In role switching, the mirror server acts as the failover partner for the principal server, taking over the principal role, recovering its copy of the database. Redundant System Information :-----Available system uptime = 7 weeks, 3 days, 13 hours, 20 minutes. 553: %SYS-5-SWITCHOVER: Switchover requested by Exec. There are two options for Cisco Wireless Controller redundancy solutions, either Backup Controllers or High Availability, depending on the firmware version of WLC's, failover time requirement, and budget. This command will trigger a manual switchover where the Active WLC will reboot and the Standby WLC will take over the network. Hope it Helps. If you issue the reload command and the status is not standby hot or standby cold, the reload command will reset the current supervisor engine and the peer supervisor may not be able to take over because it was not in a. 30 in our case) and type in the following command: redundancy force-switchover. Device# redundancy force-switchover Stack is in Half ring setup; Reloading a switch might cause stack split This will reload the active unit and force switchover to standby[confirm] Examples. Switchovers system experienced = 4. Failover gives you the ability to continue to run the thin client by connecting to a backup. Cisco 7600 series routers support these redundancy modes: RPR—Supports a switchover time of 2 or more minutes. Conducts a manual switchover to the redundant supervisor engine. Redundancy-MGNT: 192. Router# show redundancy Redundant System Information : ----- Available system uptime = 31 minutes Switchovers system experienced = 1 Standby failures = 0 Last switchover reason = user forced Hardware Mode = Simplex Configured Redundancy Mode = sso Operating Redundancy Mode = Non-redundant Maintenance Mode =. PE node redundancy for Virtual Private Wire Service (VPWS), Virtual Private LAN Service (VPLS), and native Ethernet aggregation. There are two versions to this: 1. ". Configures RPR. Failover: The term for when services on one node "fail over" to another node in the event of an emergency, or when manually moved. exitRedundancy Force-Switchover. Reason: Stateful Switchover. Thus, when a system failure occurs, there is another system that serves as a backup. Further to the good information by Paul, the failover duration depends on the supervisor and the mode of redundancy that has been configured, it cannot be predetermined:-. 150. Uplinks and access ports on other switches will remain online. To force a switchover use the command: redundancy force-switchover. The Layer-3 redundancy role is driven by user configuration at both the primary and secondary Mobility Master. " This section explains the basics of these two concepts. Clustered : a group of computers provide a service in a way that looks to the client like a single computer.
