
before reinitializing after receiving an LLDP disable command. To change the LLDP re-init
delay, enter a value in seconds (1 to 10).
LLDP TX Delay allows the user to change the minimum time delay 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
8192).
LLDP Notification Interval is used to send notifications to configured SNMP trap
receiver(s) when an LLDP change is detected in an advertisement received on the port
from an LLDP neighbor. To set the LLDP Notification Interval, enter a value in seconds (5
to 3600).
