Memory Tricks To Remember IEEE STP Designations

The INE(yes, I’m adapting the new abreviation of INE over IE for Internetwork Expert) blog has a nice post up about the different flavors of Spanning Tree.  What I really like about the posting is that memory tricks you can use to remember the letter designation of the IEEE specification.

802.1d(“Classic” Spanning Tree) – It’s dog-gone slow
802.1w(Rapid Spanning Tree) – Imagine Elmer Fudd saying ‘rapid’ as “wapid”
802.1s(Multiple Spanning Tree) – You add the letter ‘s‘ to nouns to make them plural(multiple)

I’ve always had trouble with tasks that refer to the flavor of STP by the IEEE designation*.  These simple memory tricks make it much easier to quickly decipher tasks that refer to the IEEE designation.

* This is a pet peeve of mine as I’ve never had someone in the “real world” say something like, “Go ahead and configure that switch to use 802.1w.”  If that ever happened I would just smile as I slowly twisted their nipples off.



  1. “As I slowly twist their nipples off” HAHHAA

  2. Hmmm. Let me think then, would that be 802.1w using Cisco Rapid-PVST+ or Cisco MST? Then again you might be multi vendor and have Switches that use 802.1s MST…..Ha Ha Ha Ha Haaaa

  3. 802.1w(Rapid Spanning Tree) – If you are from the Northeast it’s “wicked fast” (rapid)
