The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.

Information About System-Level High Availability
Configuring System-Level High Availability
The High Availability feature can be enabled on a previously deployed standalone InterCloud Link. In doing so, the previously standalone InterCloud Link is given the HA role primary and remains active after the feature is enabled. A standby InterCloud Link is created and paired with the existing InterCloud Link.
Caution |
HA to standalone deployment mode change is not supported in this release. |
Use one of the following commands to display High Availability related information or perform a switchover:
Command |

The Redundancy Manager event-logs can be configured using the following command:
Command |
Source |
Purpose |
---|---|---|
[ no ] event-log redundancy-mgr { trace | info | error } [ terminal ] |
InterCloud Switch InterCloud Extender |
Configures the Redundancy Manager event logs. |
There are three levels of event-logs: Trace, Info, and Error (most critical). Info and Error event logs are enabled by default.
The optional parameter terminal will display the event-logs in real time on the terminal.
