Upgrading to a New Software Release

For general information about upgrading to a new software release, see Software Installation and Upgrade Procedures located at: http://www.cisco.com/warp/public/130/upgrade_index.shtml.

Feature Sets

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. Release 12.2(2)XT supports the same feature sets as Releases 12.2 and 12.2 T, but Release 12.2(2)XT includes new features supported by the Cisco 1700 series routers.


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 can be denied or subject to delay due to United States government regulations. When applicable, the 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.

Table 2 (Parts 1 and 2) lists the features and feature sets supported by the Cisco 1700 series routers in Cisco IOS Release 12.2(2)XT. The table 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, "12.2(2)XT" means the feature was introduced in 12.2(2)XT. If a cell in this column is empty, the feature was included in the initial base release.


Note These feature set tables only contain a selected list of features. These tables are not cumulative—nor do they list all the features in each image. Additional features are listed in the Cross-Platform Release Notes for Cisco IOS  Release 12.2 T  and Release 12.2 T Cisco IOS documentation.

No new hardware and software features are supported by the Cisco 1700 series for Cisco IOS Release 12.2(2) XT3.

New Hardware and Software Features in Cisco IOS Release 12.2(2) XT2

No new hardware and software features are supported by the Cisco 1700 series for Cisco IOS Release 12.2(2) XT2.

New Hardware and Software Features in Cisco IOS Release 12.2(2) XT1

No new hardware and software features are supported by the Cisco 1700 series for Cisco IOS Release 12.2(2) XT1.

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

The following section describes the new software features supported by the Cisco 1700 series for Release 12.2(2)XT:

Cisco IOS Telephony Service

The Cisco IOS Telephony Service feature, a part of IP Telephony Services, provides basic Cisco IP phone call-handling capabilities in a LAN environment on the Cisco routers. This feature enables the Cisco multiservice routers to provide Cisco IOS Telephony Service for the Cisco IP Phone 7960, Cisco IP Phone 7940, Cisco IP Phone 7910, and Cisco IP Conference Station 7935. Cisco IOS Telephony Service also helps download phone software images and configures and manages the Cisco IP phones in a LAN, to accommodate the telephony system of a small office with a small number of extensions.


Note You need to purchase a feature license to turn this new feature on. You also need an account on Cisco.com to access the Cisco IP phone firmware versions.


For more information, see the document Cisco IOS Telephony Service:
http://www.cisco.com/univercd/cc/td/doc/product/access/ip_ph/srs/index.htm  

Survivable Remote Site Telephony—Version 2.0

The Survivable Remote Site Telephony (SRST) Version 2.0 feature provides the Cisco CallManager application with fallback support for Cisco IP phones attached to local Ethernet router interfaces. Prior to SRST, if WAN connectivity was lost between a remote branch office router and a remote primary, secondary, or tertiary Cisco CallManager, Cisco IP phones at the branch office were unusable for the duration of the failure. Using SRST, Cisco 1750 and 1751 series routers provide call-handling support for up to 24 Cisco IP phones and 48 lines when the WAN connection is down or connectivity to the Cisco CallManager is lost.

Cisco CallManager 3.0 with SRST automatically detects any failures between Cisco IP phones at remote sites and Cisco branch office multi-service routers, attached across a WAN. If a failure occurs, the SRST feature uses Simple Network Auto Provisioning (SNAP) technology to autoconfigure the branch router and provide call-processing service for the Cisco IP phones. During a failure, the Cisco IP phone displays a message indicating the Cisco IP phone is in the Cisco CallManager fallback mode and able to perform a limited set of functions. When WAN connectivity is restored, call-handling support for Cisco IP phones returns to the primary Cisco CallManager.


Note You need to purchase a feature license to turn this new feature on. You also need an account on Cisco.com to access the Cisco IP phone firmware versions.


