Item Description
CDP Operating Mode
Set the CDP compatibility of LLDP. Available options
include:
z
Disable: Neither sends nor receives CDPDUs.
z
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, you can tune the minimum trap transit interval on
the Global Setup tab.
