ip dhcp-server ping timeout
Use the ip dhcp-server ping timeout command to specify the interval (in milliseconds) the DHCP server
will wait for a response to a transmitted DHCP ping packet. The DHCP server transmits ping packets
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 return to the default timeout interval.
Syntax Description
Specifies the number of milliseconds (valid range: 1 to 1000) the DHCP server will
wait for a response to a transmitted DHCP ping packet.
Default Values
By default, the ip dhcp-server ping timeout is set to 500 milliseconds.
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.
Usage Examples
The following example configures the DHCP server to wait 900 milliseconds for a response to a
transmitted DHCP ping packet before considering the ping a failure:
(config)#ip dhcp-server ping timeout 900
