Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay due to United States government regulations. When applicable, purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com. |

The following is a list of the new hardware and software features supported by Cisco 4000 series routers for Release 12.1.
There are no new hardware features supported by the Cisco 4000 series in Release 12.1(4).
There is one new software image supported for the Cisco 4000 series in Release 12.1(4). The new IP/SNASw Plus image (c4500-a3is-mz) allows a non-Enterprise SNA Switch image to run on the Cisco 4500-M platform with 32 MB RAM.
Old Cisco Management Information Bases (MIBs) will be replaced in a future release. OLD-CISCO-* MIBs are currently migrated into more scalable MIBswithout affecting existing Cisco IOS products or NMS applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 8.
