Source notes citing this source

• In the Catalyst 9300 IOS XE 17.7.x guide, LLDP is globally disabled by default and is enabled with 'lldp run'. in context
• By default a Catalyst 9300 sends only plain LLDP until it receives LLDP-MED packets from the end device. Only then does it send LLDP with MED TLVs, such as network policy. in context
• Cisco's Catalyst 9300 LLDP guide says LLDP must be disabled on interfaces where CDP is used for power negotiation. in context
• On Catalyst 9300, if an LLDP-MED network-policy profile is configured on an interface first, 'switchport voice vlan' cannot be applied to that interface afterwards. If the voice VLAN is configured first, a network-policy profile can still be added. in context
