Release Notes for Cisco 7200 Series for Cisco IOS Release 12.0 XK
February 12, 2002
Note
You can find the most current Cisco IOS documentation on Cisco Connection Online (CCO). These electronic documents may contain updates and modifications made after the hardcopy documents were printed.
These release notes for the Cisco 7000 family of routers support Cisco IOS Release 12.0(7)XK3. These release notes describe new features, memory requirements, hardware support, and changes to the microcode or modem code and related documents.
For a list of the software caveats that apply to Release 12.0(7)XK3, see the "Caveats" section, the Caveats for Cisco IOS Release 12.0 T document, and the Caveats for Cisco IOS Release 12.0 document that accompany these release notes. All caveats in Release 12.0 and Release 12.0 T are also in Release 12.0 XK. The caveats documents are updated for every maintenance release and are located on Cisco Connection Online (CCO) and the Documentation CD-ROM.
Use these release notes with the Cross-Platform Release Notes for Cisco IOS Release 12.0 and the Release Notes for Cisco 7000 Family for Cisco IOS Release 12.0 T located on CCO and the Documentation CD-ROM.

New Software Features in Cisco IOS Release 12.0(7)XK
The following new software feature is supported by the Cisco 7200 for Release 12.0(7)XK:
QSIG for Cisco 7200 Series Routers
QSIG protocol support allows Cisco voice switching services to connect private branch exchanges (PBXs), key systems (KTs), and central office switches that communicate by using the QSIG protocol, which is becoming the standard for PBX interoperability in Europe and North America. With QSIG, Cisco networks emulate the functionality of the PSTN, and QSIG signaling messages allow the dynamic establishment of voice and data connections across a Cisco wide-area network (WAN) to a peer router, which can then transport the signaling and voice packets to a second PINX.
The Cisco voice packet network appears to the traditional QSIG PBXs as a distributed transit PBX that can establish calls to any PBX, non-QSIG PBX, or other telephony endpoint served by a Cisco gateway, including non-QSIG endpoints. When originating and terminating on QSIG endpoints, the QSIG messages are passed transparently across the network; the PBXs are responsible for processing and provisioning the supplementary services. When linking QSIG and non-QSIG endpoints served by a Cisco packet voice gateway, only basic calls are supported. In addition, all switched voice connections must be established and torn down in response to QSIG control messages.
QSIG support includes the following capabilities:
•
•
•
•
MIBs
Current MIBs
If you have an account with CCO, you can find the current list of MIBs supported by Cisco. To reach the Cisco Network Management Toolkit, log in to CCO and click Software Center: Network Mgmt Products: Cisco Network Management Toolkit: Cisco MIBs.
Deprecated and Replacement 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
The following sections contain important notes about Cisco IOS Release 12.0(7)XK3 that can apply to the Cisco 7200 series routers.
Image Obsolescence
All Cisco 7200 series images in Cisco IOS Release 12.0(7)XK1 have been obsoleted from manufacturing.
These images are now available in Cisco IOS Release 12.0(7)XK2 and Cisco IOS Release 12.0(7)XK3.
Note
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 Cisco IOS Release 12.1(3a)E4 or later releases of Cisco IOS Release 12.1 E.
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 .
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.
This section only contains open and resolved caveats for the current Cisco IOS maintenance release. only.
All caveats in Cisco IOS Release 12.0 and Release 12.0 T are also in Release 12.0 XK3.
For information on caveats in Cisco IOS Release 12.0, see Caveats for Cisco IOS Release 12.0 document on CCO and the Documentation CD-ROM.
For information on caveats in Cisco IOS Release 12.0 T, see the Caveats for Cisco IOS Release 12.0 T, which lists serverity 1 and 2 caveats and select severity 3 caveats and is located on CCO and the Documentation CD-ROM.
Note
Open for Caveats for Release12.0(7)XK3
There are no open caveats specific to Cisco IOS Release 12.0(7) XK3 that require documentation in the release notes.
Resolved Caveats for Release12.0(7)XK3
All the caveats listed in this section are resolved in Cisco IOS Release 12.0(7) XK3. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
