Feature Support
Cisco IOS software is packaged in feature sets that consist of software images that support specific platforms. The feature sets available for a specific platform depend on which Cisco IOS software images are included in a release. Each feature set contains a specific set of Cisco IOS features.
CautionCisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to U.S. 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 U.S. 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.
The feature set tables have been removed from the Cisco IOS Release 12.3 release notes to improve the usability of the release notes documentation. The feature-to-image mapping that was provided by the feature set tables is available through Cisco Feature Navigator.
Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or by feature set (software image). Under the release section, you can compare Cisco IOS software releases side by side to display both the features unique to each software release and the features that the releases have in common.
Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

Cisco CVA120 Series
This section contains the following sections with information that is specific to the Cisco CVA120 series:
•
Introduction
The Cisco CVA120 series cable voice adapter gives residential subscribers high-speed Internet access. The cable voice adapter supports data traffic via a shared two-way cable system and IP backbone network. The cable voice adapter connects computers and other customer premises devices at a subscriber site to the service provider's cable, hybrid-fiber coax (HFC), and IP backbone network.
The Cisco CVA120 series of cable voice adapters are based on Data-over-Cable Service Interface Specifications (DOCSIS) and European DOCSIS (EuroDOCSIS) standards. Depending on the model, they interoperate with any bidirectional, DOCSIS-qualified or EuroDOCSIS-qualified Cable Modem Termination System (CMTS). The cable voice adapter ships from the Cisco factory with a Cisco IOS software image stored in nonvolatile Flash memory that supports DOCSIS-compliant and EuroDOCSIS-compliant bridging operations.
The cable voice adapter uses its cable interface to connect to the CMTS over the HFC cable system. A PC connects to the cable voice adapter through either the Ethernet interface or the Universal Serial Bus (USB) interface. The cable voice adapter then provides Internet access by forwarding traffic between the PC and the CMTS, creating a high-speed, permanent access to the Internet.
If supported by the service provider, the cable voice adapter can connect to multiple PCs by attaching a PC to each interface (Ethernet and USB). In addition, the cable voice adapter's Ethernet interface can connect to an Ethernet hub, and multiple computers can then be connected to the hub.
Note
In addition to providing DOCSIS and EuroDOCSIS connectivity, the cable voice adapter can optionally provide Voice over IP (VoIP) services, allowing subscribers to make telephone, modem, and fax calls over TCP/IP networks such as the Internet. These calls can be made to other VoIP devices, or to telephone, modem, or fax devices on the regular telephone network (the public switched telephone network, commonly known as PSTN).
The cable voice adapter can also function as an advanced router, providing WAN data connectivity in a variety of configurations.
Cisco CVA122 Cable Voice Adapter
The Cisco CVA122 cable voice adapter features one F-connector interface to the cable system, one RJ-45 (10BASE-T Ethernet) hub port, one USB device port, and two RJ-11 analog voice ports. The USB interface enables the cable voice adapter to connect to a PC with a USB interface, without requiring the user to open the unit and install an Ethernet network interface card (NIC). If supported by the PC and service provider, PCs can be connected to the cable voice adapter using both the Ethernet and USB interfaces.
The Cisco CVA122 cable voice adapter supports the DOCSIS standard, which was developed with service providers to ensure that any DOCSIS-certified cable modem can interoperate with any bidirectional, DOCSIS-qualified CMTS. The DOCSIS standard supports the North American National Television Systems Committee (NTSC) channel plan, with 6-MHz channel widths, a downstream range of 88 to 860 MHz, and an upstream range of 5 to 42 MHz.
The feature sets available in Cisco IOS Release 12.3 for the Cisco CVA122 cable voice adapter include the DOCSIS IP Bridging, IP Routing, and Easy IP feature sets.
Cisco CVA122E Cable Voice Adapter
The Cisco CVA122E cable voice adapter features one F-connector interface to the cable system, one RJ-45 (10BASE-T Ethernet) hub port, one USB device port, and two RJ-11 analog voice ports. The USB interface enables the cable voice adapter to connect to a PC with a USB interface, without requiring the user to open the unit and install an Ethernet network interface card (NIC). If supported by the PC and service provider, PCs can be connected to the cable voice adapter using both the Ethernet and USB interfaces.
The Cisco CVA122E cable voice adapter supports the EuroDOCSIS standard, which is almost identical to the DOCSIS standard, except that it supports the European Phase Alternating Line (PAL) and Systeme Electronique Couleur Avec Memoire (SECAM) channel plans, with 8-MHz channel widths, a downstream range of 88 to 860 MHz, and an upstream range of 5 to 65 MHz.
