Application Scenarios for Stacks

Application Scenarios for Stacks

Bandwidth Expansion and Inter-Device Link Redundancy

As shown in Figure 1-29, when the network expands and higher uplink bandwidth is required, you can connect a new switch to the original one using stack cables so that the two switches can set up a stack. Then bundle physical links of the member switches into a link aggregation group to increase the uplink bandwidth.

Downstream switches connect to the stack through inter-device Eth-Trunk links. This networking implements redundancy between devices and links, enhancing network reliability.

Simplifying Network Topology

As shown in Figure 1-30, two switches are virtualized into a logical switch. This simplified network does not require Multiple Spanning Tree Protocol (MSTP) or Virtual Router Redundancy Protocol (VRRP), so network configuration is much simpler. Inter-device link aggregation also speeds up network convergence and improves network reliability.

Long-Distance Stacking

Long-distance stacking enables switches far from each other to set up a stack. As shown in Figure 1-31, core switches in two cities set up a stack over a long-distance connection and work like one core device. In this way, the network structure is simplified, and the management and maintenance costs are reduced. In addition, each city is connected to the external network through two links, which greatly improves service reliability.
