HP 7000 dl Router manual Ip dhcp-server ping packets #packets, Config#ip dhcp-server ping packets

SROS Command Line Interface Reference Guide Global Configuration Mode Command Set

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

<#packets> 2 packets

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. 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 4 ping packets before assigning an address:

(config)#ip dhcp-server ping packets 4
