Control Packet Handling
Cisco Small Business 200E Series Advanced Smart Switch Command Reference
You can use the commands described in this section to control how the switch
handles packets of the Cisco Discovery Protocol (CDP), Link Layer Discovery
Protocol (LLDP), or 802. 1 X protocol.

CDP to share its own information, by default it forwards CDP packets on behalf of
connected devices within a VLAN.
