being configured the PPS protection on 2 EMS4 (version 7.15) boards as no-revertive, the fiber of the port 1 of the working board faild and it is commuted to the port 1 of protection, when recovers the fiber, it is commuted to the port 1 working from the T2000. after some minutes of carrying out this commutation the
fiber of the port 1 of the working board faild again and the service presents affectation because it doesn't commute to the protection port. the version SSN3GSCC board is 18.104.22.168P01 and of the T2000V200R007C03SPC003
when forcing the commutation from the T2000 in the PPS protection , the state of the protecion changes to "normal." to "forced switching(protection to working) " (check presentation), this state should be changed again to "normal" for a new commutation, this is made giving right click on the lash “Switching Status” and to select clear (check presentation). the state in the
lash “Switching Status” changes to "normal" (check presentation)
when carrying out the commutation from the T2000 the lash “Switching Status” it shows the port as "forced switching(protection to working) ", this state should changes to "normal" for a new commutation.
it should be kept in mind that when the commutation is made from the T2000 on the PPS protection, this it was executed in all the ports and in case the suitable procedure is not made previously, any port that failed in the working
board ethernet would affect the service because it would not commute
