Appendix A: Cable Debug Commands
Revised: March 30, 2009, OL-15510-09
Additional debug commands are documented in the Cisco IOS Debug Command Reference, available on Cisco.com and the Documentation CD-ROM.
CautionThe debug commands are primarily intended for use in controlled test and troubleshooting situations with a limited volume of traffic. You should use caution when enabling debug messages because sending these messages to the console consumes system resources. Turning on too many types of debug messages can adversely affect the router's network performance, depending on what messages are being displayed and the type of traffic that is occurring.

debug cable classifiers
To display debugging messages for DOCSIS packet classifiers, use the debug cable classifiers command in privileged EXEC mode. To stop the display of debugging messages, use the no form of this command.
debug cable classifiers
no debug cable classifiers
Syntax Description
No additional keywords or syntax components are required.
Command Modes
Privileged EXEC mode
Command Default
DOCSIS packet classifier debugging is disabled by default.
Usage Guidelines
The debug cable classifiers command provides detailed information about the allocation, removal, activation and deactivation of packet classifiers. Generally, classifiers are used to identify IP packets by source port, destination port, or type of service. Classifiers are associated with service flows. For example, packet classifiers are dynamically created in most VOIP deployments and this debug command can be used to troubleshoot issues related to these classifiers as VOIP calls are created and torn down.
Because this command can produce a large volume of debug information, use this command only when you have also enabled debugging for a particular MAC address, set of MAC addresses, or a MAC address mask, using the debug cable mac-address command.
Examples
The following example enables classifier debugging for a single MAC address:
Router# debug cable mac-address 000a.73fa.dbaaRouter# debug cable classifiersCMTS Packet Classifiers debugging is onThe following enables classifier debugging for all MAC addresses with Organizational Unique Identifier (OUI) OUI 0013.11:

debug cable dhcp
To enable debugging of the Dynamic Host Configuration Protocol (DHCP) when it is used on the cable interface, use the debug cable dhcp command in privileged EXEC mode. To disable debugging output, use the no form of the command.
debug cable dhcp
no debug cable dhcp
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Command History
Usage Guidelines
The debug commands are primarily intended for use in controlled test and troubleshooting situations with a limited volume of traffic. In particular, avoid using the debug cable dhcp command on an interface with a significant number of CMs, because the resulting volume of debug output could impact system performance. Cisco recommends that when you use the debug cable dhcp command, you limit its output to a particular interface or CM, using the debug cable interface or debug cable mac-address commands.
Examples
The following shows typical debugging messages for the debug cable dhcp command for a particular cable modem that is acquiring a DHCP address:

debug cable l2-vpn
To display debugging messages for the Layer 2 mapping of cable modems to particular permanent virtual connections (PVC) or to a virtual local area network (VLAN), use the debug cable l2-vpn command in privileged EXEC mode. To stop the display of debugging messages, use the no form of this command.
debug cable l2-vpn [conditional]
no debug cable l2-vpn [conditional]
Note
Syntax Description
Command Default
No default behavior or values
Command Modes
Privileged EXEC
Command History
Usage Guidelines
The debug cable l2-vpn command displays status information for the mapping of cable modems to PVCs on an ATM interface (see the cable vc-map command) or to a VLAN on an Ethernet, Fast Ethernet, or Gigabit Ethernet interface (see the cable dot1q-vc-map command). The debug messages show when a cable modem is mapped to a PVC or VLAN, when the mapping is changed or removed, and when packets are sent and received over the mapping.
The conditional option displays information for each packet that is sent and received over an ATM PVC or VLAN mapping. Because this can produce a large volume of debug information, the conditional option can be used only when you have also enabled debugging for a particular interface or MAC address, using the debug cable interface and debug cable mac-address commands, respectively.
Examples
The following example shows typical output for the debug cable l2-vpn command when a cable modem is mapped to an ATM PVC:

debug cable mac-address
To display debug information for a specific CM, use the debug cable mac command in privileged EXEC mode. The no form of this command disables debugging output.
debug cable mac-address address [address-mask] [verbose]
no debug cable mac-address address [address-mask] [verbose]
Syntax Description
Command Modes

Command History
Usage Guidelines
You can repeat this command for other MAC addresses. Each time you specify a different MAC address, debugging is turned on for that particular MAC address.
If you enter two commands with the same MAC address, but with different values for the mask or verbose keywords, the router treats both commands as the same. In this case, the latest debugging information supersedes the previous debugging information.
Note
Examples
The following example demonstrates how to enable debugging for all traffic coming from cable interface 3/0 of CMs with the MAC address 00E0.1Exx.xxxx:

The service identifier (SID) value of 0 indicates that the modem has no assigned SID. The CM mac address is the MAC address of the modem's radio frequency (RF) interface, not its Ethernet interface. The Timing offset is a measure of the distance between the modem and the Cisco CMTS, expressed in 10.24 MHz clocks. This value is adjusted down to zero by the maintenance procedures. The first 16 bytes of the prepended header of the message are dumped in hexadecimal.

