Release Notes for the Catalyst 3750 Switch
Cisco IOS Release 12.1(14)EA1
July 2003
The Cisco IOS Release 12.1(14)EA1 runs on all Catalyst 3750 switches. Catalyst 3750 switches support
stacking through Cisco StackWise technology. Unless otherwise noted, the term switch refers to a
standalone switch and to a switch stack.
These release notes include important information about this Cisco IOS release and any limitations,
restrictions, and caveats that apply to it. Verify that these release notes are correct for your switch:
If you are installing a new switch, refer to the Cisco IOS release label on the rear panel of your
switch.
If your switch is on, use the show version privileged EXEC command. See the “Determining the
Software Version and Feature Set” section on page 4.
If you are upgrading to a new release, refer to the software upgrade filename for the software
version.
For the complete list of Catalyst 3750 switch documentation, see the “Related Documentation” section
on page 30.
You can download the switch software from these sites:
http://www.cisco.com/kobayashi/sw-center/sw-lan.shtml
(for registered Cisco.com users with a login password)
http://www.cisco.com/public/sw-center/sw-lan.shtml
(for nonregistered Cisco.com users)
This software release is part of a special release of Cisco IOS software that is not released on the same
8-week maintenance cycle that is used for other platforms. As maintenance releases and future software
releases become available, they will be posted to Cisco.com (previously Cisco Connection Online
[CCO]) in the Cisco IOS software area.
Note If you are upgrading a switch that uses the 802.1X feature, you must re-enable 802.1X after upgrading
the software. For more information, see the “Cisco IOS Notes” section on page 20.
