回答1:

switchport
allowed
vlan
使用这个命令在选定的接口上配置vlan组,使用no的形式恢复默认值。
语法
switchport
allowed
vlan
{add
vlan
[tagged
|
untagged]
|
remove
vlan}
no
switchport
allowed
vlan
1
add
vlan--所要添加的vlan标识符
2
remove
vlan--所要删除的vlan标识符
默认设置
所有的端口被分配到vlan
1
帧类型未加标记
命令模式
接口配置
命令的使用
1
如果交换机端口模式设置为trunk,那么你只能分配一个接口到vlan组作为未加标记的成员。
2
帧总是在交换机中被加标记。加标记和未加标记的参数用于告知交换机是否从进口处的帧保留或除去标记。
3
如果链接的另一端所有媒质网络设备和主机都不支持vlan,那么应该添加接口到这些vlan作为未加标记的成员。否则,有必要最多只添加一个vlan作为未加标记的成员,这应该符合本地vlan。
4
如果手动添加禁用列中的vlan
到那个接口,那么vlan自动从列中被删除。
switchport
native
vlan
使用这个命令为一个端口配置pvid,使用no的形式恢复默认值。
语法
switchport
native
vlan
vlan-id
no
switchport
native
vlan
vlan-id--一个端口的默认vlan
id。(范围:1-4094)
默认设置
vlan
1
命令模式
接口配置
命令的使用
1
如果接口不是vlan
1的成员,且你分配了它的pvid到这个vlan,那么接口将自动添加到vlan
1作为一个未加标记的成员。对于其他vlan,在你分配接口的pvid到那个组之前,接口必须先配置为未加标记的成员。
2
如故可接受的帧类型被设为all(所有),或交换机端口模式被设为hybrid(混合),那么pvid将被插入到所有未加标记的帧,流入进入端口。
第三个是一个基于交换机的命令
untagged
是一个端口的模式
