For Catalyst 4500 switches running EnergyWise Phase 2 and later:

For high availability

To perform an ISSU downgrade from a Cisco IOS release supporting EnergyWise Phase 2 to an earlier software release that does not support EnergyWise, disable EnergyWise on the switch first.

To perform an ISSU downgrade from a software release supporting EnergyWise Phase 2 to a release supporting EnergyWise Phase 1, disable EnergyWise on the switch first because of CLI compatibility issues between EnergyWise Phase 1 and EnergyWise Phase 2.

To perform an ISSU downgrade from a Cisco IOS release supporting EnergyWise Phase 2 to an earlier release that does not support EnergyWise, you must remove the snmp-server enable traps energywise global configuration command from the switch configuration.

During an ISSU upgrade from a software release supporting EnergyWise Phase 1 to a release supporting EnergyWise Phase 2, the EnergyWise settings in the running configuration are updated. The switch sets the management password to the same domain password as in the energywise domain command. You must enter the copy running-config startup-config privileged EXEC command to save the EnergyWise settings in the configuration file.

For stateful switchover (SSO) mode

On a redundant chassis operating in SSO mode, the energywise neighbor hostname udp-port-number global configuration command does not work. Use the energywise neighbor ip-address udp-port-number global configuration command to specify the IP address of the host.


Note If your switch is running EnergyWise Phase 2, enter the no energywise domain global configuration command to disable EnergyWise before downgrading your software to a release supporting EnergyWise Phase 1.
