What is the maximum number of VLANs that can be supported with one VLAN tag field?
The maximum number of VLANs that can be supported with one VLAN tag field is 4096. This is because the VLAN tag field is 12 bits in length, allowing for 2^12 (4096) different VLAN IDs. Therefore, the correct answer is 4096.
this should be 4096 showing in different documents
Answer A: 4096 (CCNA)
answer D = The Tag Protocol Identifier is set to 16 bits. In the CCNA certification it is said that it's not possible to have more than 4096 VLANs
A - 4096
4,094 Under IEEE 802.1Q, the maximum number of VLANs on a given Ethernet network is 4,094 (4,096 values provided by the 12-bit VID field minus reserved values at each end of the range, 0 and 4,095).
A. 4094 The Total possible are 4096, VID of 0 is used to identify priority frames, and value 4095 (FFF) is reserved, so the maximum possible number of supported VLANs is 4,094
Ethernet switches that have VLAN enabled use Ethernet frames with the VLAN TAG field added. The VLAN TAG is a 12-bit field that can address up to 4096 VLANs. A switch reads the VLAN tag and forwards the Ethernet frame to the port assigned to the VLAN ID, or to the next switch when required.
