需求:linux as 4.2系统下实现一个网卡可以网管多个ip段的设备(多个ip段都在同一个vlan中)
分析:实现这个需要在一块网卡上面绑定多个网段的ip
解决:
1、增加一个虚拟的网卡文件
cd /etc/sysconfig/network-scripts/
cp ifcfg-eth1 ifcfg-eth1:0
2、编辑eth1:0,改变其中的ip地址、设备名称等信息
vi ifcfg-eth1:0
# Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express
DEVICE=eth1:0 #这里更改为新的虚拟设备名称
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.x.250 #这里更改为新网段的ip
NETMASK=255.255.255.0
HWADDR=00:17:x.x:B1:C1 #这里不能更改
然后保存ifcfg-eth1:0文件
3、重启网络服务
[root@xxxx network-scripts]# service network restart
Shutting down interface eth0: [ OK ]
Shutting down interface eth1: [ OK ]
Shutting down loopback interface: [ OK ]
Setting network parameters: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]
Bringing up interface eth1: [ OK ]
4、测试
[root@xxxx network-scripts]# route

192.168.x.0 * 255.255.255.0 U 0 0 0 eth1
default 172.x.x.1 0.0.0.0 UG 0 0 0 eth0
