Use the cdp pdu Global Configuration mode command when CDP is not enabled
globally. It specifies CDP packets handling when CDP is globally disabled. The no
format of this command returns to default.
Syntax
cdp pdu [filtering | bridging | flooding]
no cdp pdu
Parameters
•
filtering—Specify that when CDP is globally disabled, CDP packets are
filtered (deleted).
•
bridging—Specify that when CDP is globally disabled, CDP packets are
bridged as regular data packets (forwarded based on VLAN).
•
flooding—Specify that when CDP is globally disabled, CDP packets are
flooded to all the ports in the product that are in STP forwarding state,
ignoring the VLAN filtering rules.
Default Configuration
bridging
Command Mode
Global Configuration mode
User Guidelines
When CDP is globally enabled, CDP packets are filtered (discarded) on
CDP-disabled ports.
In the flooding mode, VLAN filtering rules are not applied, but STP rules are
applied. In case of MSTP, the CDP packets are classified to instance 0.
