This section describes stack application scenarios.

Increasing the Number of Ports

As shown in Figure 2-19, when the port density of a switch is insufficient for an increased number of users, you can connect another switch to the switch using stack cables. The two switches can set up a stack to provide more ports.

Figure 2-19 Increasing the number of ports

Increasing Bandwidth

As shown in Figure 2-20, you can use two switches to set up a stack and bundle physical links of the two switches into a link aggregation group to increase the uplink bandwidth.

Simplifying Network Topology

As shown in Figure 2-21, multiple switches are virtualized into a logical switch. This simplified network does not require MSTP or 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 2-22, aggregation switches on the two floors set up a stack over a long-distance connection and work like one aggregation device. In this way, the network structure is simplified, and the management and maintenance costs are reduced. In addition, each floor is connected to the core network through two links, which greatly improves service reliability.
