CDP Features
Introduction
In a Switch 4108GL, 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. 
N o t e
To take advantage of CDP in Switch 4108GL, 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.
