cable-modem compliant bridge

no cable-modem compliant bridge

Syntax Description

This command has no arguments or keywords.

Defaults

DOCSIS-compliant bridging is enabled by default.

Command Modes

Cable interface configuration

Command History

Release	Modification
11.3(4)NA	This command was introduced for the Cisco uBR904 cable access router.
12.0(4)XI1	Support was added for the Cisco uBR924 cable access router.
12.1(1)XD	Support was added for the Cisco uBR914 cable DSU.
12.1(3)XL	Support was added for the Cisco uBR905 cable access router.

Usage Guidelines

It is normally not necessary to enter this command in data-over-cable bridging applications because DOCSIS-compliant bridging is enabled by default. However, to configure the router for full transparent bridging or for routing mode, use the no form of the command and then configure the router as desired using the appropriate CLI commands.

Examples

The following example shows how to enter the cable-modem compliant bridge command for a cable access router interface, starting from global configuration mode:

interface cable-modem 0
 cable-modem compliant bridge

no cable-modem downstream saved channel ds-frequency us-power

Note   Cisco IOS Release 12.1(2)T removed this command from the CLI for all platforms and reserved it for exclusive use by the DOCSIS provisioning process.

Syntax Description

ds-frequency	Downstream channel frequency in Hz, which can be from 91000000 to 860000000.
us-power	Upstream power level in decibels per millivolt (dBmV), which can be from 8 to 61.

Defaults

Enabled

Command History

Release	Modification
11.3(4)NA	This command was introduced for the Cisco uBR904 cable access router.
12.0(4)XI1	Support was added for the Cisco uBR924 cable access router.
12.1(2)T	This command was removed from the CLI for all platforms and reserved for exclusive use by the DOCSIS provisioning process.

Usage Guidelines

This command is auto-generated by the operation of the cable MAC layer process. The DOCSIS RFI specification requires that cable modems remember the downstream frequency and upstream power of the last successfully ranged session. These parameters are called up as the first downstream frequency and upstream power to use the next time the cable modem is booted. This operation dramatically speeds up the channel search.

Use the no cable-modem downstream saved channel ds-frequency us-power command to remove the saved frequency and power setting from the running configuration, which will be saved at the next initialization cycle.

Cisco recommends that this command NOT be used by end users of the Cisco uBR924 cable access router.

Examples

The following example shows how to remove the downstream frequency of 91000000 Hz and the upstream power level of 33 dBmV from the running configuration of a cable-modem interface, starting from global configuration mode:

interface cable-modem 0
 no cable-modem downstream saved channel 91000000 33

12.1(2)T	This command was removed from the CLI for all platforms and reserved for exclusive use by the DOCSIS provisioning process.

Usage Guidelines

This feature speeds up the frequency search performed by the cable access router. Normally it takes the cable access router about 30 to 50 seconds to sample 30 to 50 frequencies. The cable-modem fast-search command can reduce this search time. However, there might be some cases where this fast-search algorithm might not perform as well as the default algorithm. Trial and error is the only way to discover how well this feature works for your environment.

Examples

The following example shows how to enter the cable-modem fast-search command, beginning in global configuration mode:

interface cable-modem 0
 cable-modem fast-search

Cisco uBR924 cable access router

dtmf-relay [cisco-rtp] [h245-signal] [h245-alphanumeric]

no dtmf-relay

Syntax Description

cisco-rtp	Forwards DTMF tones using the Real-Time Transport Protocol (RTP) with a Cisco proprietary payload type. Note   RTP is a proprietary Cisco protocol that interoperates only between two Cisco access servers or routers running Cisco IOS images that support the RTP protocol. This typically requires Cisco IOS 12.0(5)T or later releases; see the router's release notes for complete information.
h245-alphanumeric	Forwards DTMF tones using the H.245 Alphanumeric User Input Indication method. This transmits each tone using a fixed duration of 500 milliseconds. Supports tones 0-9, *, #, and A-D.
h245-signal	Forwards DTMF tones using the H.245 Signal User Input Indication method. This transmits each tone using the original duration. Supports tones 0-9, *, #, and A-D.

Defaults

By default, DTMF tones are transmitted inband, as part of the voice traffic.

Command Modes

Dial-peer voice configuration mode.

