The redundancy force-switchover command first verifies that the redundant supervisor engine is in the correct state. Because all the interfaces are configured only on the Active box, but are synchronized with the Standby box, the same set of interfaces are configured on both controller s. Due to the software version mismatch between the two chassis, the VSS standby chassis will be in RPR redundancy mode. 4510#sh redundancy. Using “send break” to break or pause the system is not recommended and may cause unpredictable results. Consider the scenario of an HA cluster with two nodes, Node A and Node B. I was under the impression that when I forced a switch to the standby sup using the redundancy force-switchover that it would be seamless.
