Configuring for Network Management Applications

CDP

CDP Features

Introduction

In Switches 2650 and 6108, CDP-v1 (Cisco Discovery Protocol, version 1)

provides data that aids SNMP-based network mapping utilities designed to

discover devices running CDP in a network. To make this data available, the

switch transmits information about itself via CDP packets to adjacent devices,

and also receives and stores information about adjacent devices running CDP.

This enables each CDP device to receive and maintain identity data on each

of its CDP neighbors and pass this information off to an SNMP utility designed

to query the CDP area of the device’s MIB.

Note

To take advantage of CDP in Switches 2650 and 6108, you should have a

working knowledge of SNMP operation and an SNMP utility capable of polling

the switches for CDP data. HP’s implementation of CDP places specific data

into the switch’s Management Information Base (MIB). However, retrieval of

this data for network mapping is dependent on the operation of your SNMP

utility. Refer to the documentation provided with the utility.