The SRST feature supports up to six lines per phone, 24 phones, and 48 lines per system, with the following capabilities:

Redundant Call Processing if a WAN failure occurs:

Re-homing of IP phones to a local router

Local Extension-to-Extension calls

Extension-to-PSTN calls

No service disruption when the WAN link is restored

Calling Services during a WAN Failure:

Speed dial and last-number redial

Direct Outward Dial (DOD) calling

Direct Inward Dial (DID) calling

Caller ID and Automatic Number Identification (ANI) support

Calling Party Name

Distinctive Ringing

Limitations and Restrictions

The following sections contain Limitations and Restrictions for Cisco IOS Release 12.2(2)XT that can apply to the Cisco 1700 series. (Also, see the"Important Notes" section and the "Caveats" section.)

Hardware Equipment and Software Features Not Supported

Release 12.2(2)XT does not support the following hardware equipment or software features, which are supported by some other Cisco IOS software releases on Cisco 1700 series routers:

Cisco 1760 router

G-standard Symmetrical High bit-rate Digital Subscriber Loop (G.SHDSL) WAN interface card

Multiple 10Baset-T Ethernet WIC cards

Locations for WIC-1ENET Single Port Ethernet WICs other than Slot 0

Quality of Service (QoS) features on an ADSL link

Cisco Hoot and Holler over IP feature


Note The Hoot and Holler network is a multi-point, four-wire audio-conference network that is always up so that communication is enabled with the push of a button when needed.


Cisco IOS HTTP Vulnerability—Caveat CSCdr91706

A defect in multiple releases of Cisco IOS software causes a Cisco router or switch to halt and reload if the Cisco IOS HTTP service is enabled, you attempt to browse to http://router-ip/anytext?/, and you supply the enable password when prompted. This defect can be exploited to produce a denial of service (DoS) attack.

The vulnerability, identified as Cisco caveat CSCdr91706, affects virtually all mainstream Cisco routers and switches running Cisco IOS software releases 12.0 through 12.1, inclusive. This vulnerability can only be exploited if the enable password is known or not set. This caveat is not the same defect as caveat CSCdr36952.

The vulnerability has been corrected and Cisco is making fixed releases available for free to replace all affected Cisco IOS releases. Cisco urges all customers to upgrade to releases that are not vulnerable to this defect.

You are strongly encouraged to read the complete advisory, available at:
http://www.cisco.com/warp/public/707/ioshttpserverquery-pub.shtml. 

Important Notes

The following sections contain important notes about Cisco IOS Release 12.2(2)XT that can apply to the Cisco 1700 series. (Also, see the "Limitations and Restrictions" section and the "Caveats" section.)

IP Phone Quantity with 10BaseT Interfaces

When data and voice are running on a Cisco router with a 10BaseT interface, the 10 Mbps bandwidth of the interface might negatively impact voice traffic. In this case, Cisco recommends connecting a maximum of 12 IP phones to the router, to keep the 10BaseT connection from becoming a bottleneck. For interfaces of 100 Mbps or higher, up to 24 IP phones are supported.

Fan Operation in Cisco 1700 Series Routers

The fans in some Cisco 1700 series routers stay off until thermally activated. The fans in Cisco 1760 and 1760-V routers are always on.

Flash defaults to Flash:1 on Multipartition Flash

When using a multipartition flash card, the various flash partitions are referred to as "flash:1:", "flash:2:", etc. If you specify only "flash" in a multipartition flash, the parser assumes "flash:1:." For example, if you enter show flash all the parser defaults to "show flash:1: all" and only the flash information for the first partition displays. To see information for all flash partitions, enter the command show flash ?. After all of the valid partitions are displayed, enter the command show flash:xx: all on each valid partition.

Peak Cell Rate and Sustainable Cell Rate Values

On Cisco 1700 routers, specify the Peak Cell Rate (PCR) and Sustainable Cell Rate (SCR) as multiples of 32 Kbps. Other rates are treated as the next lower value of a multiple of 32. For example, an entered PCR value of 150 is considered 128.

