Enabling LLDP globally
The protocol lldp command enables LLDP globally on all interfaces unless it has been specifically
disabled on an interface, or the global LLDP disable command has been executed. LLDP is globally
enabled by default.
To enable LLDP globally, perform the following steps from privileged EXEC mode.
1. Enter the configure terminal command to change to global configuration mode.
switch# configure terminal
2. Enter LLDP configuration mode.
switch(config)# protocol lldp
3. Enter the copy running-config startup-config command to save your configuration changes.
Disabling LLDP globally
LLDP is enabled globally by default. These instructions allow you to disable LLDP globally without
changing any other aspect of the LLDP configuration.
NOTE
The disable command executed in LLDP protocol configuration mode disables LLDP globally. To re-
enable LLDP, refer to
Enabling LLDP globally on page 453.
To disable LLDP globally, perform the following steps from global configuration mode.
