Have you bind g0/0/1 and g0/0/3 to one Eth-trunk?

If not, g0/0/1 and g0/0/3 will be a loop, then one port will shutdown.

If you keep the loop, you can excute stp disable in two S5700, and see whether the port will up or not.

thanks a lot for your help, but there is not an STP issue or a loop.

before I have reported the issue I made many test in order to be sure that there is not a configuration problem,



let´s suppose that there is a loop, so way the conections to the routers don not turn on?, becouse the cpu utilization is to hight? well its possible but there is nor the roort couse.



I belive that is a bug in the simulation´s software, however only to show you that the problems does not the STP or a loop problem I created a new topology with single interconection between switches, were I disabled the STP, and I have got the same issue.

in the attached you can see the results.

best regards.

this is the new topology.

If you think it is a software issue, you can use the newest version.

Is there some special configuration on your devices? I simulate your scen and ports are normally up.

thats good!!!!

I am running the software versión V100R002C00 it seems to be that is the newest versión, please tell me what versión did you used.

I have a good news, I found other way to  turn on the ports, only put a hub in the middle of interconection switches,

and now all ports are up.
