Last Monday my stack of 6248's rebooted for no reason. I saw that they had gone up and down several times until I could get there to manaully power cycle them.
Since then I have had terrible latency. The only way I could get consistent pings was to enable portfast and enable BPDU Flooding in spanning tree global settings but I still feel there could be something wrong with the config. Was hoping you guys could help me out.
