New and Changed Information

The following sections list the new hardware and software features supported by the Cisco 3600 series for Release 12.0(5)XK.

Digital T1 Packet Voice Trunk Network Modules on Cisco 2600 and 3600 Series Routers

Digital T1 packet voice trunk network modules for Cisco 2600 and 3600 series routers allow enterprises or service providers, using the equipped routers as customer premises equipment, to deploy digital voice and fax relay. These modules receive constant bit-rate telephony information over T1 interfaces and can convert that information to a compressed format, so that it can be transmitted as voice over IP.

The following high-density T1 network modules are available:

• 1-port 24-Channel T1 High-Density Voice Network Module (NM-HDV-1T1-24)

• 1-port Enhanced 24-Channel T1 High-Density Voice Network Module (NM-HDV-1T1-24E)

• 2-Port 48-Channel High-Density Voice Network Module (NM-HDV-2T1-48)

T1 digital voice over IP includes the following functionality:

• T1 Channel Associated Signaling (CAS) for the following line-signaling types:

  • rEceive and transMit or Ear and Mouth (E&M) immediate start

  • E&M wink start

  • E&M delay start (also called "dial repeating")

  • Foreign Exchange Station (FXS) and Foreign Exchange Office (FXO) loop start

  • FXS and FXO ground start

• Dynamic bandwidth allocation using voice activity detection (VAD)

• Drop-and-Insert capability, allowing the interchange of time-division multiplexing (TDM) slots between the ports on a two-port T1 multiflex trunk voice/WAN interface card installed in a digital T1 packet voice trunk network module

• Support for a wide range of International Telecommunication Union (ITU-T) G-series compression specifications, including:

  • G.711 A Law at 64,000 bps

  • G.711 u Law at 64,000 bps

  • G.723.1 Annex A at 5,300 bps

  • G.723.1 Annex A at 6,300 bps

  • G.723.1 at 5,300 bps

  • G.723.1 at 6,300 bps

  • G.726 at 16,000 bps

  • G.726 at 24,000 bps

  • G.726 at 32,000 bps

  • G.728 at 16,000 bps

  • G.729 at 8,000 bps

  • G.729 Annex A at 8,000 bps

  • G.729 Annex B at 8,000 bps

  • G.729 Annex B with Annex A at 8,000 bps

• Depending on codec complexity, either 30 or 60 channels of compressed voice

• High-quality voice endpoint-standard features, such as high-quality echo cancellation, silence suppression, comfort noise generation, and DTMF relay

• Group 3 fax relay

This feature is supported on the following platforms:

• Cisco 2610

• Cisco 2611

Multiport T1/E1ATM Network Modules with Inverse Multiplexing over ATM on Cisco 2600 and 3600 Series Routers

Digital T1 packet voice trunk network modules allow Cisco 2600 and 3600 series routers to provide T1 connectivity to PBXs or to a central office (CO). With digital T1 connectivity, Cisco 2600 and 3600 series routers can provide greater voice density for enterprise and service provider VoIP networks than they could before. A digital T1 packet voice trunk network module is a complete solution, made up of a network module with installed packet voice data modules (PVDMs), and one T1 multiflex trunk voice/WAN interface card with either one or two T1 ports. The T1/E1 multiflex trunk interface cards are dual-mode T1 or E1 interfaces in a VWIC (Voice/WAN Interface Card) form for voice, data, and integrated voice/data applications. The following T1/E1 multiflex trunk interface cards are available:

• 1-port T1 multiflex trunk interface (VWIC-1MFT-T1)

• 1-port E1 multiflex trunk interface (VWIC-1MFT-E1)

• 2-port T1 multiflex trunk interface (VWIC-2MFT-T1)

• 2-port E1 multiflex trunk interface (VWIC-2MFT-E1)

• 2-port T1 multiflex trunk interface with Drop and Insert (VWIC-2MFT-T1-DI)

• 2-port E1 multiflex trunk interface with Drop and Insert (VWIC-2MFT-E1-DI)

The T1/E1 VWICs support the following T1/E1 functionality:

• Single- or dual-port T1/E1 functionality

• Structured or unstructured T1/E1 functionality

• Drop and Insert (also called TDM Cross-Connect) between the T1/E1 ports on dual-port cards, used to hairpin bearer channels to a media gateway device and allowing the interchange of time-division multiplexing (TDM) slots between the ports on a two-port card

