I Have 4 switches 2950 connected each one with the others three and one of them as a root.
1.- Can I activate UplinkFast in order to provide fast convergence in the network access layer after a spanning tree topology change?
2.- Should I activate UplinkFast only on the three wich are not the root?
3.- Can I have problems with this configuration (in terms of uncontrolled loop)
4.- What happen if the root switch is going down? IN that case one of the other three switches with UplinkFast enabled will be the new root.
