Link Layer Discovery Protocol (LLDP)

MACaddr

By default LLDP is disabled on all Cisco devices. To use LLDP on a Cisco device, you need to globally enable LLDP and allow the interface to transmit/receive LLDP packets.
From <https://www.grandmetric.com/knowledge-base/design_and_configure/lldp-configuration-example-cisco/>

To GLOBALLY enable & disable LLDP:
	Switch# configure terminal
	Switch(config)# lldp run
	Or
	Switch(config)# no lldp run

To activate LLDP to transmit/receive on the INTERFACE:
	Switch# configure terminal
	Switch(config)# interface GigabitEthernet 1/1
	Switch(config-if)# lldp transmit
	Switch(config-if)# lldp receive
	Switch(config-if)# end

To transmit LLDP packets only:
	Switch# configure terminal
	Switch(config)# no lldp receive

To configure LLDP frequency reorting:
	Switch# configure terminal
	Switch(config)# lldp holdtime 120
	Switch(config)# lldp reinit 2
Switch(config)# lldp timer 30
To Verify/clear syntax: 
	switch# show lldp
	switch# show lldp traffic
	switch# show lldp entry entry
	switch# show lldp interface interface-id
	switch# show lldp neighbors interface-id
	switch# show lldp errors
	switch(config-if)# show lldp interface <ethernet G1//1/>
	switch# clear lldp counters
	switch# clear lldp table
