RedundancyOn
RedundancyOn
(SmartSwitch 6500 Only)
Use RedundancyOn to activate support for automatic TSM/CPU redundancy. If automatic TSM/CPU redundancy is
activated, the TSM/CPU slave module monitors activity of the TSM/CPU master module. Every second, the master
module sends a heartbeat signal to the slave. If the slave does not receive five consecutive heartbeats, it assumes the
master is not active and reboots the switch. If the master still is not alive after reboot, automatic CPU switchover occurs
(the slave module becomes the master module and vice versa). During the period the slave module monitors the master
module, the configuration of the slave module is automatically kept current with configuration of the master module.
Note
To deactivate support for automatic TSM/CPU redundancy, use the
RedundancyOff attribute. If you choose to deactivate automatic TSM/CPU
redundancy, you can use manual TSM/CPU redundancy with the CPUswitchover,
RedundancyInfo, and RedundancyConfigBackup attributes.
