CSS
Context
A cluster switch system (CSS) connects two physical switches using dedicated CSS cables into a single logical switch. A CSS is also called a cluster. A single switch cannot meet requirements of increasing data access in data centers and high network reliability, while CSS can provide high forwarding performance and high network reliability. After two switches set up a CSS, one switch functions as the master switch, and the other functions as the backup switch.
The S7703 and S7703 PoE do not support this function.
In CSS card clustering, CSS ports cannot be configured.
Procedure
- Choose in the navigation tree to open the CSS page, as shown in Figure 5-140.
- Set CSS status to ON and CSS mode to CSS card clustering or Service port clustering.
- Click the data line below Configure CSS Members to configure Master switch or Standby switch, as shown in Figure 5-141. Set parameters and click