This feature is supported on the following platforms:

• Cisco 2610

• Cisco 2611

• Cisco 2612

• Cisco 2613

• Cisco 2620

• Cisco 2621

• Cisco 3620

• Cisco 3640

• Cisco 3660 series

Caveats

Caveats describe unexpected behavior or defects in Cisco IOS software releases. For information on caveats in Cisco IOS Release 12.0 T, refer to the Caveats for Cisco IOS Release12.0 T  document, which is located on CCO and the Documentation CD-ROM.

All caveats in Release 12.0 are also in Release 12.0 T.

For information on caveats in Cisco IOS Release 12.0, please refer to the Caveats for Cisco IOS Release 12.0  document, which is located on CCO and the Documentation CD-ROM. These release notes list severity 1 and 2 caveats affecting all maintenance releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.

Caveats for Release12.0(5)XK

This section describes possibly unexpected behavior by Release 12.0(5)XK. Unless otherwise noted, these caveats apply to all 12.0 releases up to and including 12.0(5)XK.

Basic System Services

• CSCdk33632

Under noisy line conditions, a giant packet followed by a runt packet on a serial line causes a Cisco 2600 router to crash or report spurious accesses.

• CSCdk72065

The correct buffer size should be determined before zeroing out the buffer.

• CSCdm07937

When a customer repeatedly executed the command write term, a GSR shut down due to environmental alarms. The env table, which is used to compare with measured readings, was corrupted.

• CSCdm11467

An NTP-related SegV Exception occurs in peer_list_sum.

When NTP private mode is used with control type messages for remote queries, a router can crash or issue traceback messages.

• CSCdm45305

On the Cisco MC3810, comfort-noise generation cannot be disabled.

Workaround: Disable VAD, as comfort noise is only applicable when VAD is engaged.

IBM Connectivity

• CSCdm11922

Environment: DLSW direct encapsulation serial link WAN with Ethernet LAN on one side and Token Ring LAN on the other.

Observed Problem: Connections are only established from the Token Ring side.

Workaround: Raise the MTU of the serial WAN to 1800 bytes or so.

Fix: The code will be altered to allow connections from Ethernet end stations even with the WAN MTU at 1500. Network administrators must make sure that no packets of 1500 bytes (pre-encapsulation) come in off the LAN. This sets up the possibility of hung sessions with oversized packets, but it allows well-configured networks to run without modification.

• CSCdm34552

A router crashed from a bus error at PC _lnm_add_entry, probably because it received a frame on its Token Ring interface that pertains to LNM and also has its RIF length greater than 7 hops.

Workaround: Try deactivating LNM REM with the no lnm rem command.

Interfaces and Bridging

• CSCdj54192

If an interface on a HSSI 1 port (PA-H or H1T+) card goes down/down and you see the following error message, that you may be experiencing this problem:

%MUSELIX-1-STOPFAIL: XXXX: Stop Failed at disable port (XXXX = the interface affected) %MUSELIX-1-STARTFAIL: XXXX: Start Failed at enable port MUESLIX-1-FAILURE_CAUSE: SerialX/X:

This problem is caused by several factors.

Once it falls into this state, execute the following (undocumented) test commands (<CR> is a carriage return):

term len 0<CR> sh cont h 1/0<CR> test tpu b<CR> 1/0<CR> g<CR> x<CR> y<CR> r<CR> s<CR> 3<CR> q<CR> test tpu b<CR> 1/1<CR> g<CR> x<CR> y<CR> r<CR> s<CR> 3<CR> q<CR> test len 24<CR>

An example of this process can be obtained by using Bug Navigator II.

---

• CSCdm46735

A PA-4R-DTR port may reset under the following circumstances:

• A high rate of traffic (200 pps or better) traversing the port

• The PA-4R-DTR port as the Active monitor of the physical ring

• An event on the ring forces the active monitor to purge the ring.

When this problem occurs, the PA-4R-DTR port resets, and the ring experiences a beacon.

Workaround: Make sure the DTR port is not the active monitor on the ring. Ensure that the MAC address of the DTR card is not the highest MAC address on the physical ring.

