Clear understanding of the Ethernet TAG attributes

Thank you.

iIts very clear,  thanks.

Dear PengWei, Thanks for your great explanation regarding Tag Attributes.

Apart from the Tag attributes, I need some clarifications regarding Jumbo frame in Ethernet frame structure.

Would you please explain about Jumbo frame? As per Ethernet frames 1522 is the maximum byte when it carry both S-VLAN and C-VLAN an Ethernet frame can carry. But for Jumbo frame, Ethernet carry upto 9K+ bytes. But how it Ethernet frame structure can synchronize that? and also how NE can differentiate based on frame size? Does Jumbo frame carry additional header or byte to identify? 

Dear Raihan,

For the concepts and frame structure of Jumbo frame, please refer to http://support.huawei.com/gsbbs/bbs/27229.html.

Jumbo frame has a paticular type =Ox8870, and the EoS board can specify them from normal frames.

If you have other questions, please leave a message.
