Release Notes for Cisco Broadband Operating System Release 2.2.0

January 14, 2000

These release notes discuss primary fixes, new features, important notes, open and resolved caveats, and the software upgrade process for the Cisco Broadband Operating System (CBOS) Release 2.2.0. Please refer to previous release notes for specific information concerning past releases.

For more detailed information about the features in these release notes, refer to the "Related Documentation" section. Information about electronic documentation can be found in the "Cisco Connection Online" section.

1. Contents

These release notes provide the following information:

2. Introduction

CBOS is the common operating system for most of Cisco's customer premises equipment (CPE) products. CBOS is modeled after Cisco's Internetworking Operating System (IOS) and features a similar command syntax and format. This operating system is bundled with the CPE products listed below and can also be downloaded from Cisco Connection Online.

The CBOS Release 2.2.0 supports the following Cisco ADSL CPE products:

The CBOS Release 2.2.0 also supports the following Cisco SDSL CPE products:


Note The Cisco 633 product does not use all of the feature set of CBOS. When a feature listed in Section 3 does not apply to the Cisco 633, the feature is marked accordingly.

3. New Features for the CBOS Release 2.2.0

The CBOS Software Release 2.2.0 supports the following new features:

3.1 PAT Enhancements


Note The following PAT and NAT features do not apply to the Cisco 633.

CBOS Release 2.2.0 adds Port Address Translation (PAT) enhancements to existing Network Address Translation (NAT) functionality. PAT and NAT enhancements are discussed in the following sections.

3.1.1 NAT support for the XDMCP protocol

CBOS Release 2.2 adds NAT support for (X-Display Manager Client Protocol (XDMCP) used for communications between X-Displays (clients) and X Display Managers (XDM). CBOS does this by translating the XDMCP protocol Request message, which embeds display hosts IP address, using NAT. Support for a single Connection Address only is provided in the request message.

The XDMCP protocol uses User Datagram Protocol (UDP) port 177 for messaging between display host and the server host and Transmission Control Protocol (TCP) port 6000, for displaying.

For inside-display-outside-server configurations, a static NAT entry for TCP port 6000 is required. In the case of an outside-display-inside-server configuration a static NAT entry for UDP port 177 is required.


Note Indirect Queries from Displays are not supported.

3.1.2 Support for Wildcard Static NAT entries

CBOS Release 2.2.0 adds support for wildcard static NAT entries. With this feature, you do not have to create one static entry per service port. You can direct all incoming connections to a single inside host irrespective of the port (e.g., File Transfer Protocol (FTP), Telnet, or web interface). This feature is supported in both PPP mode and RFC1483 mode.

NAT Commands Using Wildcards

Previous versions of CBOS required that you explicitly enter the port number and protocol name when adding a static NAT entry. CBOS Release 2.2.0 does not require you to do this. See the following example for more information.

To add a static NAT entry with wildcards for both the port number and protocol name, enter the following:

set nat entry add inside_ipaddress

To add a NAT entry with a wildcard protocol:

set nat entry add inside_ipaddress portnum

NAT Commands With No Changes

The following NAT commands have not changed:


Table 1: NAT Commands with No Changes
Command Description

set nat entry delete all

Deletes all NAT entries.

set nat entry delete inside inside_ip_address

Deletes all NAT entries that match the specified inside IP address.

set nat entry delete outside outside_ip_address

Deletes all NAT entries that match the specified outside IP address.

show nat

Displays all NAT entries, including static and wildcard Wildcard entries display as asterisks.

You can also override wildcard mapping with a specific mapping for a specific service. To direct different services to different hosts, you can specify a combination of specific NAT entries and wildcard NAT entries. NAT function first looks for a specific NAT entry that matches the port, protocol, and address and if one exists, NAT uses it. Otherwise, NAT uses the wildcard NAT entry.

NAT Commands With Changes

The following table shows the applicable changes in the NAT command syntax:


Table 2: NAT Commands with Changes
Old (Pre-2.2.0) Version of Command New (2.2. 0 and higher) Version of Command Description
set nat entry delete inside_ipaddress portnum outside_ipaddress portnum protocolname set nat entry delete inside_ip_address portnum protocolname

Both entries delete a specific static NAT entry.

set nat entry add inside_ipaddress portnum outside_ipaddress portnum protocolname set nat entry add inside_ipaddress portnum protocolname

Both entries add a specific static NAT entry.