The feature sets available in Cisco IOS Release 12.3 for the Cisco CVA122E cable voice adapter include the DOCSIS IP Bridging, IP Routing, and Easy IP feature sets.
Memory Recommendations

Additional Notes for the CVA120 Series
This section contains important information about using the Cisco CVA120 series with Cisco IOS Release 12.3 software.
Detecting Carrier Sense Errors
The Cisco CVA122 cable voice adapter cannot detect carrier sense errors on the four Ethernet ports that connect the router to the subscriber's local area network. This is because the four Ethernet ports are provided by an internal hub that always provides a carrier sense signal to the Cisco IOS software, even if no Ethernet devices are connected to the external ports.
In particular, this means that the dot3StatsCarrierSenseErrors attribute in ETHERLIKE-MIB (RFC 2665) will never indicate any drops in carrier of the Ethernet interface.
Cisco Voice Gateway 200
This section contains the following sections with information that is specific to the Cisco Voice Gateway 200 (Cisco VG200):
•
Introduction
Note
The Cisco VG200 allows customers to connect Cisco IP telephony solution products such as IP phones to the PSTN or to a PBX. Analog telephones or fax machines can also be connected. The compact Cisco VG200 chassis with a single 10/100 BASE-T Ethernet port contains a network module (NM), which provides digital signal processor (DSP) resources, and voice interface cards (VICs) and/or voice WAN interface cards (VWICs), which are used to provide the physical voice interfaces.
A typical configuration includes a NM-2V network module and two VICs. These VICs can be any combination of foreign exchange station (FXS), foreign exchange office (FXO), ear and mouth (E&M), or Basic Rate Interface (BRI) (both user and network sides), for a total of four channels.
In another common configuration of the Cisco VG200, the digital T1/E1 packet voice trunk network module is used. The module can support up to 60 voice channels (two E1 interfaces in a single network module). this packet voice trunk module supports both on- and off-premise connections to PBXs and PSTNs.
The NM-HDV card can be used to support digital voice termination, as well as transcoding and conferencing services.

Additional Notes for the Cisco Voice Gateway 200
This section contains important information about using the Cisco Voice Gateway 200 with Cisco IOS Release 12.3 software.
Handling Incoming Caller ID Digits on an E&M Port
When an H.323 T1-CAS E&M port on the Cisco VG200 is used, incoming caller ID digits may not be processed correctly by Cisco IP interactive voice response (IVR) applications, such as Cisco IP Auto-Attendant.
Depending on the T1-CAS line provisioning, incoming dialed number identification service (DNIS) digits received by the Cisco VG200 after its first wink to the central office (CO) are treated as user-entered digits and are sent to the remote endpoint as out-of-band dual tone multifrequency (DTMF) digits. If the remote endpoint is a Cisco IP IVR application, the out-of-band digits will be interpreted as a user entry and will change the application response. There are two ways to handle this situation:
•
•
Managing Input Gain for Cisco IP Voice Applications
When using the FXO ports on a Cisco VG200, set the input gain to a value greater than 10 to achieve adequate audio quality for use with Cisco IP voice applications or the Cisco IP Phone 7960. Enter the following series of commands from the Cisco IOS command line to set the correct value for input gain:
vg200# configure terminalvg200(config)# voice-port slot-number/port input gain valuePermitted entries for <value> are from -6 to 14. Gain values higher than 12 may cause DTMF recognition difficulties.
Enabling DTMF Relay with MGCP
Ensure that you use the following Media Gateway Control Protocol (MGCP) configuration command for enabling DTMF relay. If this command is not configured, DTMF tones will be not be regenerated correctly on the remote endpoint. The required command is as follows:
Router(config)# mgcp dtmf-relay codec all mode out-of-band
For further information about configuring MGCP, refer to the Software Configuration Guide for the Cisco VG200.

caller-id Command
When the caller-id command (which appears under "dial-peer" in the configuration commands) is used, the default setting is "off" for Japan and "on" for the United States. This command was introduced in Cisco IOS Release 12.1(2)XF.
DHCP Client Support
To configure the router for Dynamic Host Configuration Protocol (DHCP) client support, perform the following steps:
Step 1
Specifying the value client-id ethernet0 causes the MAC address of the Ethernet interface to be used as the client ID when the DHCP request is sent. Otherwise, the MAC address of the BVI is used as the client ID.

Delete files in the router Flash memory before attempting to download new images.
