Recommended Stack Deployment Scenarios

Recommended Stack Deployment Scenarios

Scenario 1: The Stack System Operates on Aggregation Switches

This is the most common scenario when aggregation switches set up a stack system, as shown in Figure 3-26.

In this scenario, each switch in a stack connects to a core device through Eth-Trunk. The stack system simplifies management of aggregation devices and improves uplink reliability of access devices.

Scenario 2: The Stack System Operates on Access Switches

This is the most common scenario when Layer 2 access switches set up a stack system, as shown in Figure 3-27.

In this scenario, each switch in a stack connects to an aggregation device through Eth-Trunk. The stack system simplifies management of and improves uplink reliability of access devices.

Scenario 3: The Stack System Operates on an Access Ring

This scenario rarely occurs. Figure 3-28 shows the networking of this scenario.

In this scenario, multiple stack systems form a ring through Eth-Trunk, and one stack system connects to aggregation switches through Eth-Trunk. This scenario reduces the number of management IP addresses of access devices.

Recommendations

Scenario 2 or Scenario 3 is preferred over Scenario 1.

NOTE:
To ensure stack reliability and bandwidth, you are advised to do as follows:
  • Ensure that each member device connects to the core device through an uplink port. This connection prevents upstream traffic forwarding from being affected when any member device fails.
  • When using multiple devices to set up a stack, ensure the same stack bandwidth between any two devices. Otherwise, the bandwidth of the stack system is the minimum stack bandwidth.
