There is a discovery of IP fluctuations.

Workaround:

Add in/etc/sysctl.conf

Net.ipv4.conf.default.arp_ignore = 1

Meaning: Determine the different ways in which the response received by the ARP protocol requires 0-(the default) to represent any destination IP address, configure any interface. 1-Reply only the destination IP address is configured on the local address of the incoming interface.
Net.ipv4.conf.all.arp_ignore = 1 Meaning: Ibid.

After Sysctl-p
and add the MAC address in the/etc/sysconfig/network-scripts/ifcfg-eth file, which can be viewed ifconfig.
