  1. Hi Rene,
    Which’s standard of RFC that I can follow when learning the TACACS+?
    Many thanks!

  2. Hello Thinh

    The original TACACS is defined in RFC 1492 as it is an open IETF standard. TACACS+ however was developed by Cisco so it has no corresponding RFC. Cisco developed it as an open standard so many vendors can and do use it.

    There is however a Cisco RFC TACACS+ Draft available on the IETF web site that you can check out. There are also additional drafts that have been added, the most recent of which can be found here.

    I hope this has been helpful!


  3. oh, thank you so much, i looked it out :slight_smile:

  4. Hello

    Can you please explain what you mean at the beginning of the lesson, that port security cannot prevent the connection of a Wi-Fi router to the switch? Could not we just configure the switch to accept only specific MAC addresses on its interfaces via port security? How is NAT also affecting the whole process? Thank you in advance!


  5. Just a quick real work question. Im wondering about the ramifications in a windows domain environment. If a host machine is booted i assume all traffic from machine is blocked prior to the login. I assume the windows SSO can also act as a 802.1X supplicant. If so then i get my windows logon AND network access at the same time ? How does this work in a scenario if one user logs off and a second logs on ? or if (in a windows 7+ environment a “switch user” is performed? Any light you can shed on how 802.1x works with AD login, login scripts group policy etc would be appreciated.

    Thanks so much!
