实验要求：
1.局域网存在vlan10和vlan20两个业务vlan，ip网段分别对应192.168.1.0/24和192.168.2.0/24
2.业务vlan可以在所有链路上传输数据
3.sw1和sw2之间的直连链路上配置静态链路聚合实现链路冗余，并提高链路带宽
4.sw3为某接入点二次交换机，与汇聚交换机sw1和sw2运行MSTP来对vlan10和vlan20的流量进行负载分担，要求vlan10的流量优先从sw1转发，vlan20的流量优先从sw2转发，当链路故障，sw1和sw2互为备份
5.sw4为另一接入点二次交换机，使用Smart-link对上行链路进行备份，要求Smart-link组1引用MST实例1（映射vlan10）的流量经过sw1的链路访问上行设备。而Smart-link组2引用实例2（映射vlan20）的流量经过sw2链路访问上行网络，组1和组2分别在vlan100和vlan200内发送和接受Flush报文，要求当Smart-link主链路故障恢复后，端口角色能够自动恢复。
6.sw1和sw2作为汇聚层网关，运行VRRP，vlan10，使用sw1作为VRRP的主网关，vlan20使用sw2作为VRRP的主网关。
7.要求终端pc接入网络后，能够立即转发数据，当连接pc的端口收到BPDU后立即关闭
8.在sw1上配置SSH服务，要求只有vlan10能够远程登陆sw1，登陆用户名和密码都为runtime
9.在sw2上配置SNMP，要求只有pc6能够使用SNMP管理sw2
