[Background] As per below technical nodes, there is some improvement done in DHCP. RHEL 6.7 Technical Notes
Enhancement - BZ#1058674 With this update, the dhcpd daemon is able to handle dhcp option 97 - Client Machine Identifier (pxe-client-id), so it is now possible to statically allocate an IP address for a particular client based on its identifier, sent in option 97. example: host pixi { option pxe-client-id 0 00:11:22:33:44:
[Problem] In previous DHCP package (dhcp-4.1.1-43.P1) in RHEL6.6, we always received same IP address for adding new network interface with in existing network interface in case pxe calls through my Linux system reboot. In RHEL 6.10, the DHCP package(dhcp-4.1.1-61.P1) always received different IP address for adding new network interface with in existing network interface.
It seems different IP is assigned due to this identifier. So, we are checking a options to disable sending of pxe-client-id in pxe client configuration.
[question] Is there any way to disable or enable option 97(pxe-client-ID) in dhcp.