Caution
Flash Memory
Cisco 800 series routers use 4 MB of Flash memory for storing internal information such as the ROM monitor. Only the remainder of the Flash memory is available for storing Cisco IOS images and is displayed by using the show flash command. For example, if the router reports 8 MB of Flash, the actual amount of onboard Flash memory is 12 MB, even though only 8 MB are displayed and available for Cisco IOS image storage.
Multilink PPP and Interleaving
Multilink PPP fragments large data packets to allow small voice packets to be interleaved between them. However, apart from FIFO queueing, no other kind of output queueing mechanisms are currently supported with PPP over ATM. Consequently, when multilink PPP is configured on the Cisco 800 series routers, large packets are fragmented, but small voice packets are not interleaved between them.
NAT Support for H.323 Signaling
NAT does not support alerting H.225 messages; therefore, NAT communication cannot be established between router endpoints. NAT support for H.323 signaling is limited to the application NetMeeting.
PPP over AAL5SNAP Encapsulation Support
PPP over AAL5SNAP encapsulation is currently not supported, although the context-sensitive help mentions that it can be configured.
Cisco 800 Series Router Clock—CSCdp09409
To run IP Security (IPSec) successfully, the Cisco 800 series router clock needs to be set accurately. Cisco 800 series router clocks are set and maintained using Simple Network Time Protocol (SNTP). For best results, set up a Network Time Protocol (NTP) server to periodically send time information messages to Cisco 800 series routers. See the SNTP configuration and command reference documentation for configuration instructions. If you do not have an NTP server, you must reset the Cisco 800 series router clock using the clock set command each time you restart the router.
Dial Peer Limitation
The isdn answer1 and isdn answer2 commands determine which called telephone numbers, for example, 555-0100 and 555-0199, a Cisco 800 series router can answer. Using these commands limits a router to using the two dial peers that contain the telephone numbers 555-0100 and 555-0199. (When not using these commands, a router can use up to six dial peers.)
A sample scenario in which the isdn answer1 and isdn answer2 commands are used is when a Cisco 801 or Cisco 803 router is connected with other ISDN devices to an ISDN SBus.
Excessive ISDN Line Activation
The following protocols send updates that can cause an ISDN line to be activated excessively, thereby increasing your monthly ISDN line cost:
•
•
•
•
•
For information on preventing this situation, refer to the Cisco 800 Series Routers Software Configuration Guide. This guide contains information on setting up extended access lists to prevent IP, UDP, IPX, and SNTP updates from activating the ISDN line. For CDP, ensure that you enter the no cdp enable command to disable CDP.
Hanging During Boot
If an illegal console configuration is issued to the router, the console will fail the POST test during boot and cause the router to pause indefinitely. There is no way to recover a unit in this state except by pulling the soldered boot Flash and reburning the boot ROM.
This problem has been resolved in TinyROM version 1.0(3), a downloadable ROM upgrade available from Cisco.com. Please contact Cisco to upgrade to this version or later, and prevent this problem from occurring.
Phone Mate Answering Machine Model 9200
A Phone Mate answering machine model 9200 failed to recognize the ringing signal sent by AMD R79 ringing SLIC. This failure was confirmed by testing against Phone Mate model 3750 and the newer model 9300.
B-Channel Activation
When a call comes in, a B channel is activated. If the amount of traffic on the B channel exceeds a threshold, the other B channel is activated. If the amount of traffic falls below the threshold, one of the B channels is deactivated. The B channel that is initially activated when the call comes in is not necessarily B1, nor is the B channel that is deactivated when the traffic level lessens necessarily B2.
Cisco uBR905 and Cisco uBR925 Series Cable Access Routers
This section contains the following sections with information that is specific to the Cisco uBR905 and Cisco uBR925 cable access routers:
•
Introduction
The DOCSIS-based Cisco uBR905 cable access router gives small office, home office (SOHO) and branch office subscribers high-speed Internet or intranet access. The Cisco uBR905 cable access router supports data traffic via a shared two-way cable system and IP backbone network. The Cisco uBR905 cable access router connects computers and other customer premises devices at a subscriber site to the service provider cable, hybrid fiber-coaxial (HFC), and IP backbone network.
The Cisco uBR905 cable access router is based on Data-over-Cable Service Interface Specifications (DOCSIS) and interoperates with any bidirectional, DOCSIS-qualified cable modem termination system (CMTS). The Cisco uBR905 cable access router ships from the Cisco factory with a Cisco IOS software image stored in nonvolatile Flash memory that supports DOCSIS-compliant bridging data operations. The Cisco uBR905 cable access router functions as a cable modem at the subscriber site to convey data communications on the cable television system.