Using the boot flash Command

Booting a Cisco 1700 series router with the commands boot flash or boot system flash results in unpredictable behavior. To work around this problem, be sure to enter a colon (:) following both commands (for example, boot flash: or boot system flash:.)

Caveats

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, and severity 3 caveats are the least serious of these three severity levels.

All caveats in Release 12.2 T are also in Release 12.2(2)XT. For information on caveats in Cisco IOS Release 12.2 T, refer to the Caveats for Cisco IOS Release 12.2 T document. For information on caveats in Cisco IOS Release 12.2, refer to the Caveats for Cisco IOS Release 12.2 document. These documents list severity 1 and 2 caveats, and are located on CCO and the Documentation CD-ROM.


Note If you have an account with CCO, you can use Bug Navigator II to find caveats of any severity for any release. You can reach Bug Navigator II on CCO at Software Center: Cisco IOS Software: BUG TOOLKIT: Cisco Bug Navigator II, or at http://www.cisco.com/support/bugtools/bugtool.shtml. 


Open Caveats—Cisco IOS Release12.2(2) XT3

This section documents possible unexpected behavior by Cisco IOS Release 12.2(2) XT3 and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdx04374

If CLNS is configured on the SVI interface (Vlan), the SNPA/MAC is not learned correctly by the router in which the SVI is present. This results in the router sending packets to a non-existent destination MAC address.

There is no workaround.

CSCdw46537

Symptom:

SPAN doesn't work after moving one port from multi span src ports. Disabling a source interface from a monitor session results in disabling the entire monitor session, not just the specified port.

Workaround:

If a particular source port is required to be removed form a SPAN session, stop the entire SPAN session and re-configure with only the required source ports.

CSCdw29549

Symptom:

Port security failed when configuring secure MAC addresses on an irrelevant port. When Port Security is configured on two interfaces P1 & P2, and secure MAC addresses M1 & M2are configured on interfaces P1 & P2 respectively, P1 should only allow packets with source MAC address M1 and P2 should only allow M2. But if a packet with secure MAC address M1 ingresses port P1, then the switch treats it like a station movement and allows the packet to be switched.

Workaround:

Cisco Systems recommends that when station movement takes place, the MAC addresses associated with the port should be cleared in the switch's tables before moving them to another port.

CSCdw14813

Symptom:

The command show mac count shows the wrong number of MAC addresses when compared to the count of addresses shown by the show mac command.

There is no workaround.

CSCdw20431

Symptom:

Traceback is seen on configuring the duplex and speed.

There is no workaround.

Resolved Caveats—Cisco IOS Release12.2(2) XT3

This section documents possible unexpected behavior by Cisco IOS Release 12.2(2) XT3 and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdv24152

Symptom:

A Cisco router that is running Cisco IOS Release 12.0(17)S and later 12.0 S releases may reset if Frame Relay has been incorrectly configured. If you apply the same data link control (DLC) value on an interface and on its subinterface twice in a row, the router may reset.

There is no workaround.

CSCdw14262

Symptom:

Cisco Voice over IP (VoIP) gateways that are running a Cisco IOS Release 12.2(1a) IP plus image may experience a high central processing unit (CPU) memory utilization condition at the CCH323_CT process.

There is no workaround.

CSCin02687

Symptom:

When using the Cisco 7200 series router as a Survivable Remote Site Telephony (SRST) and IOS telephony service router and making more than 30 three-party conference calls, the router crashes. The tracebacks point to the fast-ethernet interface that is being used to connect the router to the IP phones or rather the IP phone simulator.

Workaround:

Restrict the number of three-party conference calls.

CSCdv62649

Symptom:

The command ip tacacs source-interface does not work properly.

Workaround:

If configured to use loopback interface for tacacs packets, the router may still use the interface address.

