Page 42: Stack Formation
Chapter 2: VCStack Overview Stack Formation As previously mentioned, a VCStack always contains a stack (active) master and a stack member (backup). To be part of a stack, a switch must connect to the other potential stack member via dedicated stacking ports. See Figure 16. - Page 43 AT-DC2552XS / L3 Enterprise Core Switch Installation Guide The master is the switch with the lowest priority setting, or if the priority settings are equal, the switch with the lowest MAC address will become the stack master. When a stack member is initially booted, its priority value defaults to 128.