Note CBOS 2.2.0 supports both versions of the preceding commands. However, Cisco recommends that you use the latest version.

3.1.3 Support for NAT Entries Using IPCP

This feature allows static NAT entries to automatically assume the Internet Protocol Control Protocol (IPCP) address. This means that you no longer have to specify the outside IP address, its port number or its protocol name. IPCP now assigns the outside IP address for translation in the case of PPP routing. In RFC1483 routing mode, the outside IP address has to be manually set.

3.1.4 Support for NAT with VIP Interfaces

CBOS Release 2.2.0 adds support for using NAT with Virtual Interfaces (VIPs) selectively. This feature allows DSL service providers to set up multiple subnets to the CPE and NAT only one of the subnets. This works in the following manner:

Since VIPs are virtual interfaces on top of ETH0 with the same MAC address, CBOS cannot differentiate ETH0 traffic from VIP traffic without explicitly looking at the IP addresses configured. See the following sections to see how NAT looks at the IP addresses to make this differentiation:

For data received on WAN0-0

If the destination IP address is the NAT inside global IP address, then NAT translates the address in an outside to inside direction. Otherwise, NAT does not translate the traffic.

For data received on ETH0 (including VIPs)

If the source IP address is part of ETH0 configured subnet and the transmit port is the WAN0-0 port, then NAT translates the address in an inside to outside direction. Otherwise, NAT does not translate the traffic.

When NAT is enabled, NAT translates only inside to outside traffic and outside to inside traffic. NAT treats traffic in the following manner:

3.1.5 Support for IGMP Proxy Support with NAT and PAT

CBOS Release 2.2.0 adds Internet Group Management Protocol (IGMP) proxy support with NAT and PAT. This support is mainly for IGMP messages and UDP data destined to multicast destinations. Applications such as IP/TV is be supported only in multicast (scheduled broadcasts) mode when PAT is enabled. Applications that employ unicast for session setup (signaling) and later use multicast for data will have to be handled individually and therefore may not work through PAT.

3.2 Support for OAM ping originating from the CPE

CBOS Release 2.2.0 adds support for end-to-end pings for Operations and Administrations Maintenance (OAM) loopback cells. For example:

ping wan0-0

Initiates end-to-end loopback OAM cell

The ping command reports OAM Loopback success or failure, but does not report any time based or other metrics.

3.3 Support for Error log enhancements

CBOS Release 2.2.0 supports the following error log enhancements:

  DDD:HH:MM:SS
  Where DDD is the number of days, HH is hours, MM is minutes and SS is seconds.

The following types of messages are supported:

3.4 Display for negotiated Ethernet speed


Note The following feature does not apply to the Cisco 633.

CBOS Release 2.2.0 displays the negotiated speed (10 or 100Mbps) and duplex setting of the Ethernet interface.

3.5 Support for Exec Login Null

If the Exec password is null, CBOS Release 2.2.0 refuses Telnet login and displays the message "Connection refused, password not set" or equivalent.

3.6 Support for In-band message reporting


Note The following feature does not apply to the Cisco 633. This feature also requires the Cisco 6100 Release 2.3.0.

CBOS Release 2.2.0 displays all Digital Off Hook (DOH) related in-band messages to the console.

3.7 CBOS modifications for DOH compatibility


Note The following feature does not apply to the Cisco 633.

CBOS Release 2.2.0 supports the following modifications to display DOH information:

3.8 Support for a DHCP Server Duplicate Address Timer


Note The following feature does not apply to the Cisco 633.

The DHCP Server Duplicate IP address timer is now programmable, with a default of once every five seconds. This parameter is a CBOS NVRAM parameter only.

3.9 Support for a DHCP Lease Enhancement


Note The following feature does not apply to the Cisco 633.

The DHCP server now immediately removes any leased addresses from its IP address table. Previous releases removed leased addresses after 180 seconds.

3.10 Support for CHAP


Note The following feature does not apply to the Cisco 633.

