Upgrading to a New Software Release

For general information about upgrading to a new software release, refer to Software Installation and Upgrade Procedures located at the following URL:

http://www.cisco.com/warp/public/130/upgrade_index.shtml

Feature Set Tables

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)XA4 supports the same feature sets as Cisco IOS Release 12.2, but Cisco IOS Release 12.2(2)XA4can include new features supported by the Cisco 7000 Family.


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 2 lists the features and feature sets supported by the Cisco 7000 family in Cisco IOS Release 12.2(2)XA4 and uses the following conventions:

Yes—The feature is supported in the software image.

No—The feature is not supported in the software image.

In—The number in the "In" column indicates the Cisco IOS release in which the feature was introduced. For example, (1) means a feature was introduced in 12.2(1)MB.


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 hard-copy documents were printed.

New Software Features in Cisco IOS Release 12.2(2)XA

The following new software features are supported by the Cisco 7000 family for Cisco IOS Release 12.2(2)XA:

Cisco H.323 Scalability and Interoperability Enhancements

Platforms: Cisco 7200 series routers

The Cisco H.323 Scalability and Interoperability Enhancements feature upgrades the Cisco H.323 Gatekeeper (GK) and Cisco H.323 Gateway to comply with H.323 Version 3. The enhancements include:

Support for mandatory H.323 Version 3 elements in the gateway and GK, including:

multipleCalls—This field is set to TRUE in all H.225 messages for TCP calls.

maintainConnection— If the call-idle timer is set to a nonzero value, this field is set to TRUE in all H.225 messages for TCP calls. Otherwise, it is set to FALSE.

alternateTransportAddresses—This structure contains the keyword annexE and the transport address of an alternate Annex E.

useSpecifiedTransport—This field is marked as annexE. It is accompanied by the alternateTransportAddresses

structure which specifies the Annex E transport address.

Support for H.225 call signalling over UDP. H.225 messages can be transported over TCP or UDP (as described in Annex E). At registration time, a Cisco H.323 Gateway indicates to the GK whether it is capable of transmitting over both TCP and UDP. If it is, the Cisco H.323 Gateway registers both its TCP and UDP addresses.

Address resolution using border elements (BE). The BE (as described in Annex G) is colocated with the Cisco H.323 Gatekeeper and provides additional address resolution capabilities. The BE can cache address information from neighboring BEs. When the GK receives a call that it cannot resolve, it can contact its local BE. If the address is in the BE's cache, the BE on the GK sends an AccessRequest to the BE in the terminating domain. If the address is not in the BE's cache, then the BE attempts to resolve the address by sending an AccessRequest to each of its neighboring BEs.

Support for bandwidth request (BRQ) messages. The Cisco H.323 Gateway requests the maximum bandwidth required to establish a call when it requests call admission using the admission request (ARQ) message. If the Codec type used for the established call requires less bandwidth than that allocated, the Cisco H.323 Gateway reports the lesser amount using the BRQ message. This BRQ message reports the actual bandwidth being utilized by the call. The bandwidth reported in the BRQ overrides the value previously reported in the ARQ message.

Support for concurrent calls over a single H.225 call signalling channel. The call signalling channel is capable of carrying signalling for many concurrent calls. It uses the call reference value to associate a message with the call. H.323 endpoints indicate whether they are capable of handling multiple calls by setting a flag in the H.225 messages. If endpoint is unable to process any new calls on a given TCP connection, it can request a new connection by rejecting the SETUP message with a ReleaseComplete message with the cause code set to NewConnectionNeeded. The originating endpoint then establishes a new TCP connection and continues with the call setup. Cisco gateways have been enhanced to establish a new connection if a third-party endpoint requests one.

Important Notes

Image Obsolescence, Cisco IOS Release 12.2(2)XA

All Cisco 7200 series images in Cisco IOS Releases 12.2(2)XA have been obsoleted from manufacturing.

These images are now available in Cisco IOS Release 12.2(2)XA1.


Note Disclaimer: In order to increase network availability, Cisco recommends that you upgrade affected IOS images with the suggested replacement software images. Cisco will discontinue manufacturing shipment of affected IOS images. Any pending order will be substituted by the replacement software images. PLEASE BE AWARE THAT FAILURE TO UPGRADE THE AFFECTED IOS IMAGES MAY RESULT IN NETWORK DOWNTIME. The terms and conditions that governed your rights and obligations and those of Cisco, with respect to the deferred images, will apply to the replacement images.


Caveats for Cisco IOS Release 12.2 XA

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 contains only open and resolved caveats for the current Cisco IOS maintenance release.

All caveats in Cisco IOS Release 12.2 and Cisco IOS Release 12.2 T are also in Cisco IOS Release 12.2(2)XA4.

For information on caveats in Cisco IOS Release 12.2, see Caveats for Cisco IOS Release 12.2.

For information on caveats in Cisco IOS Release 12.2 T, see Caveats for Cisco IOS Release 12.2 T, which lists severity 1 and 2 caveats and select severity 3 caveats and is located on Cisco.com and the Documentation CD-ROM.


