ip dhcp-server ping packets <#packets>

Use the ip dhcp-server ping packets command to specify the number of ping packets the DHCP server
will transmit before assigning an IP address to a requesting DHCP client. Transmitting ping packets
verifies that no other hosts on the network are currently configured with the specified IP address. Use the
no form of this command to prevent the DHCP server from using ping packets as part of the IP address
assignment process.
Syntax Description

the IP address to a requesting DHCP client

Command History
Release 2.1 Command was introduced.
Functional Notes
Before assigning an IP address to a requesting client, the AOS
DHCP server transmits a ping packet on
the network to verify there are no othe r netwo rk hosts already configured with the specified address. If the
DHCP server receives no re ply, the IP address is assigned to the re questing client and added to the DHCP
database as an assign ed address. Configuring the ip dhcp-server p ing p acket s command with a value of
0 prevents the DHCP serve r fro m usin g pin g packets as part of the IP address ass ign m en t pro ce ss .
Usage Examples
The following example configures the DHCP server to transmit four ping packets before assigning an
address:
(config)#ip dhcp-server ping packets 4