CBOS Release 2.2.0 supports the Challenge Handshake Authentication Protocol (CHAP). CHAP provides more secure password authentication than the Password Authentication Protocol(PAP). Also, CHAP/PAP negotiation is auto-detected.

3.11 Support for VC Priority Queuing

CBOS Release 2.2.0 supports priority queuing of Virtual Circuits (VCs) on a per VC basis. Priority queues allows you to prioritize one VC queue over another by provisioning separate High and Low priority queues. Per VC priority queuing is an important feature in order to prioritize voice and video packets over data.

3.12 TFTP Client support

CBOS Release 2.2.0 supports the Trivial File Transfer Protocol (TFTP) client, which is a key feature needed to support the emerging configuration-less CPE architecture. CPE can now request configuration files and software loads with the TFTP client support. Previous versions of CBOS supported TFTP Server functionality only.

3.13 Support for Reboot Timer

This feature allows you to set a timer for reboot at a specified interval, which prevents you from correcting the configuration locally.

3.14 Support for Expanded Exec Level Capability


Note The following feature does not apply to the Cisco 633.

For CBOS Release 2.2.0, the Exec level password rights allow the user to:

3.15 Support for SNMP community names


Note The following feature does not apply to the Cisco 633.

CBOS Release 2.2.0 now supports the following Simple Network Management Protocol (SNMP) community names:

In addition, CBOS Release 2.2.0 provides better authentication and access control by supporting a list of SNMP Managers (instead of just one). This allows the Agent (c67x) to send traps to multiple SNMP Mangers instead of one location. This allows for more secure SNMP transactions with multiple IP addresses, instead of the current one. Each manager supports a community name. Authentication failures to the Agent result in Authentication TRAP messages being sent to the list of Managers. Traps can be enabled or disabled on a per manager basis.

3.16 New Commands

The CBOS Release 2.2.0 supports the following new commands:

  Sets the DHCP server duplicate address checking timer.
  Sets PAP/CHAP on or sets no PPP authentication.
  Sets ATM prior queuing on or off.
  Sets the per-VC priority.
  Allows you to download a new tftp client. The mode variable is either "image" or "config", host is the IP address of TFTP server.
  Enables the shutdown reboot timer.

4. Important Notes

The following section describes information important to Release 2.2.0 of CBOS.

4.1 Upgrading to CBOS 2.2.0

The upgrade process is the same whether you use the Trivial File Transport Protocol (TFTP) or serially download the new image of the CBOS software. Once the new file is written to the flash, enter the reboot command from the CBOS command line to reset your system. The new image loads, decompresses two images, and programs the new images to the correct flash memory locations.

Caution Do not reset the system or halt its operation in any way during the upgrade process. Resetting while writing a new image to flash memory will corrupt the flash.

4.1.1 TFTP Download

See the following instructions to use TFTP to download a new software image.


Step 1   Login to the Cisco equipment using the Enable password.

Step 2   Enable TFTP on the Cisco equipment.

set tftp enabled

Step 3   Determine the equipment's IP address.

show int eth0

Step 4   From the DOS window or TFTP client, TFTP the image to the CPE. In a DOS window, the command is:

tftp -i <ip address of CPE> put <filename>

Step 5   Ensure that file downloaded correctly by issuing the following command:

show errors

You should see an "Image downloaded successfully" message.

Step 6   Reboot the CPE.

4.1.2 Serial Download

To serially download the image, enter the following settings through a serial console connected to your system:

Upgrading from CBOS Version 2.1.0

See the following procedure if you are updating from CBOS Version 2.1.0:


Step 1   Issue the following command from the CBOS command line:

set download code

The CPE begins downloading.

Step 2   Initiate a serial upload with the terminal program. In Hyperterminal, this is done by selecting Transfer-->Send--> then selecting the filename to send and XModem or Xmodem1K as the protocol.

Step 3   After the upload, the CPE automatically reboots and loads the new image.

The code sequence (shown below) is an example of what is displayed after a new image is serially downloaded; and the system is rebooted.

4.2 Bridging Mode Procedures


Note This section does not apply to the Cisco 633.

