Command Manual (For Soliton) – Stack-Cluster
H3C S3100 Series Ethernet Switches
After a stack is created, the main switch automatically adds the switches
connected to its stack ports to the stack.
A slave switch quits the stack automatically when it is disconnected from the stack.
If the IP address of the management VLAN interface of the main switch (or a slave
switch) is not of the same network segment as that of the stack address pool, the
main switch (or the slave switch) automatically removes the existing IP address
and picks a new one from the stack address pool as its IP address.
Since both stack and cluster use the management VLAN and only one VLAN
interface is available on the S3100 switch, stack and cluster must share the same
management VLAN if you want to configure stack within a cluster.
