Abstract
The subject matter described herein includes methods and systems for providing accidental stack join protection. According to one embodiment, a method includes connecting stacking ports of a first switch that is a member of a first stack and a second switch that is a member of a second stack and thereby joining the first and second stacks. The configurations of the first stack and of the second stack are detected and it is determined whether the detected configurations indicate a configuration mismatch between the first and second stacks. In response to determining that the detected configurations relate to a mismatch, the automatic joining of the first and second stacks is inhibited and the first and second stacks are allowed to continue switching traffic with their existing configurations.
