Volume 9-Network Application / Chapter 49-DHCP Server Configuration DHCP Server Configuration Commands The following is sample of configuring the lease, in address pool "pool1", to 1 hour. DGS6600#configure terminal DGS6600(config)#ip dhcp pool pool1 DGS6600(config-dhcp)#lease 0 1 Configuring the DHCP Bootfile The boot file is used to store the boot image for the DHCP client. Use the following command is possible to specify the name of the default boot image for a (DHCP) client. The boot image can be located on the same DHCP server or other network servers. To specify a boot file for the DHCP client, use the following command in DHCP pool configuration mode: Command boofile URL Explanation Use this command to specify the name of the default boot image for a Dynamic Host Configuration Protocol (DHCP) client. The boot image can be located in the same DHCP server or other network servers. The following example specifies mdubootfile as the name of the boot file for DHCP pool1. DGS6600#enable DGS6600#configure terminal DGS6600(config)#ip dhcp pool pool1 DGS6600(config-dhcp)#bootfile \dgs-6600\bootimage\mdubootfile.bin Configuring DHCP Ping Packets By default, the DHCP Server pings a pool address twice before assigning a particular address to a requesting client, with the DHCP server waiting 500 milliseconds before timing out the ping packet. If the ping is unanswered, the DHCP Server assumes (with a high probability) that the address is not in use and assigns the address to the requesting client. To change the number of ping packets and the length of time before a timeout, use the following command in global configuration mode: Command ip dhcp ping packets COUNT ip dhcp ping timeout MILLISECONDS Explanation User this command to specify the number of packets that the DHCP server will send as a part of the ping operation. Use the no form of this command to prevent the server from pinging pool addresses. Use this command to specify how long the DHCP server will wait for the ping reply from a pool address. Use the no form of this command to restore the wait time for the ping reply back to the default value (500ms). DGS-6600 Configuration Guide 493