When the Cisco 67x operates in bridge mode, it behaves like a wire connecting a local PC directly to a service provider's network. Bridge data is encapsulated using the RFC1483 or Point-to-Point Protocol (PPP) (Bridging Control Protocol (BCP)) protocol to enable data transport. Because bridges operates at a Media Access Control (MAC) layer only, applications requiring IP communication, such as Telnet, Trivial File Transfer Protocol (TFTP), Remote Dial-In User Service (RADIUS), Syslog, Ping, and the web interface, are not available unless a management VC is configured.

Cisco currently supports a learning bridge mode. The virtual path identifier/virtual channel identifier (VPI/VCI) configuration of the Cisco 67x is unaffected by the operational mode (bridging versus routing) of the device.

Cisco also provides two methods of configuring and managing the bridged Cisco 67x, through in-band bridging management or through a separate management VC. The two methods cannot be used simultaneously. If a separate management VC is used, the Cisco 67x can only be managed remotely through WAN0-1 and not from the local network.

With rfc1483 management enabled, you can manage the router using telnet. The following commands are accessible through the managed bridge:

The following procedure shows how to set up the Cisco 67x for in-band bridging management.


Note You must be in the enable mode to do the procedure below. You must perform the procedure in the sequence as shown.

Step 1   To enable RFC1483 bridging, enter:
set bridging rfc1483 enabled

Step 2   To save your changes, enter:
write

Step 3   To reboot the device, enter:
reboot

Step 4   To enable in-band management of the bridge, enter:
set bridging management enabled

Step 5   To set the Ethernet interface, enter:
set int eth0 ip <ip address>

The IP address of the Ethernet port should be an IP address on the same network as that of the "far-end" station.

Step 6   To enable the Cisco 67x to direct management traffic to the far-end station, enter:
set route default wan0-0

Step 7   To set the default route, enter:
set route default ip <ip address>

The default IP address should the IP address of the far-end station that is used to telnet into the router.

Step 8   To save your changes enter:
write

Step 9   To enable your changes, reboot the router:
reboot

To manage the bridged Cisco 67x using a separate management VC, follow these steps:


Step 1   To disable in-band bridging management, enter:
set bridging management disabled

Step 2   To enable bridging PVC, enter:
set bridging PVC enabled

Step 3   To save your changes, enter:
write

Step 4   To reboot the device, enter:
reboot

After rebooting, the Cisco 67x will have two PVCs enabled. Wan0-0 is used strictly for bridged traffic, while WAN0-1 is used strictly for management traffic. Wan0-1 will be using RFC 1483 routing.

Step 5   Set an IP address on the Ethernet port that is on the same network as the far-end station out the WAN0-1 interface:
set int eth0 ip <ip address>

Step 6   Set the default route of the Cisco 67x to WAN0-1:
set route default wan0-1

For more information on using the set bridging command, see the Cisco Broadband Operating System User Guide.

The rules that govern bridging mode:

If you choose bridging as your connection mode, also see the following sections in the "Configuration Procedures" chapter of the your router's installation and operation guide:

4.3 RFC Routing Procedures


Note This section does not apply to the Cisco 633.

See the following sections for instructions on setting up your network to run the Routing Information Protocol (RIP) in RFC Routing mode.

4.3.1 Scenario #1: Assign the Cisco 67x to a subnet of the network of the terminating (Cisco 6400 or equivalent) equipment's ATM subinterface

Use the example values listed in the following table to configure the Cisco 67x accordingly:


Note The following values are examples only.


Table 3: Scenario #1--Sample Values for the Cisco 67x and the terminating equipment
Cisco 67x Terminating Equipment

ETH0: 192.168.18.1

atm0/0/0.40

mask:255.255.255.248

ip address 192.168.18.200 255.255.255.0

WAN0-0 destination: 0.0.0.0

rip network 192.168.18.0

With the example values above, the terminating equipment accepts RIP updates when they are sent from the 192.168.18.x network coming in on the terminating equipment's ATM subinterface (atm0/0/0.40).

The benefit of this method is that you do not have to issue additional commands to the Cisco 67x.

4.3.2 Scenario #2: Assign an IP address to the WAN0-0 interface on Cisco 67x that resides on the same network as the terminating equipment's ATM subinterface

Use the example values listed in the following table to configure the Cisco 67x accordingly:


Note The following values are examples only.