Based on the feature licenses your company purchased, other Cisco IOS images can be downloaded from Cisco.com. Special operating modes, based on your service offering and the practices in place for your network, can be supported for the Cisco uBR905 router, based on the available images in Cisco IOS Release 12.3. The Cisco uBR905 cable access router can also function as an advanced router, providing WAN data connectivity in a variety of configurations.
Note
The Cisco uBR905 cable access router features a single F-connector interface to the cable system, four RJ-45 (10BASE-T Ethernet) hub ports, and one RJ-45 console port to connect to a laptop computer/console terminal for local Cisco IOS configuration. The Cisco uBR905 cable access router also provides an onboard IP Security (IPSec) hardware accelerator, which provides high-performance encryption that is substantially faster than software-based encryption.
Memory Recommendations
For memory recommendations for the Cisco uBR905 and Cisco uBR925 cable access routers in Cisco IOS Release 12.3, refer to the "Memory Recommendations" section.
Headend Interoperability
DOCSIS Concatenation
If DOCSIS concatenation with a 16-QAM (quadrature amplitude modulation) symbol rate is used, the CMTS must be configured for Unique Word 16 in the preamble for both short and long data burst profiles. On the Cisco uBR7200 series universal broadband routers, use the cable modulation-profile global configuration command and specify "uw16" for both the long and short modulation profiles.
DOCSIS 1.0+ Extensions
The Cisco uBR905 supports the DOCSIS 1.0+ Extensions, which include dynamic multi-SID assignment and concatenation. To configure the Cisco uBR905 cable access router to support multiple classes of service, use either the Cisco Subscriber Registration Center (CSRC) tool or the configuration file editor of your choice. DOCSIS configuration files can contain multiple classes of service (CoS) to support voice and other real-time traffic. The first CoS is used for data (and voice if no other CoS is defined), and up to three additional classes of service can be defined to give higher priority for voice and other real-time traffic.
IPSec Encryption Support
To use IPSec encryption, the Cisco uBR905 cable access router and the destination endpoint must support IPSec encryption and be configured for the same encryption policy. The endpoint is typically an IPSec gateway such as a peer router, Cisco PIX Firewall, or other device that can be configured for IPSec. (The CMTS need not support IPSec encryption unless it is desired that the CMTS act as an IPSec gateway.)

Limitations and Restrictions
Cisco IOS Release 12.3 for the Cisco uBR905 cable access router contains the following limitations and restrictions.
Bridging Support
The Cisco uBR905 cable access router interoperates with DOCSIS cable networks.
DOCSIS CLI Commands Are Removed
To comply with DOCSIS requirements that restrict access to commands that change DOCSIS parameters, Cisco IOS Release 12.3 removes a number of commands from the command-line interface (CLI). The following commands and their no form are reserved exclusively for DOCSIS use:
•
•
•
•
•
Cisco IOS Configuration File Download
The DOCSIS configuration file can contain an optional Vendor-Specific Information Field (VSIF) that instructs the Cisco uBR905 or Cisco uBR925 cable access router to download a Cisco IOS configuration file before coming online.
In Cisco IOS Release 12.3(1), if the DOCSIS configuration file specifies a download of a Cisco IOS configuration file, that download is required—if the download of the Cisco IOS configuration file fails for any reason, the Cisco uBR905 or Cisco uBR925 cable access router will log a "CMAC_LOG_CONFIG_FILE_CISCO_BAD_TYPE" error message.
Detecting Carrier Sense Errors
The Cisco uBR905 and Cisco uBR925 cable access routers cannot detect carrier sense errors on the four Ethernet ports that connect the router to the subscriber's local area network. This is because the four Ethernet ports are provided by an internal hub that always provides a carrier sense signal to the Cisco IOS software, even if no Ethernet devices are connected to the external ports.
In particular, this means that the dot3StatsCarrierSenseErrors attribute in ETHERLIKE-MIB (RFC 2665) will never indicate any drops in carrier of the Ethernet interface.
IP Address Negotiation
The DOCSIS specifications require that a cable modem obtain its IP address at power-on or reset from a DHCP server that is available through the cable interface. For this reason, the cable access router defaults to a configuration that uses the ip address docsis command for the cable interface. It is not possible to override this setting by specifying a static IP address; to assign a static IP address to the Cisco uBR905 router, configure the DHCP server so that it assigns the desired IP address on the basis of the unit MAC address.
