Switch Software Releases

Switch Software Releases
The switch software is regularly updated with new features and bug fixes, and you might want to upgrade
your Catalyst 2950 with the latest software release. New software releases are posted on Cisco.com on the
World Wide Web and are available through authorized resellers. Cisco also supplies a TFTP server that
you can download from Cisco.com.
Before upgrading a switch, first find out the software version that the switch is running. You can do this
by using the Software Upgrade window, by selecting Help > About, or by using the show version
privileged EXEC command.