Command History

Release	Modification
12.0(7)XR and 12.1(1)T	Support was added for the Cisco uBR924 cable access router.

Usage Guidelines

DTMF tones are generated when you press the keypad digits on a touch-tone phone. DTMF tones are most commonly used to dial calls, but they can also be used during a call to interact with an Interactive Voice Response (IVR) system, such as voicemail, automated banking services and so on. By default, DTMF tones are transmitted along with the regular voice traffic, but this can cause problems with some IVR systems.

In particular, IVR systems might not recognize DTMF tones when using highly compressed CODECs such as G.729a. These CODECs are highly optimized for voice frequencies, but they can distort DTMF tones, preventing IVR systems from recognizing the tones. To avoid this problem, use one or more of the following methods of transmitting DTMF tones in an out of band channel, separately from the voice traffic:

• Cisco RTP—This transmits the DTMF tones using a proprietary encoding that allows them to use the same RTP channel as the voice traffic. This method accurately transports DTMF tones but requires the use of Cisco gateways at both the originating and terminating endpoints of the H.323 call.

• H.245 Alphanumeric—This transmits DTMF tones through a separate H.245 signaling channel using H.245 User Input Indication messages. Tones are transmitted as alphanumeric digits with a fixed duration of 500 milliseconds. This method is required for all H.323v2 compliant systems.

• H.245 Signal—This transmits DTMF tones through a separate H.245 signaling channel using H.245 User Input Indication messages. This method preserves both the tone information and the original duration of the tone, which allows the caller to use services that require you to press a key for a particular length of time. For example, a popular calling card feature allows you to break out of an existing call by pressing the (#) key for more than two seconds and then make a second call without having to hang up in between.

You can enable more than one DTMF relay option for a particular dial peer, to support multiple destinations that might use different methods. If you enable more than one option, and if the peer is capable of receiving DTMF in more than one of these formats, the router selects the DTMF format with the highest priority:

1. Cisco RTP (highest priority)

2. H.245 Signal

3. H.245 Alphanumeric

4. None—DTMF is sent inband

Examples

The following example configures an outgoing dial peer so that DTMF tones to that destination are transmitted using the Cisco RTP protocol, if it is supported by the remote end; otherwise, the DTMF tones are transmitted using the H.245 signaling protocol.

ubr924(config)# dial-peer voice 100 voip 
ubr924(config-dial-peer)# destination-pattern 555-1212 

ubr924(config-dial-peer)# session target ipv4:192.168.100.110 
ubr924(config-dial-peer)# dtmf-relay cisco-rtp h245-signal 
ubr924(config-dial-peer)# exit 
ubr924(config)# 
 

The following example reconfigures the above dial peer and disables out of band DTMF signaling, so that the DTMF tones are sent inband, as part of the voice traffic:

ubr924(config)# dial-peer voice 100 voip 
ubr924(config-dial-peer)# no dtmf-relay 

ubr924(config-dial-peer)# exit 
ubr924(config)#

Cisco BR924 cable access router

h323-gateway voip bind srcaddr ip-address

no h323-gateway voip bind srcaddr

Syntax Description

ip-address

Specifies the IP address to be used for outgoing H.323 traffic, which includes H.225, H.245, and RAS messages. This typically is the IP address assigned to the Ethernet interface.

Defaults

No defaults assigned. By default, H.323 traffic is transmitted with the IP address assigned to the cable interface.

Command Modes

Interface configuration

Command History

Release	Modification
12.1(2)T	This command is introduced for the Cisco uBR924 cable access router.

Usage Guidelines

The h323-gateway voip bind command can be used with any interface, but it is primarily used with the Cisco uBR924 cable access router's Ethernet interface when configuring a virtual private network (VPN). In this configuration, the h323-gateway voip bind command configures the router so that VoIP traffic is sent using the IP address of the Ethernet interface (as opposed to the default behavior, which is to use the IP address of the default outgoing interface, which is the cable interface).

The h323-gateway voip bind command allows the enterprise network to maintain the H.323 gatekeeper and gateway in the enterprise network's address space. Without the h323-gateway voip bind command, outgoing voice traffic uses the IP address of the cable interface. This requires that the H.323 gatekeeper and gateway be maintained in the cable service provider's address space, which is not desirable if the enterprise needs to control the voice network and VPN configuration.