Upgrading Software Images Using BPI
To enable BPI encryption, the cable access router must use a Cisco IOS image that supports BPI encryption. If the current software image of the router does not support BPI encryption (or if the current software image is corrupted), you must disable BPI encryption in the DOCSIS configuration file and reset the router before you will be able to download a new software image.
Using Access Lists 170, 171, and 172
Access lists 170, 171, and 172 are reserved for DOCSIS use and should never be configured manually on the Cisco uBR905 or Cisco uBR925 cable access router. Use the other access lists between 100 through 199 instead.
Using Multiple PCs with the Cisco uBR905 or Cisco uBR925 Cable Access Router
The "MAX CPE" parameter in a Cisco uBR905 or Cisco uBR925 cable access router DOCSIS configuration file determines how many PCs (or other CPE devices) are supported by the Cisco uBR905 cable access router. The default value for the "MAX CPE" parameter is 1, which means only one PC can be connected to the Cisco uBR905 cable access router.
The DOCSIS 1.0 specification states that a CMTS cannot age-out MAC addresses for CPE devices, so the first PC that is connected to the Cisco uBR905 or Cisco uBR925 cable access router is normally the only one that the CMTS recognizes as valid. If a subscriber replaces an existing PC or changes its network interface card (NIC) to one that has a different MAC address, the CMTS will refuse to let the PC come online because the maximum number of CPE devices specified by the "MAX CPE" parameter would be exceeded. The CMTS will also refuse to let the PC come online if a user decides to move a PC from one Cisco uBR905 or Cisco uBR925 router to another.
To allow a subscriber to replace an existing PC or NIC, the following workarounds are possible:
•
•
Using the Reset Switch
The reset switch on the back panel of the Cisco uBR905 or Cisco uBR925 cable access router is recessed to prevent accidental resets of the router. To depress the switch, use a blunt object, such as a pen or pencil point; do not use a sharp object, such as a knife or awl, because sharp objects could damage the switch and the circuitry of the router.
Additional Notes for the Cisco uBR905 Cable Access Router
This section contains important information about using the Cisco uBR905 or Cisco uBR925 cable access router with Cisco IOS Release 12.3 software.
Configuring the CMTS Cable Interface When in Routing Mode
If you have configured a Cisco uBR905 or Cisco uBR925 cable access router for routing mode and are also using the cable-modem dhcp-proxy nat command on the router, you must configure the corresponding cable interface on the Cisco CMTS using the cable dhcp-giaddr policy command.
CPE Device Filtering
In Cisco IOS Release 12.1(3a)XL1 and later releases, the "docsDevCpeIpMax" attribute defaults to -1 instead of the default of 1, which was used in previous releases. This attribute controls the maximum number of CPE devices that can pass traffic through the router from its Ethernet interface as follows:
•
•
•
CPE IP address filtering is done as part of the following process:
1.
2.
3.
4.
See the DOCS-CABLE-DEVICE-MIB.my MIB for more information on the attributes and tables listed.
Disabling the Finger Server
By default, the Cisco uBR900 series cable access router enables its onboard TCP/IP "finger" server to allow remote users to query the number and identities of any users that are logged in to the router. Unless your network operations center (NOC) requires this service, it should be disabled to prevent denial of service attacks that access the well-known port (TCP port 79) of the finger server. To disable the finger server, include the no service finger command in the Cisco IOS configuration file that the router downloads at initial power-on.
Supported MIBs
The Cisco uBR905 cable access router supports the following categories of MIBs:
•
•
•
•
•
•
Cable Device MIBs
The Cisco uBR905 cable access router supports the Cable Device MIB, which is defined by RFC 2669 and describes DOCSIS-compliant cable modems and CMTS. The Cable Device MIB records statistics related to the configuration and status of the cable modem. Statistics include an events log and device status. The following list details the components of the Cable Device MIB:
•
•
•
•
•
•
The Cable Device MIB is very similar to the Radio Frequency Interface (RFI) MIB in that both allow access to statistics; they are different in that the Cable Device MIB reports statistics on the cable modem, and the RFI MIB reports statistics on the radio frequency transmissions over the cable television line.
Cisco Standard MIBs
The Cisco uBR905 cable access router supports the Cisco Standard MIBs, which consist of the following components:
•
•
•
•
•
•
Note
Radio Frequency Interface MIBs
The Cisco uBR905 cable access router supports the Radio Frequency Interface (RFI) MIB. The RFI MIB module is defined in RFC 2670 and describes DOCSIS-compliant radio frequency interfaces in cable modems and CMTS. On the cable modem, RFI MIB entries provide the following features:
•
•
•
•
•
The RFI MIB includes tables that describe both the CMTS and the cable modem side of the cable interface. All cable modem tables are implemented.
