Tag和Untag,tag是指vlan的标签,即vlan的id,用于指名数据包属于那个vlan,untag指数据包不属于任何vlan,没有vlan标记。 对于tag和untag是对于vlan的一个操作,若端口配置vlan 100 untag,那么带tag为100的数据在进入该端口是会被丢弃,出去是会被剥离;配置vlan 100 tag 进出都不会对该vlan做任何操作,只是开通了该vlan...
另一方面,动态VLAN则是根据每个端口所连的计算机,随时改变端口所属的VLAN。这就可以避免上述的更改设定之类的操作。动态VLAN可以大致分为3类: (1)基于MAC地址的VLAN(MAC Based VLAN) (2)基于子网的VLAN(Subnet Based VLAN) (3)基于用户的VLAN(User Based VLAN) 其间的差异,主要在于根据OSI参照模型哪一层的信息...
When the remote PPPoE server requires packets to carry a VLAN tag, the device can be successfully interconnected with the remote PPPoE server by binding the PPPoE client to a sub-interface. Perform the following operations to configure the PPPoE client function on a sub-interface: Configure a ...

When I inspect the Client it will display the VLAN ID and Flex VLAN ID as the proper VLAN despite the improper IP Address. (It would make more sense if the client was untagged to then get a VLAN45 IP) - see attached PNG for example of Client. They should have a 10.165....
VLAN tagged MACsec refers to frames that have a VLAN tag between the MAC source address and the MACsec ethertype. This VLAN tag is unencrypted (in the clear) so that intermediate devices between the MACsec endpoints can forward the MACsec frames based on this unencrypted VLAN tag. VLAN Ta...
