提前规划堆叠方案。规划SwitchA的堆叠成员ID为1，SwitchB的成员ID为2。规划SwitchA作为主交换机，其堆叠优先级最高，为150。SwitchB的堆叠优先级为120。规划堆叠域编号（Domain ID）为10，不与网络中其他堆叠系统的域编号冲突。规划SwitchA和SwitchB用于堆叠连接的端口为10GE1/0/1～10GE1/0/4。
按照前期的规划，连接SwitchA和SwitchB之间的堆叠线缆。
先完成SwitchA的堆叠配置（SwitchA规划的优先级高）。
# 配置SwitchA的堆叠优先级为150，Domain ID为10。缺省情况下，设备的堆叠成员ID为1。此处默认SwitchA的堆叠成员ID为1，无需配置。 system-view
