二、配置：
SW1:
interface Vlanif20
ip address 192.168.20.2 255.255.255.0
vrrp vrid 1 virtual-ip 192.168.20.1
vrrp vrid 1 priority 120
#
interface Vlanif30
ip address 192.168.30.2 255.255.255.0
vrrp vrid 1 virtual-ip 192.168.30.1
vrrp vrid 1 priority 120
#
interface Eth-Trunk1
port link-type trunk
port trunk allow-pass vlan 20 30
#
interface GigabitEthernet0/0/1
eth-trunk 1
#

#
三、测试：
1.
2.
3.
四、收集命令：
1.display eth-trunk 1 查看聚合端口状态
2.display trunkmembership eth-trunk 1
3.display vrrp interface vlan 20 查看VLAN20的VRRP信息下载本文
