HP 7000 dl Router Ip dhcp-server ping timeout milliseconds, Config#ip dhcp-server ping timeout

SROS Command Line Interface Reference Guide Global Configuration Mode Command Set

ip dhcp-server ping timeout <milliseconds>

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

<milliseconds>	Specifies the number of milliseconds (valid range: 1 to 1,000) the DHCP server
	will wait for a response to a transmitted DHCP ping packet.

Default Values

<milliseconds> 500 milliseconds

Command Modes

(config)# Global Configuration Mode required

Functional Notes

Before assigning an IP address to a requesting client, the Secure Router OS 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