With IPSec, data can be sent across a public network without fear of observation, modification, or spoofing. IPSec enables applications such as VPNs, extranets, and remote user access.
IPSec services are similar to those provided by Cisco Encryption Technology, a proprietary Cisco security solution. However, IPSec provides a more robust security solution and is standards based.
Cable-Specific MIBs
Table 6 shows the cable-specific MIBs that are supported on the Cisco uBR905 cable access router. This table also provides a brief description of each of the MIB contents and the Cisco IOS software release in which the MIB was initially functional—earlier releases might have had unsupported prototype versions of the MIB; later releases might have added new attributes and functionality.

Note
Deprecated MIBs
A number of Cisco-provided MIBs have been replaced with more scalable, standardized MIBs; these replaced MIBs have filenames that start with "OLD" and first appeared in Cisco IOS Release 10.2. The functionality of these MIBs has already been incorporated into replacement MIBs, but the old MIBs are still present to support existing Cisco IOS products or network management system (NMS) applications. However, because the deprecated MIBs will be removed from support, you should update your network management applications and scripts to refer to the table names and attributes that are found in the replacement MIBs.
Table 7 shows the deprecated MIBs and their replacements. In most cases, SNMPv1 and SNMPv2 replacements are available, but some MIBs are available in only one version. A few of the deprecated MIBs do not have replacement MIBs; support for these MIBs will be discontinued in a future release of Cisco IOS software.

Additional Notes for the Cisco 1400 Series Routers
This section contains important information about using the Cisco 1400 series routers with Cisco IOS Release 12.3 software.
Multipartition Flash Default
When a multipartition Flash memory card is used, the various Flash partitions are referred to as "flash:1:", "flash:2:", and so on. If you specify only "flash" in a multipartition Flash, the parser assumes "flash:1:". For example, if you enter the show flash all command, the parser defaults to "show flash:1: all" and only the Flash information for the first partition displays. To see information for all Flash memory partitions, enter the show flash ? command. This information will list all of the valid partitions. Then enter the show flash:xx: all command on each valid partition.
Traffic Shaping
On the ATM25 interface of the Cisco 1400 series, there are two types of traffic shaping: hardware-based and software-based. Hardware-based traffic shaping is provided by the ATM SAR chip and is enabled on a per-PVC basis by one of the following Cisco IOS PVC configuration commands:
•
•
•
The SAR chip has "rate counters" that control the rate at which the current buffer up for segmentation will be sent. Ideally, the SAR chip could be programmed with values for all of the command parameters shown. Unfortunately, it has only the rate counters, which specify a divisor of the basic line rate of 25 Mbps and which set the maximum transmission rate (peak cell rate) for the channel. Note that with the ubr and ubr+ commands, the rate counter for the PVC is obtained from the peak-cell-rate parameter. With the vbr-nrt command, the rate counter is obtained from the sustainable-cell-rate parameter. Although the minimum-guaranteed-cell-rate parameter in the ubr+ command and the peak-cell-rate parameter in the vbr-nrt command can be specified by the user, they are ignored by the ATM25 driver.
Software-based traffic shaping is enabled on a per-interface basis via the traffic-shape interface configuration command. For performance reasons, and because for ATM interfaces you most likely want to do shaping on a per-PVC basis, the ATM driver does not support software-based traffic shaping while fast-switching. However, if fast switching is disabled and the traffic-shape interface configuration command is enabled, software traffic shaping will occur. (Refer to CSCdk28377 for more information.)

PPPoE provides service-provider DSL support. In service-provider DSL deployments, PPPoE facilitates consumer end adoption by leveraging Ethernet scale curves and by using an embedded base.
Caveat CSCdr91706 and Cisco IOS HTTP Vulnerability
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, 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 caveat CSCdr91706, affects virtually all mainstream Cisco routers and switches that run 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 releases. Customers are urged to upgrade to releases that are not vulnerable to this defect, as shown in detail below.
This vulnerability can be exploited only if the enable password is known or is not set.
You are strongly encouraged to read the complete advisory, which is available at the following URL:
http://www.cisco.com/warp/public/707/ioshttpserverquery-pub.shtml
Product Number Change
Beginning with Cisco IOS Release 12.0(7)XK, Cisco changed the product numbers used to order a specific Cisco IOS software image. In short, Cisco will remove the periods separating the release train, maintenance release, and build number. The following table provides some examples.
