Configure Stack Settings on a Cisco
Business 350 Series Switch through the
Command Line Interface (CLI)
Objective
This article provides instructions on how to configure stack settings through the Command Line
Interface (CLI) of your Cisco Business 350 series switch.
Introduction
Stacking allows you to expand your network capacity without the hassle of managing multiple
devices. Stackable switches can be added or removed from a stack as needed without affecting
the overall performance of the stack. Depending on its topology, a stack can continue to transfer
data even if a link or unit within the stack fails. This makes stacking an effective, flexible, and
scalable solution to expand network capacity.
By default, a switch is always stackable, but has no port configured as a stack port. All the ports in
the devices are configured as network ports by default. A device without any stack port can be
thought of as the active device in a stack of only itself or as a standalone device. To stack two or
more switches, you can reconfigure the desired network ports as stack ports in the switches and
connect them with the resulting stack ports in a ring or chain topology.
The units or switches in a stack are connected through stack ports. Stacked switches are then
collectively managed as a single logical device. In some cases, stack ports can become members
in a stack of Link Aggregation Groups (LAGs) increasing the bandwidth of the stack interfaces.
Some of these stacking terms may be unfamiliar to you. For further explanation, check out
Business: Glossary of New
A stack provides the following benefits:
Network capacity can be expanded or reduced dynamically. By adding a unit, the
administrator can dynamically increase the number of ports in the stack while maintaining a
single point of management. Similarly, units can be removed to decrease network capacity.
The stacked system supports redundancy in the following ways:
- The Standby unit becomes the active of the stack if the original active fails.
- The stack system supports two types of topologies: Chain and Ring. Ring topology is more
reliable than a chain topology. The failure of one link in a ring does not affect the function of the
stack, whereas the failure of one link in a chain connection might cause the stack to be split.

  • Page 1 Command Line Interface (CLI) Objective This article provides instructions on how to configure stack settings through the Command Line Interface (CLI) of your Cisco Business 350 series switch. Introduction Stacking allows you to expand your network capacity without the hassle of managing multiple devices.
  • Page 2 Connect the Switches Step 1 Determine the stack mode that you would want to configure. The options are: Chain - Each unit is connected to the neighboring unit, but there is no cable connection between the first and last unit. This is the default stack mode. The image below shows a chain topology of a four-unit stack: Ring - Each unit is connected to the neighboring unit.
  • Page 3 Step 2 Connect one end of the Small Form-Factor Pluggable (SFP) cable that came with your device into the SFP+, XG3, or XG4 port of your switch. In this example, the cable is connected to XG3 port of the switch. Step 3 Connect the other end of the SFP+ cable into the SFP+, XG3 or XG4 port of your switch.
  • Page 4 Follow these steps to configure stack settings on the Active switch: Step 1 Log in to the console of the first switch. The default username and password is cisco/cisco. If you have configured a new username or password, enter the credentials instead.
  • Page 5 The available commands may vary depending on the exact model of your device. In this example, CBS350-48MP switch is used.The hostname of the Standby switch is CBS350-2. Step 2 Enter the Global Configuration mode of the switch by entering the following: configure CBS350-1# Step 3...
  • Page 6 Configure Stack Settings on the Standby or Member Switch Step 1 Log in to the console of the second switch. The default username and password is cisco/cisco. If you have configured a new username or password, enter the credentials instead.
  • Page 7 configure CBS350-2# Step 3 To enter the context of the specified stack unit or all stack units, enter the stack unit command in the Global Configuration mode by entering the following: stack unit [unit-id | all] CBS350-2(config)# In this example, stack unit 1 is used. Step 4 Enter the stack configuration command to configure the stack ports and unit ID after reboot by entering the following:...
  • Page 8 copy running-config startup-config CBS350-2# Step 9 (Optional) Press Y for Yes or N for No on your keyboard once the Overwrite file [startup-config]… prompt appears. Step 10 Reload the switch to apply the configured stack settings by entering the following: reload CBS350-2# Important: When a switch is reloaded, the running configuration file is deleted.
  • Page 9 Step 2 In the Privileged EXEC mode of the switch, use the show stack command to show the stack settings on the switch by entering the following: show stack CBS350-1# In this example, the configured unit 2 is now known as the Standby switch of the stack. Step 3 Enter the show stack links command to show the stack links on the switch by entering the following:...
  • Page 10 stack links details - Displays the stack links information for an entire stack with details. Step 4 (Optional) To access the Standby switch, enter the stack unit ID of the switch in the Global Configuration context by entering the following: In this example, the configured Standby switch is now accessible as unit 2.