Table 4: Scenario #2--Sample Values for the Cisco 67x and the terminating equipment
Cisco 67x Terminating Equipment

ETH0: 192.168.18.100

atm0/0/0.40

netmask: 255.255.255.0

ip address 222.1.1.1 255.255.255.0

WAN0-0 destination: 222.1.1.2

rip network 222.1.1.0

If the Cisco 67x is in RFC mode and has an IP address assigned to the WAN0-0 interface, it uses that address as the source address when sending a RIP update out WAN0-0, instead of using the Ethernet interface (ETH0) address. Since the WAN0-0 destination on the Cisco 67x in this example is on the same subnet as the terminating equipment's ATM subinterface, the terminating equipment processes the RIP update it receives from the Cisco 67x.

The drawback of this scenario is that you must use an IP address on the Cisco 67x destination IP and add another configuration step. However, it is necessary due to the unnumbered nature of the Cisco 67x's DSL/ATM interface.

5. Limitations and Restrictions

The following list describes known issues and functionality details.

6. Open Caveats as of the CBOS Release 2.2.0

See the following sections for a list of open caveats for the Cisco 675/675e as of CBOS Release 2.2.0.

6.1 Open Caveats for the Cisco 633 as of Release 2.2.0

Table 5 lists open caveats for the Cisco 633 as of CBOS Release 2.2.0.


Table 5: Open Caveats for the Cisco 633 as CBOS Release 2.2.0
DDTS Entry Description

CSCdp10731

Serial management link not active until train with certain router serial card.

Impact: Serial data connection to 633 will not pass data until the SDSL line is trained, even on the management DLCI ser0-0. This problem occurs when connecting to routers using the PowerQUICC serial processor. The result is that the CPE can not be managed remotely via telnet on the LAN side until the SDSL line has trained.

Workarounds:

  • Use the RJ-45 serial management cable to manage the CPE locally.

  • Connect to the 633 serial data port with a router not using a PowerQUICC processor.

  • Use a terminal server and local RJ-45 serial management cable if remote telnet access is necessary before the line trains.

CSCdp11303

TFTP file put to TFTP server with port other than 69 fails.

Impact: If the user configures the TFTP server to listen to a port other than 69 the server will not correctly use that port, but instead use port 69.

Workaround: Use default port 69 for TFTP. This should not be a problem for most users.

CSCdp31461

Queue not maintaining bit rate.

Impact: High priority bitrate is not maintained on the second high priority queue when multiple high priority queues are configured.

Workaround: Only configure one VCC as being high priority if priority queuing is enabled.

CSCdp32415

Packet loss when train rates are different on same card.

Impact: When ports 1&3 or 2&4 are trained at different rates on the same card (i.e. 1168 on port 1 and 784 on port 3) you will experience packet loss. Although the rates can be different between 1&3 and 2&4 (i.e. 1168 on ports 1&3, and 784 on ports 2&4). This will only happen when the card is trained at different rates on the same card.

Workaround: Provision the card to have the same rates on ports 1&3 or ports 2&4.

For example:

Port 1: 1168 / 1168

Port 2: 784 / 784

Port 3: 1168 / 1168

Port 4: 784 / 784

CSCdp43028

Default powerscale value for version A.83 firmware is incorrect.

Workaround: none

CSCdp43068

256k rate shows up as 272k.

Impact: The 633/673 cannot be set for a rate of 256k.

Workaround: Set the rate of the 633/673 to be 272k.

6.2 Open Caveats for the Cisco 673 as of Release 2.2.0

Table 6 lists open caveats for the Cisco 673 as of CBOS Release 2.2.0.


Table 6: Open Caveats for the Cisco 673 as CBOS Release 2.2.0
DDTS Entry Description

CSCdp16512

User unable to add interface name as a gateway via web interface

Impact: User tries to add interface, such as the wan0-0, as a gateway via the web interface.

Workaround: Configure the interface as a gateway using the CLI

CSCdp17068

TFTP on alternate port not functioning.

Impact: The TFTP application will not function on alternate application ports.

