    The 802.1q standard is of course an alternative to Cisco's ISL, and one that all vendors implement on their network equipment to ensure compatibility and seamless integration with the existing network infrastructure.
    Amazingly enough, the 802.1q tagging method supports a whopping 4096 VLANs (as opposed to 1000 VLANs ISL supports), a large amount indeed which is merely impossible to deplet in your local area network. The 4-byte tag we mentioned is inserted within the existing Ethernet frame, right after the Source MAC Address as illustrated in the diagram below:
    As with all 'open standards' the IEEE 802.1q tagging method is by far the most popular and commonly used even in Cisco oriented network installations mainly for compatability with other equipment and future upgrades that might tend towards different vendors.
    Because of the extra 4-byte tag, the minimum Ethernet II frame size increases from 64 bytes to 68 bytes, while the maximum Ethernet II frame size now becomes 1522 bytes. If you require more information on the tag's fields, visit our protocol page where further details are given.
