    Network Unstable

    Last year the school was updated now we have a 3Com Baseline Switch 2924-SFP Plus as the back bone and a number of Baseline 2226 Plus.

    Recently (or it may be older) there were a number of problems relating to Login, Profiles etc. When I have checked the switches I fould the following error:

    "STP TOPOLOGY UNSTALBLE"

    In each case the fault seems relate to login time (about 9.00) each day.

    Any idea?

    at a guess something to do with spanning tree protocol might be worth furning it on/off depending on current state
