The following are the phases undergone when a stack is created. Connect the intended main switch and slave switches through stack modules and dedicated stack cables. (Refer to H3C S3100-52P Ethernet Switch Installation Manual for the information about stack modules and stack cables.) Configure the IP address pool for the stack and enable the stack function. -
Page 3: Main Switch Configuration
Operation Manual – Stack-Cluster H3C S3100-52P Ethernet Switch Chapter 1 Stack When adding a switch joins in a stack, the main switch automatically assigns an IP address to it. The main switch automatically adds any switches that are newly connected to the stack through their stack ports to the stack. -

IP address. Since both stack and cluster use the management VLAN and only one VLAN interface is available on the S3100-52P switch, stack and cluster must share the same management VLAN if you want to configure stack within a cluster. -
Page 5: Slave Switch Configuration
Operation Manual – Stack-Cluster H3C S3100-52P Ethernet Switch Chapter 1 Stack join-in requests to the connected stack ports of all the switches connected with the device. This may cause switches not expecting to join in the stack to join in the stack automatically, affecting network stability. -

Page 12: How A Cluster Works
Note: After you create a cluster on an S3100-52P switch, the switch collects the network topology information periodically and adds the candidate switches it finds to the cluster. The interval for a management device to collect network topology information is determined by the NTDP timer. - Page 13 Operation Manual – Stack-Cluster H3C S3100-52P Ethernet Switch Chapter 2 Cluster neighbor information: device type, software/hardware version, and connecting port. In addition, it may provide the following neighbor information: device ID, port full/half duplex mode, product version, the Boot ROM version and so on.
- Page 14 Operation Manual – Stack-Cluster H3C S3100-52P Ethernet Switch Chapter 2 Cluster When an NTDP topology collection request is propagated in the network, it is received and forwarded by large numbers of network devices, which may cause network congestion and the management device busy processing of the NTDP topology collection responses.
- Page 15 Operation Manual – Stack-Cluster H3C S3100-52P Ethernet Switch Chapter 2 Cluster Before performing any cluster-related configuration task, you need to enable the cluster function first. Note: On the management device, you need to enable the cluster function and configure cluster parameters. On the member/candidate devices, however, you only need to enable the cluster function so that they can be managed by the management device.
- Page 16 Operation Manual – Stack-Cluster H3C S3100-52P Ethernet Switch Chapter 2 Cluster The management device and the member devices exchange handshake packets periodically. Note that the handshake packets exchanged keep the states of the member devices to be Active and are not responded.
- Page 17 Operation Manual – Stack-Cluster H3C S3100-52P Ethernet Switch Chapter 2 Cluster Cluster management requires the packets of the management VLAN be permitted on ports connecting the management device and the member/candidate devices. Therefore: If the packets of management VLAN are not permitted on a candidate device port connecting to the management device, the candidate device cannot be added to the cluster.

Page 18: Cluster Configuration Task List
Operation Manual – Stack-Cluster H3C S3100-52P Ethernet Switch Chapter 2 Cluster If you specify a destination IP address in the tracemac command, the switch will query its local ARP address table according to the IP address to find out the corresponding MAC address and VLAN ID. -
