Hi guys. I am new with Enterasys. I have 2 cisco routers connected to a stacked c3 switch. we recently upgraded from firmware 1.02.01.0004 to 6.42.03.0004. Now the switch is hanging every 12 hours. After shutting and unshutting the 2 ports connected to theCisco routers, everything works. We have been doing this for 3 days and I have checked my configurations. Please help.
