Chapter 7 Configure Switch Features
You can configure redundant gateways on switches that are either ring
supervisors or ring nodes.
Figure 16 shows two Stratix 5700 switches that are configured as ring
supervisors with redundant gateway:
• One switch is configured as the active ring supervisor and also the active
redundant gateway.
• The other switch is configured as a backup ring supervisor and the
backup redundant gateway.
In this example, the switch acts as a ring supervisor. The switch also manages
redundant gateway switchovers.
