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

Advanced Integration Modules (AIM) and Network Module (NM)

The data encryption modules, AIM-VPN/HP for the Cisco 3660 and NM-VPN/MP for the Cisco 3620 and 3640, are hardware Layer 3 (IPSec) encryption modules and provide DES(56-bit) and 3DES(168-bit) IPsec encryption for multiple T1s or E1s of bandwidth. This level of performance is a dramatic increase over that achievable when running IPSec in software on the main CPU of the Cisco 2600 or 3600. These products also have hardware support for DH, RSA, and DSA key generation.

In addition to encryption, the data encryption AIM is intended to increase the security of passwords and various encryption keys over that provided by IOS software and the platform hardware. Specifically, these products have been submitted for Level 2 of the Federal Information Processing Standard (FIPS) 140-1 in general as well as more stringent levels for some parameters such as Level 3 tamper resistance.

VIC-2BRI-NT/TE

The ISDN BRI NT/TE voice interface card (VIC-2BRI-NT/TE) for the Cisco 3600 series enables Cisco IOS software to replicate the public switched network interface to a PBX that is compatible with European Telecommunications Standards Institute (ETSI) NET3 and QSIG switch types.

In the past, customers with PBXs that implement only the BRI TE interface have had to make substantial hardware and software changes on the PBX to implement the NT interface. The implementation of an NT interface on the router allows the customer to connect ISDN PBXs and key systems to a multiservice network with a minimum of configuration changes on the PBX.

New Software Features in Cisco IOS Release 12.1(3a) XI1

The following new software features are supported by the Cisco 3600 series for Cisco IOS Release 12.1(3a) XI1.

AIM-VPN/BP, AIM-VPN/HP,NM-VPN/MP

This feature supports the data encryption with the Advanced Integration Modules (AIM) and the Network Module (NM) to provide hardware-based encryption for the Cisco 2600 and 3600 series routers. This feature requires both Cisco IOS Release 12.1(3a) XI1, or later and one of the Cisco IOS feature sets that includes IPSec.

Interworking Signaling Enhancements for H.323 and SIP VoIP

The Interworking Signaling Enhancements for H.323 and SIP VoIP feature enables VoIP networks to properly signal the setup and tear-down of calls when interworking with PSTN networks. These enhancements ensure that in-band tones and announcements are generated when needed so that the voice path is cut-through at the appropriate point of call setup and that early alerting (ringing) does not occur. In addition, support for network-side ISDN and the reducing of speech clipping is addressed.

Multimedia Conference Manager with Voice Gateway image with RSVP to ATM

The Multimedia Conference Manager with Voice Gateway image with RSVP to ATM feature is designed to deliver Cisco's H.323 gatekeeper, proxy and voice gateway solutions with routing as a single Cisco IOS image. In addition, the ability to map H.323 Resource Reservation Protocol (RSVP) reservations to ATM VBR SVCs (switched virtual circuits) has also been incorporated for guaranteeing QoS (quality of service) over ATM backbones for video applications.

VIC-2BRI-NT/TE, MC3810-BVM4-NT/TE

This feature supports the ISDN BRI NT/TE voice interface card (VIC-2BRI-NT/TE) for the Cisco 2600 and Cisco 3600 series and the ISDN BRI Voice Module (BVM4-NT/TE) for the Cisco MC3810. These enable Cisco IOS software to replicate the public switched network interface to a PBX that is compatible with European Telecommunications Standards Institute (ETSI) NET3 and QSIG switch types.

In the past, customers with PBXs that implement only the BRI TE interface, have had to make substantial hardware and software changes on the PBX to implement the NT interface. The implementation of an NT interface on the router now allows the customer to connect ISDN PBXs and key systems to a multiservice network with a minimum of configuration changes on the PBX.

VoIP Call Admission Control using RSVP

The VoIP Call Admission Control using RSVP feature synchronizes Resource Reservation Protocol (RSVP) procedures with H.323 Version 2 (Fast Connect) setup procedures to guarantee that the required Quality of Service (QoS) for VoIP calls is maintained across the IP network. Prior to Cisco IOS Release 12.1(3a) XI1, VoIP gateways used H.323 Version 1 (Slow Connect) procedures when initiating calls requiring bandwidth reservation. This feature, which is enabled by default, allows gateways to use H.323 Version 2 (Fast Connect) for all calls, including those requiring RSVP.

Important Notes

This section contains important information about use of your Cisco IOS Release 12.1(3a) XI1 software. The last maintenance release of the Cisco IOS Release 12.0T release train is 12.0(7)T. The migration path for customers needing bug fixes for Cisco IOS Release 12.0 T features is 12.1 Mainline. Cisco IOS Release 12.1 Mainline has the complete feature content of 12.0T and this release will eventually reach General Deployment (GD).

Cisco IOS Release 12.1 T begins with the same set of features as the Cisco IOS Release 12.1 mainline but will continue to add features.

Caveats

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.

This section contains open and resolved caveats for Cisco IOS Release 12.1(3a) XI1. All caveats in Release 12.1 and Release 12.1 T are also in Release 12.1(3a) XI1.

