Hi all,

I am having problems creating a gigastack of 3 switches (see attachment). The maximum amount of switches successfully working together are 2. When i connect the third switch via gigastack gbic, the link will flap on the center switch.

I tried different configurations but wasn't able to successfully interconnect the three switches. All three switches have the same software version, and there are no exciting stp configurations on any of the gbic if's. The rootswitch exists further down the "road".

The only difference i see with other working gigastacks i have installed before, is the difference of the g0/X intefaces between the switches, i am using g0/1 on sw1, g0/2 on sw2 and g0/1 on sw3.

Does anyone have any tips or tricks regarding this issue?
