4.3.3 Configuring PDP
4.3.3.1 Introduction
PDP is a two-layer protocol specially used to detect network devices. PDP is used in Network Management
Service (NMS) to detect all neighboring devices of a already known device. Using PDP enable you to learn
the SNMP angent address and the types of neighboring devices. After neighboring devices are detected
through PDP, the NMS can require neighboring devices through SNMP to obtain the network topology.
Our switches can detect neighboring devices through PDP, but cannot require neighboring devices through
SNMP. Therefore, these switches have to be located at the verge of networks. Otherwise, the complete
network topology cannot be obtained.
PDP on switches can be configured on all SANPs, such as Ethernet.
4.3.3.2 PDP configuration tasks
 Default PDP configuration of the switch
 Setting the PDP clock and information saving time
 Setting the PDP version
 Enabling the PDP on the switch
 Enabling the PDP on the port of the switch
 Monitoring and managing PDP
a) Default PDP configuration of the switch
Function Default Setting
PDP global configuration state Disabled
PDP port configuration state Disabled
PDP clock (frequency for sending messages) 60 seconds
PDP information saving 180 seconds
PDP version 2
b) Setting the PDP clock and information saving time
Run the following commands in global configuration mode to set the frequency for PDP to send
messages and the PDP information saving time:
Command Purpose
pdp timer seconds
Sets the frequency for PDP to send messages.
pdp holdtimeseconds
Sets the PDP information saving time.
c) Setting the PDP version
Run the following command in global configuration mode to set the PDP version:
Command Purpose
pdp version {1|2}
Sets the PDP version.
