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
<#packets> Specifies the number of DHCP ping packets sent on the network before assigning
the IP address to a requesting DHCP client
Default Values
By default, the number of DHCP server ping packets is set at 2 packets.
Applicable Platforms
This command applies to the NetVanta 300, 1000, 1000R, 2000, 3000, 4000, and 5000 and
Total Access 900 Series units.
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 other network hosts already configured with the specified address. If the
DHCP server receives no reply, the IP address is assigned to the requesting client and added to the DHCP
database as an assigned address. Configuring the ip dhcp-server ping packets command with a value of
0 prevents the DHCP server from using ping packets as part of the IP address assignment process.
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
