xen 3.1 create vlan

1.         创建网桥

[root@localhost ~]# brctl addbr xenvbr11

[root@localhost ~]# brctl stp xenvbr11 off

[root@localhost ~]# brctl setfd xenvbr11 0 //set forward delay time

[root@localhost ~]# ip link set xenvbr11 up

2.         创建vlan

[root@localhost ~]# vconfig set_name_type DEV_PLUS_VID_NO_PAD

[root@localhost ~]#vconfig add peth0 11 //在peth0上创建vlan

[root@localhost ~]# ip link set peth0.11  address fe:ff:ff:ff:ff:ff

[root@localhost ~]# ip link set peth0.11 up

3.         把vlan加入到网桥中

[root@localhost ~]# brctl addif xenvbr11 peth0.11

4.         创建端口配置文件

[root@localhost ~]#  cd /etc/sysconfig/network-scripts/

[root@localhost network-scripts]# cat ifcfg-peth0.11

DEVICE=peth0.11

TYPE=Ethernet

ONBOOT=yes

MACADDR=fe:ff:ff:ff:ff:ff

VLAN=yes

IPADDR=192.168.5.1

NETMASK=255.255.255.0

VLAN_NAME_TYPE=DEV_PLUS_VID_NO_PAD

BRIDGE=xenvbr11

 

[root@localhost network-scripts]# cat ifcfg-xenvbr11

 

DEVICE=xenvbr11

TYPE=Bridge

DELAY=0

STP=off

ONBOOT=yes

[root@localhost ~]# cat /etc/init.d/xenvlansetup

 

#!/bin/bash

case "$1" in

        xenbridge=`brctl show | grep xenvbr | awk '($4 == ""){print $1}' 2>&1`

        for bridge in $xenbridge

        do

            device="peth0"

            vlanId=${bridge:6}

            vlanDevice="peth0.${vlanId}"

 

            vconfig add $device $vlanId 2>&1

            ip link set $vlanDevice address fe:ff:ff:ff:ff:ff 2>&1

            ip link set $vlanDevice up 2>&1

            brctl addif $bridge $vlanDevice 2>&1

        done

        exit 1