Workaround: use the default port (69) for TFTP purposes.

CSCdp18490

DEBUG BERT command does not work.

Impact: User enters "debug bert" at enable level via CLI and it does not work.

Workaround: BERT is not implemented in 673. Don't use the debug bert command.

CSCdp23073

Using DHCP client with NAT and DHCP server gives incorrect results.

Imapct: User gets wrong address pool since the DHCP server giving the CPE an IP

address pool does not how NAT is setup.

Workaround: Do not use the DHCP client with NAT and DHCP server.

CSCdp23086

DHCP client not working over wan0-0.

Impact: The DHCP client feature does not take the DHCP address/mask offered to it by the server and use it as eth0 address/mask of CPE, when the server is out the wan0-0 port.

Workarounds:

  • Use a DHCP server that exists on the ethernet link of the 673.

  • Use RADIUS for dynamic address assignment.

  • Use IPCP pools for dynamic address assignment.

CSCdp24230

Syslog not reporting link state or ppp open states.

Impact: The syslog application does not report all pertinent data. (WAN port train, link quality, speed).

Workaround: Use the "set error module xxxxx" combined with: "set error debug enable". With "xxxxx" = the type of error reporting you would like to be sent to the syslog server. Some error modules, such as link quality and speed, will still not be reported correctly to a syslog server.

CSCdp31758

Bridging management should be disabled/not allowed in other modes.

Impact: Bridge management option available when not in bridging mode. Could cause connection/routing problems when enabled in routing mode.

Workaround: Do not enable bridge management when CPE is in PPP or RFC routing mode.

6.3 Open Caveats for the Cisco 675/675e as of Release 2.2.0

Table 7 lists open caveats for the Cisco 675/675e as of CBOS Release 2.2.0.


Table 7: Open Caveats for the Cisco 675/675e as CBOS Release 2.2.0
DDTS Entry Description

CSCdm08268

stats ip WAN0-0 does not display correct packet statistics.

Impact: Command "stats ip WAN0-0" always displays 0 stats.

Workaround: None.

CSCdm11515

NVRAM is not written when configuration is made on the Web.

Impact: Changes made on the web are only good until the cpe is rebooted.

Workaround: Use CLI interface to make permanent changes.

CSCdm36544

2.4:Web filter reports WAN0-1 as all interfaces

Impact: Web interface displays incorrectly.

Workaround: None.

CSCdm49278

OAM F5 Segment Cell sent as F5 End-to-End Cell

Impact: ping WAN0-x -s sends OAM F5 End-to-End cell instead of OAM F5 Segment cell.

Workaround: None at this time.

CSCdm50936

Telnet to c675 from Sun WS adds extra characters at password prompt.

Impact: Garbage characters are displayed at password prompt.

Workaround: User must backspace over garbage characters to enter password.

CSCdm55247

ATM OAM Pings do not appear to reflect end-to-end versus segment.

Impact: Pings may increment the wrong set of statistics and send out the wrong type of ping (end-to-end loopback versus segment.).

Workaround: None

CSCdm55340

IP Filters for deny all will take precedence over any other allow

Impact: Filters functionality is currently not working.

Workaround: None

CSCdm68034

Change start address for DHCP pool

Impact: DHCP gateway is first address in DHCP pool

Workaround: None. Feature request to be addressed next release.

CSCdm72771

Must write and reboot for snmp changes to take effect.

Impact: when configuring the 675 to properly respond to snmp queries, you must specify the remote snmp manager information such as ip address and read/write capability. These configuration changes don't take affect until write and reboot of 675.

Workaround: Must write and reboot 675 for config changes to take place.

CSCdm73505

Static routes not in routing table if gateway is ETH0 and ipcp address.

Impact: if you add a static route to a network on the ethernet side of a 675, you must specify the ETH0 address as the gateway. However, if the ETH0 address is obtained strictly via IPCP, the static route will not appear in the routing table.

Workarounds:

  • Manually assign the ETH0 address to the same ip as assigned by IPCP. This is less than ideal if the IPCP-ed address changes after every train by the 675.

  • Assign an address to a VIP interface on 675, and set up static route to use that address as the gateway. This is an easier workaround but may burn an ip address.