CSCdw08182

Symptom:

The VWIC installed in NM-1FE2W appears in show diag response but not in the configuration.

The router is recognizing that it has a VWIC-1MFT-T1 in a NM-1FE2W in the show diag. The problem is that the T1 controller doesn't appear in the configuration. The FastEthernet is present.

There is no work-around.

CSCdw26331

Symptom:

A call to a busy FXS port produces an incorrect release cause code. Calls may receive a "no route to destination" message and an incorrect clearing cause code (instead of a user busy cause code) when calls are placed to a Foreign Exchange Station (FXS) on a busy interface. Depending on the equipment that is used, the caller may receive a "number unobtainable" message or fast busy tones instead of a busy tone when this condition occurs.

Workaround:

Add a huntstop on the dial peer that is assigned to the FXS interface.

CSCdw38767

Symptom:

Some ports on the NM-16ESW / NMD-36-ESW may not be assigned MAC addresses properly.

Conditions:

This occurs when the last digit of the base MAC address burnt in the NM cookie is in the range 0xF0- 0xFF for NM-16ESW and range 0xDA-0xFF for NMD-36-ESW.

Workaround:

None.

CSCdw46803

Symptom:

After a Cisco 1751 router that is running Cisco IOS Release 12.2(2)XT and that has a BRI network termination/traffic engineering (NT/TE) is reloaded, Layers 1 and 2 may become deactivated.

Workaround:

Enter the shutdown interface configuration command followed by the no shutdown interface configuration command on the BRI interface.

CSCdw51152

Symptom:

PCI Fatal Error on DMA CH1

When access to Flash/NVRAM occurs as a result of write memory or show run commands, and the CPU utilization is high due to heavy packet traffic, this error message can sometimes occur.

This is due to the PCI device timing out on the PCI bus waiting for DMA access to memory.

Workaround:

CSCdu53333

Symptom:

A Cisco router that is running Cisco IOS Release 12.2(1) or 12.2(0.5g) may experience digital signal processor (DSP) reloads or fail to respond after the following DSP Timeout error messages are displayed:

%VTSP-3-DSP_TIMEOUT: DSP timeout on event 6: DSP ID=0x1: DSP error stats, chnl info(5, 13, 0) %VTSP-3-MSGSNDFAIL: channel:5/0:15 (54516) DSP ID:0x1 Message ID:0x47

The problem is intermittant, and DSPs may hang indefinitely as rarely as only once every few weeks. The problem is likely to appear when T.38 fax mode is used and is likely to appear when "codec complexity medium" is configured for the voice card and there is frequent switching between the fax and voice modes.

Workaround:

This DSP firmware defect is fixed in DSP Release 3.6.15 / VCWare Release 9.19 and DSP Release 3.4.49 / VCWare Release 7.38, as well as newer versions of these firmware releases.

CSCdw54986

Symptom:

A router with primary-ni switchtype will not be able to interoperate with switches that sends CLID/CLIP/CLIR information in FACILITY messages. The router does not accept the FACILITY and disconnects the call.

Workaround:

None

CSCdw57198

Symptom:

SRST router with FXO ports typically has a connection plar (opx) to route an incoming call on the port to an extension in the router. With this problem, the incoming call cannot be transferred.

There is no workaround.

CSCdw62829

Symptom:

The High-Density Analog Voice/Fax Network Modules (NM-HDA) for the Cisco 2600 series and Cisco 3600 series routers support Local Voice Busyout (LVBO) features. The busyout monitor command can be configured under NM-HDA voice-ports to permit busyout monitoring of local interfaces or remote IP interfaces via Service Assurance Agent (SAA) probes. These features can be configured and can be saved to Non-Volatile RAM (NVRAM) successfully, but on a router reload, the boot-time parser rejects the busyout monitor commands.

Any busyout monitor command configured under a voice-port on a NM-HDA will disappear from the running-configuration if the router is rebooted. This problem does not occur on VIC-2E/M, VIC-2FXS, and VIC-2FXO voice-ports housed on the NM-1V and NM-2V products.