For information on caveats in Cisco IOS Release 12.1 and Release 12.1 T, see Caveats for Cisco  IOS Release 12.1 , which lists severity 1 and 2 caveats, and is 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. To reach Bug Navigator II, go to CCO and press Login. Then go to Software Center: Cisco IOS Software: Cisco Bugtool Navigator II. Another option is to go to http://www.cisco.com/support/bugtools (you must have an account on CCO to access this site).

Open Caveats—Release 12.1(3a) XI1

  The caveats listed in this section are open in Cisco IOS Release 12.1(3a) XI1.
  On a Cisco 3600 router functioning as a gateway, if a gateway-priority option has been set with the zone prefix command, the router might pause for a short while, followed by a "watchdog timer" interrupt, after which the router reloads.
  This problem also depends on the order in which the gateway is defined and the order in which it registers with the gatekeeper.
  There is no workaround, other than to try altering the configuration and the order of registration.
  A Cisco 3600 router running encryption may get tracebacks with the following error messages:
    %SYS-2-INLIST
  and
    %SYS-2-BADSHARE.
  There is no workaround.
  On a Cisco 3600 router configured with c542-based DSP modules from which the voice traffic originates and terminates, and with the Compressed Real-Time Transport Protocol (CRTP) configured for Fast Switching, the voice quality might degrade rapidly to the point where only noise is heard and the fast-switched packets do not go through.
  When a call is made and with the debug ip rtp errors command enabled, the following output is seen on the console of the router:
    RHC: hash(fast) negative cache candidate
RHC: hash(fast) adding to negative cache 1
RHC: hash(fast) negative cache candidate
  This is often followed by the following message:
    %C542-1-NO_RING_DESCRIPTORS: No more ring descriptors available on 1 slot
  Workaround: Turn off fast switching using the no ip route-cache command.
  On a Cisco 3600 router configured as a voice gateway, the adaptive de-jitter buffer calculates the depth too small to cope with the jitter actually seen through the network, which might result in poor voice quality. The de-jitter buffer is a buffer on the digital signal processor (DSP) that copes with variable-packet delivery so that voice samples can be played at a constant rate over the audio path.
  Workaround: Configure the following commands on all voice ports (note that the values 220 and 100 are just examples, see the paragraph below the commands):
  voice-port 1/1
playout-delay maximum 220
playout-delay nominal 100
playout-delay mode fixed
  The values 220 ms and 100 ms were used for the maximum de-jitter buffer depth and nominal depth in this example. These values can vary depending on the actual jitter in a network.
  When a Cisco 3600 router functioning as a voice gateway receives an incoming VOIP call, the voice activity detection (VAD) property will be set based on the remote open logical channel rather than on the local configuration of the dial-peer. Therefore, the VAD's configuration of the incoming call as defined in the dial-peer has no effect.
  There is no workaround.
  On a Cisco 3600 router, a call on an ISDN ports fails if two calls are being attempted on the two BRI channels at the same time, that is, if port A and B have established an ISDN connection and port A makes a call to port B at the same time that port B makes a call to port A, one of the calls fails.
  An additional condition for this problem to occur is that the setup specifies "Any Channel" in the channel ID Information Element (IE).
  Workaround: Shut down the interface to clear the condition.
  When the Resource Reservation Protocol (RSVP)-to-ATM switched virtual circuit (SVC) Mapping feature is used, a small amount of memory leak may occur every time an SVC is torn down. After the router has performed this activity many times, it will run out of memory, become inoperational, and might reload.
  Workaround: Reload the router periodically, depending on the volume of traffic that triggers the SVC setup and tear-down. The estimated rate of memory leak is about 140 KB per 1000 setups and tear-downs.

Closed or Resolved Caveats—Release 12.1(3a) XI1

The caveats listed in this section are closed or resolved in Cisco IOS Release 12.1(3a) XI1.

  On a Cisco 3600 router, the "maximum frames per packet" audio-capability value of the H.245 open logical channel (OLC) is statically defined and not dynamically updated to reflect the codec bytes configuration. The codec bytes (payload) can be configured under the dial peer and under the voice-class codec configuration.
  Another related problem on the local gateway (GW) is that the GW does not consider the remote endpoints of the "maximum frames per packet" audio-capability value of the H.245 test and control system (TCS) when the GW opens a logical channel to that remote endpoint. The local GW will open a logical channel and then transmit packets larger than the remote endpoint defined as its maximum receive-size capability.
  Finally, upon payload negotiation, the Digital Signal Processor (DSP) should indicate to transmit/receive at the dynamically determined payload size, instead of the configured bytes.
  This has been resolved in Cisco IOS Release 12.1(3a) XI1.
  If a Cisco Call Manager sends a notify message without the User-to-User Information Element (UUIE) to a Cisco 3600 router functioning as a voice gateway, and the display option is enabled, the voice gateway decodes the notify message incorrectly, which might result in the call being disconnected. In addition, the voice getaway might send a status message indicating that the UUIE is missing.
  This has been resolved in Cisco IOS Release 12.1(3a) XI1.
  On a Cisco 3600 router functioning as a voice gateway under a heavy workload, if the H245 control channel is opened with the keepalive option enabled on the Transmission Control Protocol (TCP) socket that is being used, the call might be disconnected.
  This has been resolved in Cisco IOS Release 12.1(3a) XI1. The solution includes the disablement of the TCP keepalive option for the H245 control channel.
