DHCP not responding to BOOTP client request messages.

[趙 良基]

1.       When DHCP Server enabled as Dynamic/Static IP Assignment and only Dynamic(DHCP Server) pools are enabled,
  DHCP Server  not responding with BOOTP Reply on receiving BOOTP request message.

When Static IP/IP port binding pools are enabled with respective pools, DHCP Server responded to received BOOTP request.
This issue occurs only with Dynamic IP Assignment.

So I add

allow bootp;

range dynamic-bootp 192.168.127.70 192.168.127.99;

to dhcpd.conf,it can response the bootp client ,but the bootp not use this response ip.

I attach the wireshark file is use tool tftpd32 dhcp server to response the bootp client and client use normal,

And linux dhcp server packet file.

 

dhcpd.conf:

 

authoritative;

allow bootp;

 

subnet 192.168.127.0 netmask 255.255.255.0 {

}

 

subnet 192.168.127.0 netmask 255.255.255.0 {

        default-lease-time 86400;

        max-lease-time 446400;

        range 192.168.127.22 192.168.127.55;

        range dynamic-bootp 192.168.127.70 192.168.127.99;

        option broadcast-address 192.168.127.255;

        option routers 192.168.127.0;

        option domain-name-servers  192.168.127.254;

}