Note If you have an account with Cisco.com, you can use Bug Navigator II to find caveats of any severity for any release. To reach Bug Navigator II, log in to Cisco.com and click Software Center: Cisco IOS Software: Bug Toolkit: Bug Navigator II. Another option is to go to http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl. 


Because Cisco IOS Release 12.2(2)XA is the initial base release, there are no resolved caveats. For a list of the resolved caveats, refer to the next set of release notes for this release version.

Resolved Caveats—Release 12.2(2)XA5

All caveats in this section have been resolved in Cisco IOS Release 12.2(2)XA5 but may be open in previous Cisco IOS releases.

CSCdw65903

An error can occur with management protocol processing. Please use the following URL for further information:

http://www.cisco.com/cgi-bin/bugtool/onebug.pl?bugid=CSCdw65903

Open Caveats—Cisco IOS Release 12.2(2)XA4

This section documents possible unexpected behavior by Cisco IOS Release 12.2(2)XA4 and describes only severity 1 and 2 caveats and select severity 3 caveats.

There are no open caveats for Cisco IOS Release 12.2(2)XA4.

Resolved Caveats—Cisco IOS Release 12.2(2)XA4

All the caveats listed in this section are resolved in Cisco IOS Release 12.2(2)XA4. This section describes only severity 1 and 2 caveats and select severity 3 caveats.

There are no resolved caveats for Cisco IOS Release 12.2(2)XA4.

Open Caveats—Cisco IOS Release 12.2(2)XA1

This section documents possible unexpected behavior by Cisco IOS Release 12.2(2)XA1 and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdt87418

Call redirection on a Cisco IOS voice gateway may fail when "huntstop" is configured on the incoming Voice over IP (VoIP) dial-peer.

Workaround: Remove the huntstop configuration from the incoming VoIP dial-peer.

CSCdu52821

A Cisco 7200 router with PA-VXC-2TE1+ may, under heavy stress, experience Digital Signal Processor (DSP) timeouts follow by a router reload due to a Watchdog Hard Reset.

There are no known workarounds.

CSCdu78226

On a Cisco 7200 series router, calls may fail several hours into a load run and the following message is shown on the console:

%VTSP-3-DSP_TIMEOUT: DSP timeout on event 0x6:

One or more Digital Signal Processors (DSP) may be shown as not responding.

Workaround: Reset the DSP.

Alternative Workaround: Invoke shut/noshut on the voice port when the problem occurs.

Resolved Caveats—Cisco IOS Release 12.2(2)XA1

All the caveats listed in this section are resolved in Cisco IOS Release 12.2(2)XA1. This section describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCds24111

On a Cisco7200 series router, the ATM sub-interface can be entered without specifiying link type. It is a parser related issue and once the subinterface is created it doesn't show up in the config.

Cache entries are not formed properly for the commands that use TEST macros like IFELSE, ASSERT, etc.

Workaround: Disable the prser cache using the no parser cache config command.

CSCdt59455

A Cisco router executing the vty-async virtual-template <n> command may have the Point-to-Point Protocol (PPP) connection abruptly terminated if the "virtual-template <n>" interface has "no peer default ip address".

Workaround: Configure "peer default ip address pool WORKAROUND" and then "ip local pool WORKAROUND a.b.c.d" where a.b.c.d is an IP address.

CSCdt93862

When HTTP server is enabled and local authorization is used, it is possible, under some circumstances, to bypass the authentication and execute any command on the device. It that case, the user will be able to exercise complete control over the device. All commands will be executed with the highest privilege (level 15).

All releases of Cisco IOS® software, starting with the release 11.3 and later, are vulnerable. Virtually, all mainstream Cisco routers and switches running Cisco IOS are affected by this vulnerability.

Products that are not running Cisco IOS software are not vulnerable.

The workaround for this vulnerability is to disable HTTP server on the router or to use Terminal Access Controller Access Control System (TACACS+) or Radius for authentication.

This advisory will be posted at http://www.cisco.com/warp/public/707/IOS-httplevel-pub.html 

CSCdu04236

A Cisco 7200 series router running Cisco IOS Release 12.2(1c) and voice features may crash with the following message:

System was restarted by error - a Software forced crash, PC 0x60437124 at 17:43:43 UTC 
Thu Aug 23 2001

There are no known workarounds.

CSCdu07504

A Cisco router that is running Cisco IOS Release 12.1(5)XM2 may experience a software-forced reload when the show voice dsp EXEC command is entered. The following message is displayed when the show version EXEC command is entered:

mc3810-sm-ish02 uptime is 10 minutes System returned to ROM by error - software forced crash, PC 0x2242AC System image file is "flash:mc3810-a2jsv5-mz.121-5.xm2"

There are no known workarounds.

CSCdu08214

A Cisco router using the CallTracker Management Information Base (MIB) to poll for the userid of active users will have NULL return when Calling Line Identification (CLID) and Digital Number Identification Service (DNIS) information is not available.

There are no known workarounds.

