Command Reference Guide
ip dhcp ping timeout <value>
Use the ip dhcp ping timeout command to specify the interval (in milliseconds) the Dynamic Host
Configuration Protocol version 4 (DHCPv4) server will wait for a response to a transmitted DHCPv4 ping
packet. The DHCPv4 server transmits ping packets before assigning an IPv4 address to a requesting
DHCPv4 client. Transmitting ping packets verifies that no other hosts on the network are currently
configured with the specified IPv4 address. Use the no form of this command to return to the default
timeout interval.
Syntax Description

Default Values
By default, the ip dhcp ping timeout is set to 500 milliseconds.

Functional Notes
Before assigning an IPv4 address to a requesting client, the AOS DHCPv4 server transmits a ping packet
on the network to verify there are no other network hosts already configured with the specified address. If
the DHCPv4 server receives no reply, the IPv4 address is assigned to the requesting client and added to
the DHCPv4 database as an assigned address.
Usage Examples
The following example configures the DHCPv4 server to wait 900 milliseconds for a response to a
transmitted DHCPv4 ping packet before considering the ping a failure:
(config)#ip dhcp ping timeout 900
60000CRG0-35E
Specifies the number of milliseconds the DHCPv4 server will wait for a
response to a transmitted DHCPv4 ping packet. Valid range is 1 to
1000 milliseconds.
