Service & Support: Software Center: Cisco IOS Software: Product Bulletins: Software
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.
Cisco IOS Release 12.2(2) XG supports the same feature sets as Cisco IOS Release 12.2, but Cisco IOS Release 12.2(2) XG can include new features supported by the Cisco 3600.
 |
Caution Cisco IOS images with strong encryption (including, but not limited to, 168-bit Triple Data Encryption Standard [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 because of United States government regulations. When applicable, purchaser and 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. |
Table 3, Table 4, and Table 5 list the features and feature sets supported by the Cisco 3600 series in Cisco IOS Release 12.1(5) YB4 and uses the following conventions:
|
Note This table might not be cumulative or list all the features in each image. You can find the most current Cisco IOS documentation on Cisco.com. These electronic documents may contain updates and modifications made after the hardcopy documents were printed. If you have a Cisco.com login account, you can find image and release information regarding features prior to Cisco IOS Release 12.1(5) YB by using the Feature Navigator tool at http://www.cisco.com/go/fn. |
The following is a list of the new hardware and software features supported by the Cisco 3600 series for Release 12.1(5)YB5.
There are no new hardware feature supported by Cisco IOS Release 12.1(5)YB4.
There are no new software feature supported by Cisco IOS Release 12.1(5)YB4.
There are no new hardware feature supported by Cisco IOS Release 12.1(5)YB2.
There are no new software feature supported by Cisco IOS Release 12.1(5)YB2.
The following new hardware feature is supported by the Cisco 2600 series for Cisco IOS Release 12.1(5)YB4.
The asymmetric digital subscriber line (ADSL) WAN interface card is a 1-port WAN interface card (WIC) for the Cisco 3600 series of modular access routers. The card provides asymmetric digital subscriber line (ADSL) high-speed digital data transfer between a single customer premises equipment (CPE) subscriber and the central office.
The ADSL WIC is compatible with the Alcatel Digital Subscriber Loop Access Multiplexer (DSLAM), the Cisco 6260 DSLAM with Flexi-line cards and the Cisco 6130 DSLAM with Flexi-line cards. It supports Asynchronous Transfer Mode (ATM) Adaptation Layer 5 (AAL5) and various classes of Quality of Service (QoS) for both voice and data service.
The following new software feature is supported by the Cisco 2600 series for Cisco IOS Release 12.1(5)YB4.
The ADSL Connectivity for Cisco 2600/3600 feature supports the 1-port ADSL wide-area network (WAN) interface card (WIC).
The PPP over Ethernet Client feature provides PPP over Ethernet (PPPoE) client support on routers on customer premises. Before the introduction of this feature, Cisco IOS software supported PPPoE on the access server side only.
The PPPoE Client feature provides PPPoE client support on ATM permanent virtual circuits (PVCs) and Ethernet interfaces. A dialer interface must be used for cloning virtual access.
One ATM PVC will support one PPPoE client. Multiple PPPoE clients can run concurrently on different PVCs, but each PPPoE client must use a separate dialer interface and a separate dialer pool.
Multiple PPPoE client sessions can be configured on an Ethernet interface, but each session must use a separate dialer interface and a separate dialer pool.
More information about this feature can be found at:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t2/ftpppoec.htm
A defect in multiple releases of Cisco IOS software will cause a Cisco router or switch to halt and reload if the Cisco 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 Cisco 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
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.
| Old Product Number | New Product Number | Release | Image Description |
|---|---|---|---|
Old Cisco Management Information Bases (MIBs) will be replaced in a future release. OLD-CISCO-* MIBS are currently migrated into more scalable MIBs—without affecting existing Cisco IOS products or network management system (NMS) applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 6.
| Deprecated MIB | Replacement |
|---|---|
Caveats describe unexpected behavior or defects 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 12.1(5)YB5, see this "Caveats" section as well as Caveats for Cisco IOS Release 12.1 and Caveats for Cisco IOS Release 12.1T . These documents list severity 1 and 2 caveats and select severity 3 caveats for Cisco IOS Releases 12.1 and 12.1T and are located on Cisco.com and the Documentation CD-ROM.
All caveats in Cisco IOS Release 12.1(5)T are also in Cisco IOS Release 12.1(5)YB5.

This section documents possible unexpected behavior by Cisco IOS Release 12.1(5)YB4 and describes only severity 1 and 2 caveats and select severity 3 caveats.
Some ports on the Digital T1 Packet voice Trunk modules don't come up when used with AAL2 ports.
This bug appeared very rarely and is now unreproducible.
There are no closed or resolved caveats for Cisco IOS Release 12.1(5)YB4.
This section documents possible unexpected behavior by Cisco IOS Release 12.1(5)YB2 and describes only severity 1 and 2 caveats and select severity 3 caveats.
There are different versions of ID PROMs for the WAN Interface Cards (WICs). Cisco IOS Release 12.1(5)YB and later releases recognize versions 0, 1 and 4. The T1 WIC has an ID PROM version 2. Release 12.1(5)YB and later releases are not able to recognize and read the EEPROM contents for the T1 WIC. The T1 WIC is recognized in the show run command, but not in the show diag command. There is no workaround.
There are no closed or resolved caveats for Cisco IOS Release 12.1(5)YB2.
There are no open caveats for Cisco IOS Release 12.1(5)YB.
Since Release 12.1(5)YB is the initial release, there are no closed or resolved caveats.
