No subnet declaration for ethx

Linux DHCP

No subnet declaration for eth1 (no IPv4 addresses).
Ignoring requests on eth1. If this is not what
you want, please write a subnet declaration
in your dhcpd.conf file for the network segment
to which interface eth1 is attached.

This issue appears because Linux DHCP server doesn’t listen on eth1 network interface but there is a subnet declaration available for eth1. Append the following configuration in /etc/sysconfig/dhcpd file and then restart dhcpd service.

INTERFACES="eth0 eth1"
