Application Scenarios for CSS

Application Scenarios for CSS

Bandwidth Expansion and Inter-Chassis Link Redundancy

When higher uplink bandwidth is required for a switch if the network size increases, a new switch can be added to that switch to set up a CSS. In addition, multiple physical links of the two member switches can bundle into a link aggregation group to increase the uplink bandwidth of the switch, as shown in Figure 3-22.

Downstream switches connect to the CSS through inter-chassis Eth-Trunks. This networking implements redundancy between devices and links, enhancing network reliability.

Simplified Network Topology

In Figure 3-23, two switches set up a CSS and are virtualized into a single 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-chassis link aggregation also speeds up network convergence and improves network reliability.

Long-Distance Clustering

Long-distance clustering enables switches far from each other to set up a CSS. In Figure 3-24, users on each floor of two buildings connect to the aggregation switches through their respective corridor switches. The aggregation switches connect users to the external network. The aggregation switches in the two buildings can be connected using cluster cables to set up a CSS. The two aggregation switches then work as if they were one aggregation switch, simplifying the network structure and reducing the device management and maintenance costs. In addition, two links to the external network are available to users in each building, which greatly improves service reliability.
