Your mnemonic trick to remember the OSI layer

jibbajabbajibbajabba Posts: 4,317Member
This is something I never really forgotten (which probably helps when starting to study for the CCNA) is the OSI model ..

I thought, why don't we all share how we remember them :P

So here is my one (top to bottom)

[Application] All
[Presentation] Pros
[Session] Search
[Transport] Top
[Network] Notch
[Data Link] Donut
[Physical] Places

The CBT Nugget one is not too bad either (Bottom to Top)

[Application] Away
[Presentation] Pizza
[Session] Sausage
[Transport] Throw
[Network] Not
[Data Link] Do
[Physical] Please

    There's been a couple of threads with a lot of those:
    http://techexams.net/forums/viewtopic.php?t=3740

    And yes, I did find those by searching for "ninja turtles" in the search icon_lol.gif

    I think the CBT Nuggets one is a really good one for beginners just starting out on the OSI Model. Give it a little practice and those layers will be ingrained into your head.

    I don't think so......... :)

    I found that it was much easier to remember all the layers, and their order, once I began to grasp an understanding of what each does and what types of devices (or functions) reside in each. The mnemonic devices didn't do much for me. Well, there was one, but I don't think anyone's going to want to hear it. . .

    So what's a layer 3 switch? Or layer 4-7 inspection? Not everything is only TCP/IP.

    But hey what do I know.

    K, advertise yourself as a session-layer protocol developer and see who bites.

    Brilliant!!

    btw TryPingingTheServer if you're going to make statements like that how about backing them up with your source if the OSI model is so obsolete then why is it still used today and found in literally every text book on networking..

    not strictly OSI but:

    Don't = DATA
    Smoke = SEGMENT
    Pot = PACKET
    For = FRAME
    Breakfast = BITS

    Not to continue this but... SIP

    How many thousands of hours are put into that one protocol? Oh and it's on the session layer of the OSI model. You can also argue it's on the TCP/IP Application layer as well.

    Point is, the OSI model is still a very important model used to describe almost anyting in networking. The TCP/IP model (formerly the DOD model) is far less common even though the TCP/IP protocol stack was developed using it.

    Yeah the ignorance is mind-blowing. TCP/IP may be the most popular protocol but there are dozens of other protocols still in use, and having a common standard to map them against is important.

    I'm not. I'm currently in the world of FCP to see whether we should go FCoE. We've got a fairly sizeable FC-SW SAN at the moment but somebody up high has heard of FCoE so now I've got to go look at that even though its not even ready.

    At the end of the day, the proposal will be shot down because the price of all the gear. Ah well. Back to FC-SW :)

    Ah yes, you're experiencing this problem.

    The draft of FCoE isn't even due until this month. What does he want you to use for hardware? I mean Emulex/QLogic and Cisco have demonstrated it as working against the Nexus 5000, but it's not like the configurations with those HBAs/switches are generally available, let alone supported by anyone. Even Brocade has only committed to FCoE "by the end of the year".

    Talk about being an early adopter (and on one of your most critical components in the data center). I love CIOs like this. icon_lol.gif

    P.S. Just curious, how many nodes on your switched fabric?

    Just over 100. Its an IBM shop which means IBM DS arrays, nSeries branded NetApps, TSM libraries, iSeries running a combination of legacy AS/400 systems and newer backends, pSeries running the front ends and xSeries running some standalone Windows services + ESX. Just replacing the directors would cost a fortune.

    IBM need to get a bit more colour in their gear. The only thing I'm missing a zSeries :)

    Gah. You can really date when I started messing around with IBM gear by what I call them.