Workaround:

Issue a copy startup-config running-config to re-assert the missing commands.

CSCdw70410

Symptom:

A Cisco router may reload after a high-density analog voice or fax network module (NM-HDA) that is installed in a slot is replaced by another NM-HDA that has a different hardware configuration.

Workaround:

Use a replacement card that is the same as the original card. This condition will not occur if a card that is the same as the original is used or if a differently configured card is placed in a different slot.

CSCdw71436

Symptom:

Under rare circumstances, a Cisco router may reload because of a segmentation violation (SegV) when fax calls are present.

There is no workaround.

CSCdw73302

Symptom:

When using a TCL IVR 2.0 application on a Cisco voice gateway for 2-stage calls, the configured translation rule may be applied for each received digit, instead of only for the initial digit.

Workaround:

None

CSCdw73507

Symptom:

Ringback is not available for calls coming in from a PSTN. IP phones do not ringback on the network side. When a call comes in from a PSTN, the call should tell the PSTN end so that it can generate ringback on behalf of the IP phones by sending progress ind as 3.

Workaround:

None

CSCdw75065

Symptom:

Alignment traceback when transfer and conference call. Tracebacks are observed during conference and at times, during regular calls. The tracebacks are on misaligned accesses to memory.

Workaround:

They are subsequently corrected by the hardware but prints to console are annoying and can be viewed as serious potential issues.

CSCdw82677

Symptom:

Bad voice-quality during conference call. This happens when a Survivable Remote Site Telephony (SRST) ITS GW with loop-back-dns is used in conferencing with a remote GW and where a mis-match of codec types results if the GWs do not have the same codec type configured. Conferencing a-law and u-law mixes doesn't work as some legs in ITS end up with a-law and some with u-law which gives bad voice quality.

Workaround:

This fix is only applicable for a network that has a mixture of A-law and U-law codecs configured in the network. Configure all gateways in the network to use same codec type of either A-law or U-law.

CSCdw84594

Symptom:

Show diag for Cisco 2600 series routers gives wrong values for NMs which uses TLV_IDPROM. This problem is only on Cisco 2600 series platform

Conditions:

While issuing sh diag <slot> command, HDA uses TLV_IDPROM. The hardware version, revision information, and other conditions are displayed wrongly.

Workaround:

None

CSCdw85359

Symptom:

Caller ID is discarded when an incoming PSTN call through FXO-M1/FXS-M1 is transferred to another number. The Caller-ID displayed after the transfer is "From Private....".

Workaround:

None:

CSCdx01445

Symptom:

The port does not go on-hook when a supervisory disconnect tone is sent from the PSTN. When call comes in through FXO port to IP Phone, the IP Phone goes into Alerting state. If the caller hangs up at this point, the PSTN sends a supervisory disconnect tone to the FXO where no action is taken which results in not freeing up the port immediately.

Workaround:

None

CSCuk31298

Symptom:

The IP phone locks during a call to a call forward busy number. This condition occurs in a setup whereby the call forward busy feature is configured using the Cisco IOS Telephony Service (ITS) on an IP phone (phone A) to a second IP phone (phone B). When a call is made from phone A to another phone (phone C), the call can be answered normally.

When a second call is placed from another phone to phone A via a loopback-directory number (loopback-dn), the call is forwarded to phone B. As this call is received, the original call is incorrectly cleared by the node on phone C while the call is still shown as "up" on phone A. When this condition occurs, phone A is no longer able to place or receive calls and has to be powered down to be restored to working condition.

Workaround:

This condition affects only the first IP phone in the internal control table on the router. The first IP phone is typically indicated as "ephone 1" when the show ephone EXEC command is issued.

