send out LLDP information.
Disabled The switch will not send out LLDP information, and will drop LLDP
information received from neighbors.

Only CDP TLVs that can be mapped to a corresponding field in the
neighbours' table are decoded. All other TLVs are discarded (Unrecognized CDP
TLVs and discarded CDP frames are not shown in the LLDP statistics.).

shown in the LLDP neighbours table.

Both the CDP and LLDP support "system capabilities", but the
cover capabilities that are not part of the LLDP. These capabilities are shown as
"others" in the LLDP neighbours' table.
If all ports have CDP awareness disabled the switch forwards
