Command Reference Guide
ip dhcp ping packets <number>
Use the ip dhcp ping packets command to specify the number of ping packets the Dynamic Host
Configuration Protocol version 4 (DHCPv4) server will transmit 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 prevent the
DHCPv4 server from using ping packets as part of the IPv4 address assignment process.
Syntax Description
<number>
Default Values
By default, the number of DHCPv4 server ping packets is set at 2 packets.

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. Configuring the ip dhcp ping packets command with a
value of 0 prevents the DHCPv4 server from using ping packets as part of the IPv4 address assignment
process.
Usage Examples
The following example configures the DHCPv4 server to transmit 4 ping packets before assigning an
address:
(config)#ip dhcp ping packets 4
60000CRG0-35E
Specifies the number of DHCPv4 ping packets sent on the network before
assigning the IPv4 address to a requesting DHCPv4 client.
