Command History

Release

Modification

12.0(7)XK

This command was introduced.

12.1(2)T

This command was integrated into Release 12.1(2)T and Release 12.1(2)T.

Usage Guidelines

Caution Use this command with caution, because it displays every packet that the D channel transmits to the packet network and to the PBX. This command is CPU-intensive and should be used only as a last resort.

Use this command to debug a transparent CCS connection in the following cases:

•Observe the results of the ccs connect command results when you configure the setup.

•Observe CCS traffic at run time; the output shows the actual CCS packets received at run time and the number of packets received and sent.

Examples

The following example shows output from the command on both the originating and terminating sides:

debug tdm

To display time-division multiplexing (TDM) bus connection information each time a connection is made on Cisco AS5300 access servers, use the debug tdm command in privileged EXEC mode. To disable debugging output, use the no form of this command.

debug tdm [api | detail | dynamic | pri | test | tsi | vdev]
no debug tdm [api | detail | dynamic | pri | test | tsi | vdev]
Syntax Description

api

(Optional) Displays a debugging message whenever the TDM subsystem application programming interface (API) is invoked from another subsystem.

detail

(Optional) Displays detailed messages (i.e., trace messages) whenever the TDM software executes.

dynamic

(Optional) Displays TDM debugging information whenever a backplane timeslot is allocated or deallocated.

pri

(Optional) Routes modem back-to-back connections from the modem-to-PRI board to modem board. By default, the modem back-to-back connections route from modem board to motherboard to modem board.

test

(Optional) Simulates the failure of allocating a TDM timeslot. Verifies that the software and TDM hardware recover from the failure.

tsi

(Optional) Displays debugging information about the TSI Chip MT8980/MT90820 driver.

vdev

(Optional) TDM per voice device debug <0-2> slot and port number (that is, 0/1). Displays debugging information whenever a modem board TDM connection is made.

Command Modes

Privileged EXEC

Usage Guidelines

The debug tdm command output is to be used primarily by a Cisco technical support representative. The debug tdm command enables display of debugging messages for specific areas of code that execute.

Examples

The following examples show the turning on of the debug option, performing a modem call, and turning off the debug option:

Usage Guidelines

There is always a performance penalty when using debug commands.

The "We already have connection with such itad/tripid combo in progress" message appears when an error occurs where two location servers with the same Internet Telephony Administrative Domain (ITAD), and TripID initiate a Telephony Routing over IP (TRIP) connection to the gateway. When the second OPEN message arrives at the gateway, the debug trip error command displays the message.

Examples

The following example shows output from the debug tgrep error command:
Errors : Process socket event has an invalid fd to work on
Errors : Process socket event has an invalid fd to work on

Command Modes

Privileged EXEC

Command History

Release

Modification

12.3(1)

This command was introduced.

Usage Guidelines

There is always a performance penalty when using debug commands.

A watched queue is used to inform the TRIPR process about changes in any of the interesting attributes of dial peer that potentially could trigger TRIP update. A dial peer attribute change manifests into a prefix attribute change and is deposited into the watched queue of TRIPR by the Event Dispatcher. The trunk group system also does the same.

Examples

The following example shows output from the debug tgrep tripr command:

Usage Guidelines

V.120 is an ITU specification that allows for reliable transport of synchronous, asynchronous, or bit transparent data over ISDN bearer channels.

For complete information on the V.120 process, use the debug v120 packet command along with the debug v120 event command. V.120 events are activity events rather than error conditions.

Examples

The following is sample output from the debug v120 event command of V.120 starting up and stopping. Also included is the interface that V.120 is running on (BR 0) and where the V.120 configuration parameters are obtained from (default).

%HP100VG-5-LOSTCARR: HP100VG(2/0), lost carrier

Lost carrier debug message. The VG controller detects that the link to the hub is down due to cable, hub, or VG controller problem.

Check, repair, or replace the cable or hub. If you determine that the cable and hub are functioning normally, repair or replace the 100VG-AnyLAN port adapter.

%HP100VG-5-CABLEERR: HP100VG(2/0), cable error, training failed

Bad cable error messages. Cable did not pass training.¹

Check, repair, or replace the cable or hub. If you determine that the cable and hub are functioning normally, repair or replace the 100VG-AnyLAN port adapter.

%HP100VG-5-NOCABLE: HP100VG(2/0), no tone detected, check cable, hub

No cable attached error message. The VG MAC cannot hear tones from the hub.1

Check, repair, or replace the cable or hub. If you determine that the cable and hub are functioning normally, repair or replace the 100VG-AnyLAN port adapter.

HP100VG-1-FAIL: HP100VG(2/0), Training Fail - unable to login to the hub

Training to the VG network failed. Login to the hub rejected by the hub.1

Take action based on the following error messages:

•%HP100VG-1-DUPMAC: HP100VG(2/0), A duplicate MAC address has been detected

•HP100VG-1-LANCNF: HP100VG(2/0), Configuration is not compatible with the network

•%HP100VG-1-ACCESS: HP100VG(2/0), Access to network is not allowed

%HP100VG-1-DUPMAC: HP100VG(2/0), A duplicate MAC address has been detected

Duplicate MAC address on the same VG network. Two VG devices on the same LAN segment have the same MAC address.

Check the router configuration to make sure that no duplicate MAC address is configured.

%HP100VG-1-LANCNF: HP100VG(2/0), Configuration is not compatible with the network

Configuration of the router is not compatible to the network.

Check that the configuration of the hub for Frame Format, Promiscuous, and Repeater bit indicates the proper configuration.

%HP100VG-1-ACCESS: HP100VG(2/0), Access to network is not allowed

Access to the VG network is denied by the hub.

Check the configuration of the hub.

%HP100VG-3-NOTHP100VG: Device reported 0x5101A

Could not find the 100VG PCI device on a 100VG-AnyLAN port adapter.

Make sure the 100VG-AnyLAN port adapter is properly seated in the slot. Otherwise repair or replace the 100VG-AnyLAN port adapter.

%HP100VG-1-DISCOVER: Only found 0 interfaces on bay 2, shutting down bay

No 100VG interface detected on a 100VG-AnyLAN port adapter in a slot.

Make sure the 100VG-AnyLAN port adapter is properly seated in the slot. Otherwise repair or replace the 100VG-AnyLAN port adapter.

¹This message might be display when the total load on the cascaded hub is high. Wait at least 20 seconds before checking to determine if the training really failed. Check if the protocol is up after 20 seconds before starting troubleshooting.