• CSCdm60960

With the following input-type-list, the router doesn't respond to an ARP request. Without the list or with the addition of a line for ARP packets, it works. You can still ping the interface IP address but not the HSRP address.

interface Ethernet0/0 ip address 13.13.13.1 255.255.255.0 standby 143 priority 110 preempt standby 143 ip 13.13.13.254 bridge-group 1 bridge-group 1 input-type-list 201 !

Workaround: Delete the input access lists on the bridge interface or permit the type 0x0806 in the access list.

IP Routing Protocols

• CSCdk08868

Symptom: Lock and Key idle timer is taking too long to timeout. The idle timeout, as configured by the autocommand access-enable command, is taking too long to time out. While the logging is on for access list hits, the time that it takes to idle out (with no access list hits) is up to two times the length configured.

Conditions: If the dynamic entry is created by the Lock and Key feature that requires the user Telneting into the router, then the idle timeout takes up to two times the length configured by using the autocommand access-enable host timeout minutes command.

Workaround: Suggest customers that are running 11.1 series of images with this problem to upgrade to 11.2.

Further problem description:

There are two fixes for this problem.

The first problem was that the router refreshes the last-hit timer against all the traffic coming into the interface instead of refreshing the timer only when the traffic matched the created dynamic access list.

The fix is to perform the checking of the source address of packets against the source address in the dynamic access list. If there is a match, then the last hit time stamp is refreshed.

The second problem is that when the last packet comes in really close to the creation time of the dynamic entry, the new delta time for the next expiration could be less than zero, due to the real timer event being processed later than the exact scheduled timeout. The timer routine figures out the next expiration time by using the total idle timer value minus the time elapsed since the last reference timestamp. But the timer routine is scheduled later than the expected expiration time due to other activities in the router.

last reference calculated expiration time (3 minutes) | (2 seconds) | v v |----------|----------|---------|----- ^ ^ | | +-- dynamic ACL is created +-- the timeout event get processed (3 minutes and 5 seconds)

The elapsed time (now timestamp minus last reference timestamp) is 3 minutes and 3 seconds (3 minutes 5 seconds minus 2 seconds), which is greater than 3 minutes as shown above. We should only extend the expiration time for one minute (due to the timer unit is 1 minute), but the old implementation extended a whole idle time (3 minutes) instead of 1 minute.

The fix for the second problem is to set the next expiration time of the idle timeout to be 1 minute from now.

Miscellaneous

• CSCdk03906

When running NAT and encryption, FTP fails, but Telnet and ping work. The TCP checksum is not calculated correctly. Removing NAT or encryption resolves the problem.

For performance reasons, decryption is not done until the packets are switched to the output interface. This caused the problem with IOS NAT, because NAT may need to do the payload translation for certain protocols. The affected protocols include FTP and NetBios, for example.

• CSCdk29115

When you configure Bisync (encapsulation bstun) with the ASCII character set (bsc char-set ascii) on the first port of a serial WIC (1T, 2T, or 2A/S) in WIC slot 0 of a Cisco 2600 series router, only the first character of each frame is received, and the BSTUN tunnel is not established. This only affects Bisync mode when it is configured with the ASCII character set. Other encapsulations are not affected, and use of the EBCDIC character set with Bisync works correctly.

For the first serial port in WIC slot 0, the parity detection is not configured correctly for Bisync in ASCII mode. The first character of each frame generates a parity error that causes the receiver to discard the frame after the first character received.

Workaround: Use a different serial port, either the second serial port (port 1) on a 2T or 2A/S WIC in WIC slot 0, or any serial port in WIC slot 1. If you have only one serial WIC, moving it from WIC slot 0 to WIC slot 1 fixes this problem.

• CSCdk34543

Encryption does not work properly with following hardware combination: 7500, VIP2-40, PA-2CE1 (or PA-CE1) when the channelized E1 interface is configured for Frame Relay.

The problem is related to distributed services, and only the channelized E1 PAs on the VIP2-40 are affected.

Workaround: Use VIP2-15 instead of VIP2-40.

• CSCdk46853

In Release 11.2P and 11.3, when Fast Ethernet subinterfaces are configured for encryption and the crypto map is only applied to the main interface with the IP address configured in the subinterface, the packets can be switched in the clear. In Release 12.0, enabling CEF can cause the packets to be dropped.

