Cisco Small Business SG200 Series 8-port Smart Switches Administration Guide
You can use the Control Packet Forwarding page to configure how the switch
handles packets of the following protocol types:
•
CDP-The Cisco Discovery Protocol (CDP), which is supported on many
types of Cisco networking equipment. CDP enables directly connected
devices to share information such as their IP addresses, capabilities, and
software versions. Although the switch does not itself support CDP, by
default it forwards CDP packets on behalf of connected devices within a
VLAN.
•
Dot1X-The IEEE 802. 1 X protocol defines how Extensible Authentication
Protocol (EAP) packets are encapsulated over a LAN. Dot1X provides a way
to authenticate users and allow or deny them access to services made
available by switch ports. See 802. 1 X for information on configuring the
Dot1X feature on the switch.
•
LLDP-Network devices use the Link Layer Discovery Protocol to advertise
their capabilities to other devices. See LLDP-MED for information on
configuring the LLDP feature on the switch.
To configure control packet forwarding:
Click Administration > Control Packet Forwarding in the navigation window.
Select the protocol you want to configure (CDP, LLDP, or DOT1x).
Select the action that a port will take when received packets of the specified type:
•
Drop—All packets of the selected type are dropped.
•
Forward—All packets of the selected type are forwarded within the
specified VLAN.
•
Terminate—The packet is accepted and processed on the switch. This
option is not available for CDP packets.
Click Apply. Your changes are saved to the Running Configuration.
