Using Cisco EnergyWise and Catalyst 4500 Switches


Catalyst 4500 switches support the Cisco EnergyWise features and functionality as previously described in this guide. This appendix describes any Catalyst 4500 switch-specific EnergyWise functions.

Catalyst 4500 switches running Cisco EnergyWise Version 2.6 and later:

High availability

To perform an ISSU downgrade from a Cisco IOS release supporting Cisco EnergyWise Version 2.6 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 Cisco EnergyWise Version 2.6 to a release supporting EnergyWise Version 1, disable EnergyWise on the switch first because of CLI compatibility issues between EnergyWise Version 1 and EnergyWise Version 2.6.

To perform an ISSU downgrade from a Cisco IOS release supporting Cisco EnergyWise Version 2.6 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 Cisco EnergyWise Version 1 to a release supporting Cisco EnergyWise Version 2.6, 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.

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 domain member is running Cisco EnergyWise Version 2.6 or later and you need to downgrade to Cisco EnergyWise Version 1.0 due to domain member compatibility issues, enter the no energywise domain global configuration command to disable EnergyWise before downgrading your software to a release supporting EnergyWise Version 1.
