What field is consisted of 6 bytes in the field identification frame in IEEE 802.1Q?
Click on the arrows to vote for the correct answerA. B. C. D.
The field identification frame in IEEE 802.1Q is also known as the VLAN tag or header. It is added to Ethernet frames to identify the VLAN membership of the frame. The field identification frame is 4 bytes long, and it consists of four fields:
Tag Protocol Identifier (TPID) - This field identifies the protocol used for tagging. The value for IEEE 802.1Q is 0x8100.
Priority Code Point (PCP) - This field is 3 bits long and is used to prioritize traffic. It allows switches to prioritize traffic based on its importance.
Canonical Format Indicator (CFI) - This field is 1 bit long and is used to indicate whether the MAC address is in canonical format or not.
VLAN ID (VID) - This field is 12 bits long and is used to identify the VLAN to which the frame belongs. It allows switches to forward traffic to the correct VLAN.
None of the options (A. SA, B. DA, C. FCS, D. SOF) given in the question match any of the fields in the IEEE 802.1Q VLAN tag. Therefore, the answer is none of the above.