CSCdu30105

A Cisco 7200 series router running Cisco IOS Release 12.1(7.3)E or 12.2(1.3) may experience a reload when a vendor-specific challenge handshake authentication protocol authentication is performed through a RADIUS server when the wrong username or password is entered and when the RADIUS server returns an access-reject with at least one attribute other than the vendor-specific attribute (VSA).

There are no known workarounds.

CSCdu46942

A Cisco router with Interactive Voice Response (IVR) scripts playing a "Number Unobtainable" (NU) tone will result in a dial tone. If cptone is set to GB, then there will be silence (no tone).

There are no known workarounds.

CSCdu56186

On a Cisco router, a Resource Reservation Protocol (RSVP) and signal-only call is cleared by a terminating gateway after the gateway receives a Admission Confirm (ACF) message from the gatekeeper. This is the same problem as that reported with CSCdt66034. The fix for CSCdt66034 does not include the gatekeeper configuration case.

There are no workarounds.

CSCdu57066

A Cisco router with voice ports can get stuck in the S_PROCEEDING state because the CCH323_H225_EVENT_CONN_LOST event is not handled in the CCH323_H225_STATE_ACC_FASTSTART_PROGRESS state.

There are no known workarounds.

CSCdu59975

On a Cisco router, a glare condition may occur randomly on all voice platforms in Cisco IOS Release 12.2(1a), 12.2(2)T, or 12.2 XA when a busy port is assigned to a new incoming call. A glare condition occurs when two calls are assigned to the same port. For example, if there are only two ports, and they are both busy on a call when a new call comes in without a check for glare, one of the busy ports is allocated to the new call. This condition causes the preexisting call to be disconnected and the new call to receive a busy signal.

There are no known workarounds.

CSCdu62721

On a Cisco router, incoming calls may fail to connect and may be released. The system does not put B channels on the first E1/T1 in service. Incoming calls are failing with channel unavailable. If the channels are "busyout" and "unbusy" the service is restored and calls can be properly accepted. This is observed on Cisco 5300 and 5800 universal access servers.

There are no known workaround.

CSCdu63369

On a Cisco router, traceback messages may be observed on the Cisco Router console during call disconnect. This does not affect any functionality.

There are no known workarounds.

CSCdu70661

On the Cisco AS5800 running IOS version 12.1(5)XM4, after provisioning the AS5800 to use SS7 Interconnect for Voice Gateways services for the first time, all the channels except for the 24th channel of the primary NFAS span may be stuck in channel service state = outofservice.

Workaround: Reload the box or perform a shut/no shut on the T3 controller or the individual T1 controllers.

CSCdu82224

A Cisco router sending a V.120 64Kbps call may have the call be mis-identified as a Personal Handy Phone System (PIAFS) call by the Cisco Universal Access Server AS5300/AS5400/AS5800/AS5850. This occurs if the Termainal Adaptor sent a Q.931 SETUP frame matching the following criterias:

1. The Low Layer Compatibility fields were present in SETUP frame.

2. The Octet 5 identify this was a V.120 call and Octet 5A user rate was 64Kbps or 32Kbps.

Workaround: Configure the Terminal Adaptor not to send any Lower Layer Compatibility fields for V.120 calls and use the autodetect encapsulation ppp v120 command at the D-channel configuration.

CSCdu87080

A Cisco router using a Trunking Gateway Control Protocol (TGCP) endpoint name with a domain name attached, such as ds/s-0/ds1-1/1@testnet.com, will have the endpoint name parsing fail and the message rejected with 500 error code.

Workaround: Use the local name for TGCP endpoints (ds/s-0/ds1-1/1) only.

CSCuk21553

A Cisco router performing the telnet command with the /ipv6 and /ipv4 flags may not function properly. With or without these flags, telnet fails to perform a DNS lookup of the target hostname.

However, if some application other than telnet should first perform the DNS lookup so that the host of interest is in the cache, then telnet will be able to contact the host by name.

Workaround: Specify the telnet server by IP address rather than by hostname.

Alternative workaround: Use the ip host command to enter the name->address mapping locally.

CSCuk23244

On a Cisco router, configuring a Primary Rate Interface (PRI) controller for an Integrated Services Digital Network (ISDN) using the pri-group command may cause an ISDN layer 2 failure.

Workaround: Save the ISDN configuration and reload the router.

Alternative workaround: Perform a shut command followed by a no shut command on the PRI controller.

Resolved Caveats—Cisco IOS Release 12.2(2)XA

All the caveats listed in this section are resolved in Cisco IOS Release 12.2(2)XA. This section describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdr56330

On a Cisco router with Gatekeeper running Cisco IOS Release 12.1(1)T, when the Gatekeeper has endpoint registrations with E.164 numbers, new "zone prefix" entries cannot be added to the Gatekeeper routing table.

Workaround: Shutdown the Gatekeeper before adding new "zone prefix" entries.

CSCdt30211

On a Cisco Route Switch Processor (RSP) that is running Cisco IOS Release 12.1, using the no encapsulation smds interface configuration command on a serial interface may cause the Ethernet interface on a connected router to go down.

There are no known workarounds.
