ip dhcp ping packets

To specify the number of packets a Cisco IOS Dynamic Host Configuration Protocol (DHCP) Server sends to a pool address as part of a ping operation, use the ip dhcp ping packets global configuration command. Use the no form of this command to prevent the server from pinging pool addresses.

ip dhcp ping packets count

no ip dhcp ping packets

Syntax Description

count

Indicates the number of ping packets that are sent before assigning the

 

address to a requesting client. The default value is two packets.

Defaults

Two packets

Command Modes

Global configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 12.0(1)T.

The DHCP server pings a pool address before assigning the address to a requesting client. If the ping is unanswered, the DHCP server assumes (with a high probability) that the address is not in use and assigns the address to the requesting client.

Examples

The following example specifies five ping attempts by the DHCP server before ceasing any further ping attempts:

ip dhcp ping packets 5
