Introduction
In Series 5300XL switches, 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 Series 5300XL switches, 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.
