I have a ME-3400EG-12CS-M switch the ports 13 thru 16 have sfp's and are connection to other 3560 switches over fiber. The GIG 0/1 on the 3400 connects to the long haul sonet transport electrically. The IOS is Version 12.2(55)SE3. I can't ping or log into the 3400 unless I am at one of the 3560 switches hanging off of the NNI ports 13 thru 16. I think it is because the max number of NNI ports are 4 and I can't change the GIG 0/1 to a NNI port. Can I make config changes to the UNI port so that it will act like a NNI port with out upgrading the IOS to allow for more NNI ports?
