4：ip地址配置
###################################################################################
Interface add 2 //首先添加interface，此处代表的是：VLANID。
address 2 192.168.10.2/24 //对此VLAN ID 设置ip地址。
IP>confi

vlan1: mtu=1500 IPv4=192.168.1.2/24
vlan2: mtu=1500 IPv4=192.168.10.2/24
vlan3: mtu=1500 IPv4=192.168.100.3/24
ping命令的使用格式如下：
IP ping 192.168.100.141 L 100 C 50 I 2
IP ping 192.168.10.102 L 100 C 50 I 2
IP ping 192.168.1.101 L 100 C 50 I 2

上面的测试中：
是在192.168.100.73主机上面ping网桥上面的IP:192.168.100.103，其所接的vitesse端口为：port4.
网桥所接vitesse端口为：port5或者port6。其他方式是不能pingt通的。
上面的数据包可知，当数据经过port5或者port6时，会对数据包进行打标签处理。
6：其他VLAN组分析
####################################################################################
此项中IP进行了调整。没有对VLAN2和VLAN1进行ip地址设置。
IP>conf
Mode: router
vlan1: mtu=1500
vlan2: mtu=1500
vlan3: mtu=1500 IPv4=192.168.100.3
同时IP地址的设置时可有可无的，但是当需要通过telnet来访问vitesse switch的时候需要设置Ip地址。
VLAN配置没有变化，从上面的的VLAN配置中可知，我们配置了3个VLAN：
VLAN1，VLAN2，VLAN3，其中端口分配如下：
---- -------------------------------- -----
1 default 1-29
2 testVlan2 2,3
3 testVlan3 4-6 //4,5,6是同一个VLAN
其中port2和port3属于VLAN2，port4~port5属于VLAN3。
其中default，没有实际的意思。
只有属于同一个VLAN组的port时间才能通信。
下面的数据包是：当pC和网桥分别接到了端口port2和port3。或者接除了port2~port6之外的数据包也是可以的。
其中PC的ip地址为：192.168.10.73
