I have a site administrator that was exploring his network using CNA yesterday. The network consists of a 3750 "core", a couple of 3550-12G distribution switches, and several access switch stacks. The access switch stacks are configured as switch clusters. He managed to do two things:
1) While connected to one of the access switch clusters, he managed to add all of the switches that were not configured as part of a cluster to that cluster. This icluded the 3750 stack and the distribution switches.
2) He managed to configure the switch from NVRAM. In other words, the saved config overwrote the running config.
Does anyone know how he could have done this? I rarely use CNA.
