VTP

Is it vlan trunkING protocol or vlan trunk protocol?

I’ve seen both terms used. When I renewed my CCNA in 2006, I had a CCSI tell me specifically that is was VLAN TRUNK protocol. He emphasized that point a few times.

As I’ve started working through the BCMSN study materials and the CCIE Routing and Switching Exam Cert Guide, I’m seeing VLAN TRUNKING protocol. So which is it?

Here are two links with an argument for either side…

“Trunk”

“Trunking”

  1. I’m enrolled in the Cisco Networking Academy and am currently taking their new CCNA Exploration courses. Their LAN Switching concepts refers to it as “VLAN TRUNKING PROTOCOL”.

  2. @ Sgee,

    That’s good to know. I’ll put my faith in their current curriculum.

  3. I would go with the Vlan Trunk Protocol.
    I would consider the opposite to be Dynamic Trunking Protocol (DTP), having the “ing” refer to trunk forming.

  4. I Confirm, same as DTP, dynamic/vlan trunkING protocol 🙂

  5. oh wow… two contradicting answers within 20 minutes of each other…

    I know this question came up on the CCNA exam, but I wonder how relevant it is to the NP/IE exams. How important is that ING when discussing VTP outside of the CCNA exam?

  6. @Tassos and lessaid,

    Since you both brought up DTP, page 45 in the CCIE Routing/Switching Exam Certification Guide introduces DTP as Dynamic Trunk Protocol.

    Does Cisco still get this nit picky in the professional/IE level exams? Do they ask you to list what a specific acronym stands for and offer “trunk vs trunking” as two possible answers?

  7. I haven’t met such a question yet.
    And if there was such a question, i guess it wouldn’t include both “trunk” and “trunking” as possible answers.

    But, if you meet it, just send a “nice” comment to Cisco 😉