Note   The h323-gateway voip bind command can be used only when the Cisco uBR924 cable access router is operating in routing mode. This command has no effect when the router is operating in DOCSIS bridging mode.

Examples

The following example shows the Ethernet interface being configured with the IP address of 192.168.100.94, and that H.323 traffic will be transmitted using that IP address:

ubr924(config)# interface ethernet0 
ubr924(config-if)# ip address 192.168.100.94 255.255.255.0 
ubr924(config-if)# h323-gateway voip bind srcaddr 192.168.100.94 
ubr924(config-if)# 
 

The following example disables the H.323 binding, so that H.323 voice traffic is transmitted using the cable interface's IP address:

ubr924(config-if)# no h323-gateway voip bind srcaddr 
ubr924(config-if)# 

Related Commands

Command	Description
h323-gateway voip h323-id	Defines the H.323 name that identifies this Cisco uBR924 cable access router gateway to its associated gatekeeper.

ip address docsis

no ip address docsis

Syntax Description

There are no key words or arguments for this command.

Defaults

The cable access router uses the DHCP protocol, as required by the DOCSIS specification, to assign an IP address to its cable interface during system power-on.

Command Modes

Global configuration

Command History

Release	Modification
12.1(3)XL	This command is introduced for the Cisco uBR905 cable access router.
12.1(4)T	This command is introduced for the Cisco uBR924 cable access router and Cisco uBR914 cable DSU.

Usage Guidelines

The ip address docsis command configures the cable access router so that it obtains its IP address from a DHCP server at system power-on, which is a requirement for DOCSIS operation. Using the no ip address docsis command prevents the cable access router from operating in DOCSIS networks and should be used only in lab or test networks.

If no ip address command is specified, the cable access router defaults to configuring its cable interface with the ip address docsis command. To change this behavior, this command must be saved to the startup configuration, or it should be included as part of a Cisco IOS configuration file that is downloaded to the cable access router.

Note   Earlier Cisco IOS software releases for the cable access routers used either the ip address negotiated and ip address dhcp commands to specify that the cable interface should obtain its IP address from a DHCP server. These commands should not be used on cable access routers except that the ip address negotiated command can be used for the serial interface on the Cisco uBR914 cable DSU.

Examples

The following example configures the cable access router so that it obtains the IP address for its cable interface from a DHCP server:

ubr924(config)# ip address docsis 

ubr924(config)# 

Related Commands

Command	Description
cable dhcp-proxy	Specifies that DHCP should be used to assign an IP address to the Cisco uBR924 cable access router's Ethernet interface.
ip http negotiated	Specifies that a serial interface should use the PPP/IPCP (IP Control Protocol) to obtain an IP address at system power-on. (This command can be used only for the serial interface on the Cisco uBR914 cable DSU.)
ip http dhcp	Specifies the use of the DHCP protocol to obtain an IP address for any interface except the cable interface at system power-on.

ip http cable-monitor {basic | advance} [URL-IP-address URL-mask]

no ip http cable-monitor

Syntax Description

basic	Displays only the basic status and performance pages.
advance	Displays all status and diagnostic pages. Note   The Cable Monitor should not be used in advanced mode without first implementing a secure password strategy on the Cisco uBR924 cable access router. Enabling the Cable Monitor in advanced mode without setting an encrypted enabled password could provide information that would allow remote users to change the router's configuration.
URL-IP-address	Specifies the IP address for the Cable Monitor. This parameter, along with the URL-mask parameter, also defines the network that provides the IP address pool used by the temporary DHCP server when the cable interface goes down.
URL-mask	Specifies the subnet mask for the Cable Monitor. This parameter, along with the URL-IP-address parameter, also defines the network that provides the IP address pool used by the temporary DHCP server when the cable interface goes down.

Defaults

For URL-IP-address, 192.168.100.1

For URL-mask, 255.255.255.0

Command Modes

Global configuration

Command History

Release	Modification
12.1(1)T	This command is introduced for the Cisco uBR924 cable access router.
12.1(1)XD	Support was added for the Cisco uBR914 cable DSU.
12.1(3)XL	Support was added for the Cisco uBR905 cable access router.

