1 This feature is offered in the Basic feature set.
2 This feature is offered in the Plus feature set.
3 This feature is offered in the encryption feature sets which consist of 40-bit (Plus 40) data encryption feature sets.
4 This feature is offered in the encryption feature sets which consist of IPsec 56-bit (Plus IPsec 56) data encryption feature sets.
CautionCisco 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, the purchaser or user must obtain local import and use authorizations for all encryption strengths. Contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.
Table 4, Part 1 and Table 4, Part 2, list the features and feature sets supported by Cisco IOS Release 12.0(15) for the Cisco 2600 Series. Both tables use the following conventions to identify features:
•
Yes—The feature is supported in the feature set.
•
No—The feature is not supported in the feature set.
Note
This feature set table contains only a selected list of features. This table is not a cumulative or complete list of all the features in each image.
New and Changed Information
The following sections list the new hardware and software features supported by the Cisco 2600 series for Release 12.0(15).
New Hardware Features in Release 12.0(15)
There are no new hardware features supported by the Cisco 2600 series in Cisco IOS Release 12.0(15).
New Software Features in Release 12.0(15)
There are no new software features supported by the Cisco 2600 series in Cisco IOS Release 12.0(15).
Limitations and Restrictions
MIBs
Old Cisco Management Information Bases (MIBs) will be replaced in a future release. Currently, OLD-CISCO-* MIBs are being converted into more scalable MIBs—without affecting existing Cisco IOS products or NMS applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 5.
Important Notes
Caveat CSCdr91706 and IOS HTTP Vulnerability
A defect in multiple releases of Cisco IOS software will cause a Cisco router or switch to halt and reload if the IOS HTTP service is enabled, browsing to http://router-ip/anytext?/ is attempted, and the enable password is supplied when requested. This defect can be exploited to produce a denial of service (DoS) attack.
The vulnerability, identified as Cisco bug ID CSCdr91706, affects virtually all mainstream Cisco routers and switches running Cisco IOS software releases 12.0 through 12.1, inclusive. This is not the same defect as CSCdr36952.
The vulnerability has been corrected and Cisco is making fixed releases available for free to replace all affected IOS releases. Customers are urged to upgrade to releases that are not vulnerable to this defect as shown in detail below.
This vulnerability can only be exploited if the enable password is known or not set.
You are strongly encouraged to read the complete advisory, which is available at
http://www.cisco.com/warp/public/707/ioshttpserverquery-pub.shtml.
Product Number Change
Beginning with Cisco IOS Release 12.0(7)XK, Cisco changed the product numbers you use to order a specific Cisco IOS software image. In short, Cisco will remove the periods separating the release train, maintenance release, and build number. The following table provides some examples.
Caveats
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only select severity 3 caveats are included in the caveats document.
For information on caveats in Cisco IOS Release 12.0(15), see Caveats for Cisco IOS Release 12.0 that lists severity 1 and 2 caveats and select severity 3 caveats for Release 12.0 and is located on CCO and the Documentation CD-ROM.
