基于802.1Q的VLAN帧格式 Type:长度为2字节,取值为0x8100,表示此帧的类型为802.1Q Tag帧。 PRI:长度为3比特,可取0～7之间的值,表示帧的优先级,值越大优先级越高。该优先级主要为QoS差分服务提供参考依据(COS)。 VLAN Identifier (VID) : 长度12bits,可配置的VLAN ID取值范围为1～4094。通常vlan 0和vlan 40...
在802.1Q中规定2字节的TPID(Tag Protocol Identifier)的EtherType值为0x8100。如果一个帧中的TPID的EtherType值是0x8100,则表示该帧是带Tag的帧。对于QinQ报文的EtherType值,不同的设备制造商有不同的设置。华为公司采用默认的0x8100,有些设备制造商采用0x9100,为了实现华为公司的设备与其他制造商的设备互通,需要...

Insertion of the802.1Q VLAN tag(four octets) into an Ethernet-II frame, with a typical VLAN arrangement of a TPID EtherType value of 0x8100. AQinQarrangement would add another four octets tag containing two octets TPID using various EtherType values. Triple tagging QinQinQ has three four-octe...
The figure below shows a typical VLAN arrangement with a TPID EtherType value of 0x8100. AQinQarrangement would add another 32-bit tag with 16-bit TPID using various EtherType values. Triple Tagging QinQinQ has three 32-bit tags besides the original 16-bit EtherType field. ...
Step 2: Change ethertype from 8100 to 88a8 as shown above.Step 3: Apply the change. Step 4: Now login to NE and check the command sent from the server: Here is what happens on the NE when it receives the request from PWSM:...