Examples
The following command enables debugging of upstream messages:
router# debug cable receiveCMTS debug Rx debugging is onThe debug cable receive command was disabled in Cisco IOS Release 12.1 T, 12.1 EC, and later releases, although it still appears in the CLI until Cisco IOS Release 12.1(11b)EC. To monitor the packets received from the CMs, use the debug ip packet command instead.
Because the debug ip packet command produces a large volume of messages, you must use it together with an access list to restrict the messages to a particular CM or CPE device to avoid affecting system performance. For example, the following commands would set up an access list that monitors all traffic being sent between the hosts with the two specified IP addresses:

Usage Guidelines
The debug cable registration command displays messages about the registration request and response messages sent and received by the CMTS when a CM initiates the DOCSIS registration process. To see the relevant messages, you must also enable debugging for a particular interface or CM using the debug cable interface or debug cable mac-address commands.
Examples
The following shows typical debugging output from a registration process:

Some CMs calculate the MD5 Message Integrity Check (MIC) over the length of the registration TLV parameters as well as the length of the shared secret itself, while other CMS calculate the MIC value only over the length of the registration TLV parameters. The Cisco CMTS attempts to verify the MIC and shared secret values using the first technique, and if that fails, the CMTS then uses the second technique to verify the CM.

debug cable tod
To display debugging for the local time-of-day (ToD) server on the Cisco CMTS, use the debug cable tod command in privileged EXEC mode. To disable debugging output, use the no form of this command.
debug cable tod
no debug cable tod
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Command History
11.3 NA
This command was introduced.
12.2(11)BC2
Support for this command was added to the Release 12.2 BC train.
Usage Guidelines
This command displays information about the operation of the ToD server that is onboard the Cisco CMTS. Before this command will display any output, you must also use the debug cable interface command to enable debugging operations on each interface that has CMs you wish to monitor.
Examples
The following example shows typical output for the debug cable tod command:
Router# debug cable interface c3/0Router# debug cable todTOD server debugging is onRouter#000104: Jun 8 05:48:08.783: tod: Received request from 10.1.1.27 (0001.9659.4411) on Cable3/0000105: Jun 8 05:48:15.015: tod: Received request from 10.1.1.32 (0030.96f9.65d9) on Cable3/0000106: Jun 8 05:48:16.363: tod: Received request from 10.3.3.10 (0001.9659.43fd) on Cable3/0000107: Jun 8 05:48:17.335: tod: Received request from 10.2.2.43 (0002.fdfa.0a35) on Cable3/0For telco-return CMs, the ToD server verifies that the IP address for the CM making the ToD request is on the correct cable interface, so as to prevent IP spoofing. If the IP address and interface do not match, the following message is printed:

Command History
12.0(7)XR
This command was introduced.
12.1(1)T, 12.1(2)EC1
This command was disabled.
12.1(11b)EC
This command was removed.
Examples
The following command enables debugging of messages that the CMTS transmits on the cable interface:
Router# debug cable transmitCMTS debug transmit debugging is onRouter#The debug cable transmit command was disabled in Cisco IOS Release 12.1 T, 12.1 EC, and later releases, although it still appears in the CLI until Cisco IOS Release 12.1(11b)EC. To monitor the packets transmitted by the CMs, use the debug ip packet command instead.
Because the debug ip packet command produces a large volume of messages, you must use it together with an access list to restrict the messages to a particular CM or CPE device to avoid affecting system performance. For example, the following commands would set up an access list that monitors all traffic being sent between the hosts with the two specified IP addresses:
router# configure terminalrouter(config)# access-list 150 permit ip host ip-address-1 host ip-address-2router(config)# access-list 150 permit ip host ip-address-2 host ip-address-1router(config)# exitrouter# debug ip packet 150 detailRelated Commands

12.2(33)SCA
This command was integrated into Cisco IOS Release 12.2(33)SCA.
Usage Guidelines
The debug cable wbcmts command is intended for use by Cisco technical support personnel.
Caution
If you specify debug cable wbcmts with no argument, generic wideband debugging messages are enabled.
Before issuing the debug cable wbcmts wcd command to display BDCD information, you must issue the debug cable interface command to enable debugging on the cable interface line card configured for DOCSIS 3.0 protocol operations. For example:
Router# debug cable interface Cable slot/subslot/portRouter# debug cable wbcmts wcdIn the preceding example, slot/subslot/port specifies a port on a cable interface line card that has been configured for DOCSIS 3.0 protocol operations with the modular-host subslot command. The line card cable interface for which you enable debug messages with debug cable interface is the first cable interface that is up. For example, if the line card configured for DOCSIS 3.0 protocol operations is located in slot 7/0, specify interface 7/0/1 if 7/0/0 is down and 7/0/1 is up.
For information on configuring a cable interface line card for DOCSIS 3.0 protocol operations, see the modular-host subslot command.

Usage Guidelines
Baseline privacy key management exchanges take place only when both the router and the CMTS are running code images that support baseline privacy, and the privacy class of service is enabled via the configuration file that is downloaded to the cable access router. Baseline privacy code images for the router contain k1, k8, or k9 in the code image name.
In Cisco IOS Release 12.0(5) and later releases, this command is available only under the direction of TAC or field service, and should be used only while debugging CM operation. Displaying debugging messages consumes system resources, and turning on too many messages could negatively affect system performance.

debug cable-modem bridge
no debug cable-modem bridge
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Command History
Usage Guidelines
When the interface is down, all bridge table entries learned on the Ethernet interface are set to discard because traffic is not bridged until the cable interface has completed initialization. After the interface (the line protocol) is completely up, bridge table entries learned on the Ethernet interface program the cable's MAC data filters. The cable MAC hardware filters out any received packets whose addresses are not in the filters. In this way, the cable interface only receives packets addressed to its own MAC address or an address it has learned on the Ethernet interface.
In Cisco IOS Release 12.0(5) and later releases, this command is available only under the direction of TAC or field service, and should be used only while debugging CM operation. Displaying debugging messages consumes system resources, and turning on too many messages could negatively affect system performance.