Usage Guidelines

This command enables the Cable Monitor, an onboard web server that displays current status, troubleshooting, and performance information. The Cable Monitor can be accessed in two ways:

• When the Cisco uBR924 cable access router has established connectivity with the CMTS over the cable interface, a service technician can use a web browser to remotely access the router and display the desired information.

• When the cable network is not operational and the Cisco uBR924 cable access router is not online, the subscriber can access the tool with a PC connected to the router's Ethernet ports. Technicians can then prompt the user for the information they need to determine the source of the problem.

Enabling the Cable Monitor also enables the Cisco web server that is onboard the Cisco uBR924 cable access router (which is the equivalent to giving the ip http server command). However, when the Cable Monitor is enabled, all other access, including CLI access, to the onboard web server is automatically disabled.

Disabling the Cable Monitor using the no ip http cable-monitor command also automatically disables the Cisco web server (which is the equivalent of giving the no ip http server command).

The URL-IP-address and URL-mask parameters also specify that the class C private network 192.168.100.0 is the default address pool for the temporary DHCP server that activates when the cable interface goes down.

Examples

The following example enables the Cable Monitor for advanced mode, in which all status and diagnostic pages are displayed:

ubr924(config)# ip http cable-monitor advance 
ubr924(config)# 
 

The following example disables both the Cable Monitor and the Cisco web server, preventing all web server access to the Cisco uBR924 cable access router:

ubr924(config)# no ip http cable-monitor 
ubr924(config)# 

Related Commands

Command	Description
ip http port	Configures the TCP port number for the router's HTTP web server (the default is the well-known web server port of 80).
ip http server	Enables and disables the router's HTTP web server.

Note   The ip http command also supports two options, access-class and authentication, that should not be used when the Cable Monitor is enabled.

12.1(1)XD	Support was added for the Cisco uBR914 cable DSU.
12.1(3)XL	Support was added for the Cisco uBR905 cable access router.

Usage Guidelines

The show controllers cable-modem display begins with information from the first few registers of the Broadcom BCM3300 chip. Next is buffer information for the receive, receive MAC message, buffer descriptor, and packet descriptor rings. Then comes MIB statistics from the BCM3300 chip, DMA base registers to indicate where the rings start, global control and status information, and finally interrupts for the interrupt code.

When using this command, be sure to check the tx_count and the tx_head and tx_tail values for the buffer descriptor (TX BD) and packet descriptor (TX PD) rings. The tx_count should be greater than 0, and the tx_head and tx_tail values should not be equal. If these values do not change for a long period of time, it indicates there are packets stuck on the ring. This condition is often caused by the headend not giving grants.

12.1(3)XL	Support was added for the Cisco uBR905 cable access router.

Usage Guidelines

This command displays the details of the lookup table. The driver uses this table to convert the size of the packets that the Cisco uBR900 series wants to transmit into a bandwidth request to the CMTS in mini-slots. The contents of this table are affected by the upstream symbol rate that is negotiated between the CMTS and the cable access router.

Use this table to look up the packet size and determine how many mini-slots will be needed.

Examples

The mini-slot lookup table is displayed in the following example:

uBR924# show controllers cable-modem 0 lookup-table

Max Burst Size (minislots) = 0x6
Max Burst Length (bytes) = 0x4B

show controllers cable-modem number mac [errors | hardware | log | resets | state]

Syntax Description

number	Controller number inside the Cisco uBR900 series.
errors	(Optional) Displays a log of the error events that are reported to SNMP. This keyword enables you to look at the error events without accessing a MIB.
hardware	(Optional) Displays all MAC hardware registers.
log	(Optional) Displays a history of MAC log messages, up to 1023 entries. This is the same output that is displayed when using the debug cable-modem mac log command.
resets	(Optional) Extracts all of the reset causes out of the MAC log file and summarizes them in a mini report.
state	(Optional) Displays a summary of the MAC state.

Defaults

No default behavior or values.

Command Modes

Privileged EXEC

Command History

Release	Modification
11.3(4)NA	This command was introduced for the Cisco uBR904 cable access router.
12.0(4)XI1	Support was added for the Cisco uBR924 cable access router.
12.1(1)XD	Support was added for the Cisco uBR914 cable DSU.
12.1(3)XL	Support was added for the Cisco uBR905 cable access router.