Deprecated MIBs
Older Cisco MIBs will be replaced in a future release. OLD-CISCO-* MIBs are currently migrated into more scalable MIBs—without affecting existing Cisco IOS products or network management system (NMS) applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 11.

Additional Notes for the Cisco 3600 Series Routers
This section contains important information about using the Cisco 3600 series routers with Cisco IOS Release 12.3 software.
CLI Command Added
The following command-line interface (CLI) command was added to Cisco IOS Release 12.2(2)T and is available in later versions:
ip qos dscp [0-63 | af11-af43 | cs1-cs7 | default | ef] [media | signaling]
This command replaces the ip precedence 0-7 VoIP dial-peer command. It implements RFC 2474, which specifies bits 0 to 5 of the IP ToS byte as the Differentiated Services Code Point (DSCP), with acceptable values ranging from 0 to 63. Traffic is treated in a unique manner according to the value of the DSCP. The expected treatment of this marked traffic is defined as a per-hop behavior (PHB). RFC 2474 also defines a set of PHBs to forward traffic at least as well as expected with the IP precedence bits (bits 0 to 2) of the old ToS byte marked. The DSCP values for these precedence compatible behaviors are xxx000, with the values of xxx ranging from 1 to 7 and the code points called Class Selector Code Points (cs1-cs7 in the command above). The default value is 000000 for media and signaling.
Two other RFCs have also defined PHBs. RFC 2597 defines the Assured Forwarding PHB Group. With Assured Forwarding (af11-af43), bits 0 to 2 represent the class of traffic stream, and bits 3 to 5 represent the drop priority of a traffic stream. RFC 2598 defines the Expedited Forwarding PHB Group and is intended to be used with media streams. Because it is possible that more PHB groups will be defined or that end users will want to experiment with a DSCP of their own, you may configure a DSCP with a value of 0 to 63 (rather than being limited to only the currently-defined PHBs).
The recommended values are ip qos dscp ef media and ip qos dscp af31 signaling.

Cisco MC3810 Multiservice Access Concentrators
This section contains the following sections with information that is specific to the Cisco MC3810 multiservice access concentrator:
•
Introduction
The Cisco MC3810 multiservice access concentrator is fully supported by Cisco IOS software for multiprotocol routing, bridging, and Systems Network Architecture (SNA). As part of an enterprise backbone or as a CPE device to serve provider-managed network services, the Cisco MC3810 reduces operating costs and complexity, and increases network throughput and performance.
The Cisco MC3810 provides a complete file system for software images, message files, and reports. The standard Flash memory size is 8 MB. A 16-MB upgrade option is available. The 16-MB version can hold two code images simultaneously for fail-safe upgrades.
Management and configuration of the Cisco MC3810 should be familiar to the Cisco IOS user and compatible with existing management systems. As such, it provides a superset of the Cisco command-line interface (CLI). The Cisco MC3810 can be managed by standard Cisco management platforms and facilities such as CiscoView and the native remote login facilities provided by Telnet and rlogin. Three types of configuration interfaces are provided as follows:
•
•
•
The HTTP-based interface allows configuration from any web browser such as Netscape Navigator or Microsoft Explorer. The Simple Network Management Protocol (SNMP) MIB allows management of the Cisco MC3810 from SNMP managers (for example, HP OpenView).
Cisco IOS Release 12.3 is the final software release that will support the Cisco MC3810. There will be no support for the Cisco MC3810 in Cisco IOS Release 12.3T.
Memory Recommendations
For memory recommendations for the Cisco MC3810 in Cisco IOS Release 12.3, refer to the "Memory Recommendations" section.
Supported Hardware
Cisco IOS Release 12.3 supports the Cisco MC3810 multiservice access concentrator. The Cisco MC3810 base chassis is a semifixed configuration router that can be customized for a specific application at the factory or in the field by a qualified technician. The base chassis includes the following components:
•
•
•
•
•
Cisco MC3810 series concentrators are supplied in various standard hardware configurations. These concentrators are equipped with different sets of functional modules to provide specific functional capability. Many configurations are possible, but they are all variations of the basic categories described in Table 16. Supported hardware is shown in Table 17. The chassis opening for any mounting area that is not equipped with a functional module is closed off with a removable cover plate.
For detailed descriptions of the new hardware features, see the "New and Changed Information" section on page 107.

