New and Changed Information

The following sections list the new hardware and software features supported by the Cisco 1700 series for Release 12.1 T.

New Hardware Features in Release 12.1(3)XJ

The following new hardware enhancements are supported by the Cisco for Release 12.1(3)XJ and above. For more information about new hardware, see the "Platform-Specific Documents" section.

1-Port ADSL WAN Interface Card

The ADSL WAN interface card is a 1-port WAN interface card (WIC) for the Cisco 1700 series of modular access routers. The card provides asymmetric digital subscriber line (ADSL) high-speed digital data transfer between a single customer premises equipment (CPE) subscriber and the central office.

The ADSL WIC is compatible with the Alcatel Digital Subscriber Loop Access Multiplexer (DSLAM), the Cisco 6260 DSLAM with Flexi-line cards and the Cisco 6130 DSLAM with Flexi-line cards. It supports Asynchronous Transfer Mode (ATM) Adaptation Layer (AAL)5 (AAL5) and various classes of Quality of Service (QoS) for both voice and data service.

---

Note ADSL is a last-mile access technology, which has an asymmetrical data rate running over a single copper wire pair.

---

New Software Features in Release 12.1(3)XJ

The following new software enhancements are supported by the Cisco for Release 12.1(3)XJ and above. Release 12.1(3)XJ contains the following three new or modified Cisco IOS commands for configuring the ADSL WAN interface card:

•[no] dsl operating-mode { auto | ansi-dmt | itu-dmt }

•show dsl interface atm n

•show diag wic-slot-num { mem start_address end_address | log }

For details about these commands and ADSL WAN interface card configuration instructions, see following publications:

•1-Port ADSL WAN Interface Card online feature module documentation

•Configuring an ADSL WAN Interface Card on Cisco 1700 Series Routers 

•The "Configuring ATM" section of the Cisco IOS Wide-Area Networking Configuration Guide 

•The "ATM Commands" section of the Cisco IOS Wide-Area Networking Command Reference 

New Software Features in Release 12.1(1)

Important Notes

The following sections contain important notes about Cisco IOS Release 12.1 that can apply to the Cisco 1700 series. (Also, see the "Caveats" section.)

Cisco Express Forwarding

When installed in a Cisco 1720 or 1750 router, the Cisco Virtual Private Network (VPN) module does not support Cisco express forwarding (CEF).

Fan Operation in Cisco 1700 Series Routers

The fans in Cisco 1700 series routers stay off until thermally activated.

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 show flash ?. This will list all of the valid partitions. Then enter 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 12.1 T are also in Release 12.1(3)XJ. For information on caveats in Cisco IOS Release 12.1 T, refer to the Caveats for Cisco IOS Release 12.1 T document. For information on caveats in Cisco IOS Release 12.1, refer to the Caveats for Cisco IOS  Release 12.1 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.

Caveats for Release 12.1(3)XJ

This section describes possibly unexpected behavior by Release 12.1(3)XJ. Only severity 1 through 3 caveats are included.

LAN

•CSCds18508

On a Cisco 1700 series router, if you configure a secondary IP address on a Fast Ethernet or Bridge Group Virtual interface, reload the router, and enter the command show running-config, the secondary IP address does not appear. However, using the command show start correctly displays the secondary IP address. During bootup, the router displays the following error message:

"Secondary addresses not allowed with negotiated addresses." 

To work around this problem, reconfigure the secondary IP address after the router boots up.

SNMP/MIBs

•CSCdr72822

When using SNMP queries to retrieve information on the ADSL WIC, the serial number information and cardIfCardIndex is reported incorrectly by a Cisco 1700 series router.

•CSCdr76180

SNMP queries can retrieve AAL5 MIB information, which is configured under a sub-interface (such as [atm { 0 | 1 }]). However, SNMP queries to retrieve AAL5 MIB information do not return correct data from the main ATM interface (atm { 0 | 1 }). .

Voice

•CSCdr86655

The use of a hidden command is required to use an E&M interface with a PBX. If the remote end is also using a "y7" image, it must also be configured with the command voice rtp send-recv, regardless of which voice interface it uses.

WAN

•CSCdr72822

Cisco 1700 series routers incorrectly report serial number information when using SNMP queries to retrieve information on an ADSL-WIC.

•CSCdr83635

A Cisco 1700 series router cannot achieve Systems Network Architecture (SNA) connectivity with Qualified Logical Link Control (QLLC) over remote source-route bridging (RSRB) with local acknowledgement. There is no known workaround.

•CSCdr95335

Under some rare situations, an operational ADSL-WIC might generate the following debug message:

dslsar_tx_status_ind: freeing more buffers than exist.

•CSCdr98842

After reloading a Cisco 1700 series router with an ADSL-WIC, the router might intermittently generate the following error message:

ASSERTION FAILED: file ../les/if_dslsar_rcv.c, line 707

To work around this problem, reset the ATM interface(s) by using the command shutdown and then bring up the interface(s) again using the command no shutdown.

•CSCdr99127

If a Cisco 1700 series ATM interface with an ADSL-WIC is configured in an administratively- shutdown state in the startup configuration, following a system bootup the ADSL PHY/ADSL line still trains even though the interface remains down.

•CSCds01047

If you enter the command shutdown on an ATM interface and reload a Cisco 1700 series router, subsequently using the command show running-config does not display the ATM interface as shut down. However, using the command show start correctly displays the ATM interface as shut down.

•CSCds06523

Under certain undetermined conditions, an operational ADSL-WIC might occasionally produce the following debug message:

 atm_parse_packet(ATM0):Invalid VC(32776) received, type=xxxx.