To prevent this condition from occurring when the router is operating in the ITS mode, add a dummy phone entry as the first IP phone or "ephone 1" in the internal control table on the router to prevent an active phone from being listed as the first IP phone in the internal control table of the router.

Reload the router to ensure that the dummy phone occupies the first position in the control table. There is currently no workaround to this condition if the router is operating in the Survivable Remote Site Telephony (SRST) mode (call manager fall back).

CSCuk31300

Symptom:

Ringing presented to caller before state of called number is known.

When using loopback-dns for outgoing calls, the router presents a ringing tone to the IP phone caller as soon as the call has been routed and before the state of the called number is known.

If the called number is busy, this can result in a ringing and then busy tone being played to the caller. This does not happen if loopback-dns are not used, or if they are used for incoming calls.

Workaround.

Do not use loopback-dns for outgoing calls.

CSCuk31512

Symptom:

On a miss dialed call transfer, a new call shows previously dialed digits.

When a Keyswitch IP phone user receives an incoming call, and they then attempt to transfer that call, but while dialling they realize they are dialling a wrong number, the transferrer has two options. If they incorrectly select "New Call", the phone displays the previous dialed digits. If the caller then dials more digits, these appear after the previous digits. The phone however only dials the digits presented after the "New Call" button was pressed, and the call is successful.

Workaround.

None

CSCuk31658

Symptom:

On three-way calls setup by a Survivable Remote Site Telephony / Keyswitch IP phone, if the second call leg to be setup clears their call, the speech path from the IP phone where the conference was setup to the other phone is lost. The problem is observed only when the second call clears, and only if another IP phone is used in addition to the IP phone which set the conference up. Voice path is re-established if the phone that initiated the conference temporarily places the remaining caller on-hold and then immediately resumes the call.

Workaround:

None

CSCdw62185

This release integrates the DSPware 3.6.15 release. Upgrading to the DSPware 3.6.15 release to fix CSCdu53333 (dsp timeout) remedies the voice quality problem in this caveat.

CSCdr91706

A defect in multiple releases of Cisco IOS software causes a Cisco router or switch to halt and reload if the Cisco IOS HTTP service is enabled, you attempt to browse to http://router-ip/anytext?/, and you supply the enable password when prompted. This defect can be exploited to produce a denial of service (DoS) attack. See the "Cisco IOS HTTP Vulnerability—Caveat CSCdr91706" section.

CSCdw04503

Call-forward commands not entered for E164 dial-peers.

When dialplan pattern is configured for the local IP Phones, the existing call-forward commands under ephone-dn are not entered under the E.164 dial-peers created by the dialplan pattern command. This can cause a call not getting forwarded if you dial the entire E164 number.

This problem happens only if you add or edit the existing dialplan pattern with call-forward commands already in place. One way to avoid this problem is to configure the right dialplan pattern before configuring the call-forward commands. Additionally, if you modify the dialplan pattern commands, configure the call forward commands again under ephone-dn. This creates the call-forward commands under the E164 dial-peers created.

CSCdv78130

Inconsistent music on hold (MOH) during conference.

Music on hold works inconsistently in certain conditions. A calls B and conferences to C. B puts the conference on hold. Both A and C hear the MOH. B resumes the call and after a while puts the conference on hold again. Now only A (initiator) hears the MOH.

There is no workaround.

CSCdv72916

Remote branch Analog Phone to IP Phone call disconnected during CM reconnect.

Calls from Analog Phone to IP Phone during call-manager-fallback mode may get disconnected when the WAN link to CM comes back up. If a call is made in "normal mode" and the WAN link fails, the call stays up even though the WAN link failed. If the WAN link comes back up during the call and the call is between two IP phones or two analog phones, the call is not dropped. However, if the call is between an IP phone and an analog phone, the call is dropped.

There is no workaround.

Resolved Caveats—Cisco IOS Release 12.2(2) XT

There are no resolved caveats specific to Cisco IOS Release 12.2(2) XT that require documentation in the release notes.
