To increase availability, the SSO capability is enabled by default when Cisco Catalyst 9300 Series Switches are deployed in StackWise-480/320 mode. No additional user intervention is required to enable the SSO capability on a Cisco Catalyst 9300 Series system. The user can verify that SSO is configured and that the operational state is using a consistent CLI as a modular Cisco Catalyst system. The following example shows the sample output of SSO redundancy in the StackWise-480/320 based network design.