You can derive the time-division multiplexing (TDM) clock reference on the AGM from one of seven sources. Each VIC slot that contains an E1 or T1 card has five free-running, onboard clock sources and two recovered clock sources.
The default reference is the onboard clock. You can use the frame-clock-select command to select one of the E1/T1 ports as the primary reference. You can also use the frame-clock-select command to select up to three prioritized backups, if the primary clock fails. If you switch over to a backup source, the system does not revert back to the status of the original clock source.
The frame-clock-select command has the following syntax:
[no] frame-clock-select priority E1/T1 slot/portThe clock source with priority one is the primary reference, and the clock source with priority four is the lowest priority backup.
The clock reference selection that uses the frame-clock-select command is independent from the clock reference selection on an E1/T1 controller. If you use the onboard clock as the reference, you can observe framing and CRC errors, which are caused by clock slips on E1/T1 interfaces.
Need to Support 56-kbps Operation for Slot 3 WIC
If you configure the MCC SI RAM for two entries, a defect on the 8260 Rev1A device on the AGM can cause data corruption (7 bits form the 56 kbps channel and 1 bit is discarded). Because there is not enough available space to use three SI RAM entries as a workaround, only 64kbps channels are supported. If you need to use 56kbps channels, use the WIC-56K4 WIC.
Cisco AS5300 Universal Access Servers
This section contains the following sections with information that is specific to the Cisco AS5300 universal access servers:
Introduction
The Cisco AS5300 is a versatile data communications platform that performs two functions in a single modular chassis, depending on the installed feature cards and Cisco IOS images:
•
•
The remote access server is intended for Internet service providers (ISPs), telecommunications carriers, and other service providers that offer managed Internet connections and medium to large sites that provide both digital and analog access to users on an enterprise network. By terminating both analog and digital calls on the same chassis simultaneously, the access server provides a clear, simple, and easy migration path from analog dial access services to digital dial access services.
The Cisco AS5300 voice gateway is a versatile data communications platform that provides the functions of an access server, router, and digital modem(s) in a single modular chassis. The Cisco AS5300 includes three feature card slots: one holds a T1/E1/PRI feature card, and the other two support modem feature cards or voice digital signal processor (DSP) feature cards. When equipped with modem cards, the Cisco AS5300 serves as a remote access concentrator for dial-up (modem or ISDN) Internet access. When equipped with voice feature cards and voice IOS, the Cisco AS5300 voice gateway serves as a Voice over IP (VoIP) gateway. By using one slot for modems and the other for voice DSPs, the Cisco AS5300 can serve in both capacities. Modem, voice, or fax calls are routed to the appropriate cards or resources via Dialed Number Identification Service (DNIS).

Cisco Signaling Link Terminals
This section contains the following sections with information that is specific to the Cisco Signaling Link Terminal:
Introduction
The Cisco Signaling Link Terminal (SLT) enables service providers to reliably transport Signaling System 7 (SS7) protocols across an IP network. The Cisco SLT uses the Cisco IOS SS7 Signaling Link Terminal feature set, providing reliable interoperability with the Cisco PGW 2200 Softswitch. The Cisco SLT is responsible for terminating the Message Transfer Part (MTP) 1 and MTP 2 layers of the SS7 protocol stack. Using the Cisco Reliable User Datagram Protocol (RUDP), the Cisco SLT backhauls, or transports, upper-layer SS7 protocols across an IP network to the Cisco PGW 2200 Softswitch.
In combination with this application-specific version of the Cisco IOS software, the Cisco SLT hardware component leverages the widely deployed Cisco 2600XM series multiservice access router. The Cisco 2600XM series, driven by a powerful RISC processor, provides the high performance required in complex networking infrastructures.
Note
When used for Signaling Link Terminal applications, the modular Cisco 2611XM and Cisco 2651XM dual-Ethernet port routers can be configured with dual serial and the multiflex interface cards. The E1 multiflex interface cards offer integrated DSUs, and the T1 multiflex interface cards offer integrated CSU/DSUs. For additional flexibility, the multiflex interface cards can also be ordered with a dual-port drop-and-insert capability. All of these interface cards are Field Replaceable Units (FRUs).
The Cisco SLT supports only the SS7 MTP 2 serial protocol. Therefore, the serial interfaces cannot be configured for other protocols such as HDLC, PPP, X.25, LAPB, and Frame Relay.
Memory Recommendations
For memory recommendations for the Cisco Signaling Link Terminal in Cisco IOS Release 12.3, refer to the "Memory Recommendations" section.
