Enabling LLDP Polling
With LLDP polling enabled, a device checks for local configuration changes periodically. Upon detecting
a configuration change, the device sends LLDP frames to inform the neighboring devices of the change.
Follow these steps to enable LLDP polling:

By default, all types of
LLDP TLVs except

Configuring the Management Address
The management address of a device is used by the network management system to identify and
manage the device for topology maintenance and network management. The management address is
encapsulated in the management address TLV. LLDP encodes management addresses in numeric
format in management address TLVs.
Make sure that a neighbor also encodes its management address in numeric format to guarantee
normal communication with the neighbor.
Follow these steps to configure a management address to be advertised on a port:
