This test is to verify how long SSO and NSF takes to recover. SSO without NSF Issue redundancy force-switchover command from privilege exec mode. This command forces primary RSP to reboot so that secondary RSP takes over as primary. The time for secondary RSP to take over as primary is 3 second, if no NSF … Continue reading Stateful switch over and non-stop forwarding test