Usage Guidelines

MAC log messages are written to a circular log file even when debugging is not turned on. These messages include timestamps, events, and information pertinent to these events. Use the show controllers cable-modem mac log command to view MAC log messages.

If the Cisco uBR900 series interface fails to come up or resets periodically, the MAC log will capture what happened. For example, if an address is not obtained from the DHCP server, an error is logged, initialization starts over, and the Cisco uBR900 series scans for a downstream frequency.

The most useful keywords for troubleshooting a Cisco uBR900 series are log, errors, and resets. See Examples 1 through 3.

Examples

The following sample display shows the MAC log file for a cable-modem interface that has successfully registered with the CMTS:

This output indicates that the Cisco uBR900 series acquired a downstream lock, successfully read a UCD, and successfully read a MAP. However, it was unable to communicate with the CMTS after ranging through all upstream transmit power levels. The Cisco uBR900 series tried to communicate with the CMTS 16 times without success, after which it reset the cable interface to try to find a better downstream frequency.

If the DHCP server could not be reached, the error would look like this in the MAC error display:

uBR924# show controllers cable-modem 0 mac errors

497989.804 D01.0  Discover sent no Offer received.  No available DHCP Server.
498024.046 D01.0  Discover sent no Offer received.  No available DHCP Server.
498058.284 D01.0  Discover sent no Offer received.  No available DHCP Server.
 

The show controllers cable-modem 0 mac resets command shows only the entries in the MAC log that begin with the field CMAC_LOG_RESET. Collectively presenting these fields provides you with a summary of the most recent reasons why the cable interface was reset.

Reset messages and brief explanations are included in the following examples; however, the reset messages do not commonly occur.

In the following example, the configuration file downloaded from the TFTP server could not be read. The file might not exist, or the file might have incorrect permissions.

The following example shows that the DHCP server could not be reached, or that it took too long to respond.

uBR924# show controllers cable-modem 0 mac resets

497989.804 CMAC_LOG_RESET_DHCP_WATCHDOG_EXPIRED

498058.284 CMAC_LOG_RESET_DHCP_WATCHDOG_EXPIRED        
 

The following example indicates that an event in the cable interface driver caused the interface to reset. This often occurs because a shut or clear command is currently being issued on the interface.

uBR924# show controllers cable-modem 0 mac resets

527986.444 CMAC_LOG_RESET_FROM_DRIVER                  
528302.042 CMAC_LOG_RESET_FROM_DRIVER

The following example display for the show controllers cable-modem 0 mac hardware command shows the detailed configuration of the interface driver and the MAC-layer hardware. The most interesting bit is the station address (hardware address). The MIB statistics reflect the MAC hardware counters for various events, but these counters are typically reset every few seconds, so their contents are not accurate in this display.

Below the MIB statistics in the show controllers cable-modem 0 mac hardware display, the BCM3300 registers section shows the DMA locations of the indicated processing routines of the Broadcom 3220 MAC chip within the Cisco uBR900 series.

The following show controllers cable-modem mac state command summarizes the state of the cable MAC layer and provides a list of downstream search frequency bands and the order in which they are searched. If the cable MAC layer is in the wait_for_link_up_state, the information shown in the display corresponds to the last time the interface was up. This allows useful information to be acquired from this display even though the modem has not been able to range and register. The normal operational state of the interface is the maintenance_state.

Syntax Description

number	Cable access router interface number.
accounting	(Optional) Displays the number of packets of each protocol type that has been sent through the cable access router interface.
counters	(Optional) Shows MIB counters on the cable interface.
crb	(Optional) Displays concurrent routing and bridging information for each interface that has been configured for routing or bridging. This option does not really apply to the Cisco uBR924; it is included because it is part of the subsystem that provides DOCSIS-compliant bridging. For more information, refer to the Bridging and IBM Networking Command Reference.
irb	(Optional) Displays integrated routing and bridging information for each interface that has been configured for routing or bridging. This option does not really apply to the Cisco uBR924; it is included because it is part of the subsystem that provides DOCSIS-compliant bridging. For more information, refer to the Bridging and IBM Networking Command Reference.
type	(Optional) Designed to display information about virtual LANs associated with the interface; however, this option is not supported on the Cisco uBR924.
