The backup file of the network card takes effect.

System: centos6.x

A segment is 192.168.199.1

A segment is 192.168.1.1

2 network segments, a network card, all effective, what's going on?

Group friends say: eth0:0 eth0:1 can be configured with many network segments. But I'm not like that.

This is because I have two configuration files in/etc/sysconfig/network-scripts/. Yeah, two profiles, both working.

ifcfg-eth0 is segment 199.

ifcfg-eth0.bak-1-wangduan is a segment 1.

And so, the configuration file takes effect, hehehe la

Here's what I'm looking for in ifcfg-eth0.bak-1-wangduan:

DEVICE=eth0
