APPENDIX
A
Recommendations for Upgrading a
Catalyst 2950 Switch to a Catalyst 2960 Switch
This appendix describes the configuration compatibility issues and the feature behavior differences that
you might encounter when you upgrade a Catalyst 2950 switch to a Catalyst 2960 switch.
This appendix consists of these sections:
• Configuration Compatibility Issues, page A-1
• Feature Behavior Incompatibilities, page A-5
Configuration Compatibility Issues
The configuration commands between the two switch platforms differ for these reasons:
• The Catalyst 2950 switch runs Cisco IOS 12.1EA software, and the Catalyst 2960 switch runs Cisco
IOS 12.2SE software.
• The switch families have different hardware.
If you use a Catalyst 2950 switch command, it might not be supported on the Catalyst 2960 switch. The
Catalyst 2960 switch software handles the incompatible commands in these ways:
• They are accepted and translated. A message appears.
• They are rejected. A message appears.
In most cases, configuration files are loaded without rejections. Table A-1 lists the Catalyst 2950
exceptions. The features are listed in alphabetic order, with Catalyst 2950 commands and explanations,
and the resulting action on the Catalyst 2960 switch.
