Operation Manual – Stack-ClusterH3C S3100-52P Ethernet Switch Chapter 1 Stack1-2z When adding a switch joins in a stack, the main switch automatically assigns an IPaddress to it.z The main switch automatically adds any switches that are newly connected to thestack through their stack ports to the stack.1.2 Main Switch ConfigurationThe main switch configuration includes:z Configuring the IP Address Pool and Creating the Stackz Switching to Slave Switch View1.2.1 Configuring the IP Address Pool and Creating the StackTable 1-1 Configure the IP address pool and create the stackOperation Command DescriptionEnter system view system-view —Configure an IPaddress pool for astackstacking ip-poolfrom-ip-addressip-address-number[ ip-mask ]Requiredfrom-ip-address: Start address of the IPaddress pool.ip-address-number: Number of the IPaddresses in the IP addresses pool. Apool contains 16 addresses by default.ip-mask: Mask of the IP address pool.By default, the IP addresses pool is notconfigured.Create a stack stacking enable RequiredNote:Remove the IP address configured for the existing Layer 3 interface first if you want tocancel the stack-related configuration, otherwise, IP address conflicts may occur.As for the stack-related configurations performed on a main switch, note that:z After a stack is created, the main switch automatically adds the switchesconnected to its stack ports to the stack.z If a stack port connection is disconnected, the corresponding slave switch quitsthe stack automatically.z The IP address pool of an existing stack cannot be modified.z To add a switch to a stack successfully, make sure the IP address pool contains atleast one unoccupied IP address.
