Enabling LLDP and DCBX TLV advertising
Restrictions and guidelines
To enable the device to advertise APP, ETS, and PFC data through an interface, perform the
following tasks:
•

2. Enable LLDP globally.
lldp global enable
By default:
{
If the device is started with the software default settings, LLDP is disabled globally.
{
If the device is started with the factory default settings, LLDP is enabled globally.