• CSCdk55110

When tunneling IPX over an IP tunnel, and when using an extended inbound access list for IP on the tunnel interface, the IPX traffic is blocked by the access list.

Workaround: Add a permit gre statement in the extended access list.

• CSCdk66567

If Token Ring is the endpoint of an encrypted tunnel, extra packets are generated.

Symptoms are a high CPU load (mainly taken by the crypto engine) and bogus addresses when you enable the debug tunnel command.

Workaround: Use the interface command tunnel sequence-datagrams on both endpoints of the tunnel.

• CSCdk79294

A PA-A3 ATM Enhanced Port Adapter may cause a VIP crash. Console messages like the following one appear:

%ATMPA-3-BADPARTICLE: ATM0/0: bad rx particle 0x605C7C80 index 282 -Traceback= 6015D550 60170C50 60171B78 600A8FB4

The show diag command for that VIP displays an address error (load or instruction fetch) exception.

• CSCdm30103

The Cisco 1700 Fast Ethernet interface receives input errors when small packets (less than 200 bytes) are received while the interface is receiving 500 packets per second and running fast switching.

• CSCdm31275

A Cisco AS5300 may crash when running very high traffic (60 pps on all 96 channels) with calls are being setup and torn down continuously.

• CSCdm39879

If VAD is enabled on VoFR/VoATM calls on a Cisco MC3810, there may be significant voice quality degradation.

Workaround: Disable VAD by placing a no vad statement in all VoFR or VoATM dial peers.

• CSCdm45085

If the IDB is not defined, IPSec crashes. There is no known workaround. See CSCdm52531 for a description.

• CSCdm55716

An ATM subinterface drops packets when distributed CEF is disabled

The problem only occurs on subinterfaces created after DCEF was on and then turned off.

Workaround: Enable and then disable DCEF after creating a new subinterface.

• CSCdm57609

PA-A2 may cause memory corruption if you are using SVCs with ARP server when you shut down the interface.

• CSCdm60622

SS-EVAL GWs running 12.0(5)T ignore or discard RAS messages that contain cleartokens other than settlement cleartokens. This can prevent the establishment of calls when interacting with vendor systems that include cleartokens where the OBject IDs in the nonStandarParameter fields are coded to be anything other than OSP cleartokens.

Novell IPX, XNS, and Apollo Domain

• CSCdm56600

Images without the IPX-EIGRP subsystem have high CPU load due to continually triggering an attempt to process EIGRP-specific service information when no information is present. There is no workaround.

Wide-Area Networking

• CSCdm12648

All platforms running MLP can encounter a transient error condition where no links are assigned to a multi-link bundle.

• CSCdm48047

A Cisco 4000 series router can crash when configuring LECS, LES/BUS, and LEC on the router. This crash occurs on 11.3(9)WA4(11.1). There is no workaround.

• CSCdm57650

In a multi-chassis MLP stack group where two stack group members cross project MLP link interfaces, one of the stack group member may crash. There is no workaround.

• CSCdm61038

It is not possible to change the status of channel 31 (the 32nd channel) in an ISDN E1.

CCO serves a wide variety of users through two interfaces that are updated and enhanced simultaneously: a character-based version and a multimedia version that resides on the World Wide Web (WWW). The character-based CCO supports Zmodem, Kermit, Xmodem, FTP, and Internet e-mail, and it is excellent for quick access to information over lower bandwidths. The WWW version of CCO provides richly formatted documents with photographs, figures, graphics, and video, as well as hyperlinks to related information.

You can reach CCO in the following ways:

• WWW:  http://www.cisco.com

• Telnet:  cco.cisco.com

• Modem:  From North America, 408 526-8070; from Europe, 33 1 64 46 40 82. Use the following terminal settings: VT100 emulation; databits: 8; parity: none; stop bits: 1; and connection rates up to 28.8 kbps.

Documentation CD-ROM

Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more current than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription. You can also reach Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.

If you are reading Cisco product documentation on the World Wide Web, you can submit comments electronically. Click Feedback in the toolbar and select Documentation. After you complete the form, click Submit to send it to Cisco. We appreciate your comments.
