Similar to LLDP, Cisco Discovery Protocol (CDP) is a link layer protocol for directly
connected neighbors to advertise themselves and their capabilities to each other.
Unlike LLDP, CDP is a Cisco proprietary protocol.
This section describes how to configure CDP and includes the following topics:
•
Configuring CDP Properties
•
Configuring CDP Port Settings
•
Viewing CDP Local Information
•
Displaying CDP Neighbor Information
•
Viewing CDP Statistics
Configuring CDP Properties
Use the CDP Properties page to globally enable CDP on the switch and configure
general CDP parameters.
To define CDP properties:
Click Administration > Discovery CDP > Properties.
Enter the following information:
•
CDP Status—Check Enable to globally enable CDP on the switch.
•
CDP Frames Handling—If CDP is disabled, select the action to be taken if a
packet that matches the selected criteria is received:
-
Bridging—(VLAN-aware flooding) Forwards the packet based on the
VLAN.
-
Filtering—Deletes the packet.
-
Flooding—(VLAN-unaware flooding) Forwards incoming CDP packets to
all the ports excluding the ingress ports.
•
CDP Voice VLAN Advertisement—Check Enable to enable the switch to
advertise the voice VLAN in CDP on all ports that are CDP enabled, and are
member of the voice VLAN. The voice VLAN is configured on the Voice VLAN
> Properties page.
