 |
Note Use these release notes with the information in the Cisco IOS Release 12.1(14)EA1 release notes for these specific switch platforms. |
|
Note Cisco IOS Release 12.1(14)EA1a is compatible with Catalyst 3750 switch stacks containing stack members running Cisco IOS Release 12.1(14)EA1. We recommend upgrading the entire switch stack to Cisco IOS Release 12.1(14)EA1a if at least one stack member is running this release. |
These release notes include important information about this release and any caveats that apply to it. See the "Related Documentation" section for links to the switch documentation on Cisco.com.
This document has the following sections:
The switches can now authenticate 802.1X clients running the Open 1x supplicant on Linux or the Meetinghouse supplicant on the MacOS.
Jumbo frames, when enabled by using the system mtu jumbo size global configuration command, no longer halt the switch CPU.
The switch no longer drops small IP packets (less than 46 bytes in size, including the IP header and payload) that are routed through Cisco Express Forwarding (CEF).
Virtual Terminal Protocol (VTP) pruning works properly even when the switch stack is the Spanning Tree Protocol (STP) root.
After the switch stack reloads, VLAN access control list (ACL) configurations are retained on the correct VLANs.
New software releases are posted on Cisco.com and are also available through authorized resellers. These tables list the software filenames for this software release:

Note We recommend that you download the combined .tar file that contains the image file and the HTML files. For instructions on how to upgrade your switch, refer to the Cisco IOS Release 12.1(14)EA1 release notes for your switch platform. |

Caution The Catalyst 3550, 2955, 2950, and 2950LRE crypto images include a bootloader upgrade. The bootloader can take up to 30 seconds to upgrade. Do not power cycle the switch while you are copying this image to the switch. If a power failure occurs when you are copying this image to the switch, call Cisco Systems immediately. |

Cisco provides Cisco.com, which includes the Cisco Technical Assistance Center (TAC) website, as a starting point for all technical assistance. Customers and partners can obtain online documentation, troubleshooting tips, and sample configurations from the Cisco TAC website. Cisco.com registered users have complete access to the technical support resources on the Cisco TAC website, including TAC tools and utilities.
Cisco.com offers a suite of interactive, networked services that let you access Cisco information, networking solutions, services, programs, and resources at any time, from anywhere in the world.
Cisco.com provides a broad range of features and services to help you with these tasks:
To obtain customized information and service, you can self-register on Cisco.com at this URL:

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The type of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.
We categorize Cisco TAC inquiries according to urgency:
The Cisco TAC website provides online documents and tools to help troubleshoot and resolve technical issues with Cisco products and technologies. To access the Cisco TAC website, go to this URL:
All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website require a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:
http://tools.cisco.com/RPF/register/register.do
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC website, you can open a case online at this URL:
http://www.cisco.com/tac/caseopen
If you have Internet access, we recommend that you open P3 and P4 cases online so that you can fully describe the situation and attach any necessary files.
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:

Before calling, please check with your network operations center to determine the Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the center, please have available your service agreement number and your product serial number.
Information about Cisco products, technologies, and network solutions is available from various online and printed sources.
