Introduction
This document defines trunk errors reported by the Cisco IGX 8400 Series Switch network trunk module (NTM). The trunk errors are similar to those reported by the IPX network trunk card (NTC) for Cisco WAN Switching System Software Release 9.1 and earlier. The IPX is not supported by switch software release 9.2 and later.
To use this document, select the link from the table below to go to the target trunk error pages, which provide the definitions and troubleshooting steps.

Statistical Alarms |
Integrated Alarms |
|---|---|
Use the following commands to troubleshoot trunk problems.
|
dsptrks |
A current view of all trunks and their status at the node. |
|
dsptrkerrs |
A current and historical view of status for all trunks at the node. To ensure a current view, use the clrtrkerrs command. |
|
dsptrkerrs <slot_number> |
A current and historical view of specified trunk status at the node. To ensure a current view, use the clrtrkerrs <slot_number> command. Before troubleshooting, use the clrtrkerrs <slot_number> command to ensure error counters are registering current events. |

NTM Trunk Alarm Types
Statistical Alarms are displayed in the left-hand column and Integrated Alarms are displayed in the right-hand column of a dsptrkerrs screen as follows:

If dsptrks shows the trunk as Clear-OK, no immediate action is required. Increasing error counts in the Statistical Alarm column typically cause minor alarms. Such alarms indicate that the trunk is experiencing errors but has not failed.
If error counts in the Statistical Alarm column exceed the threshold specified in the cnflnalm display, then a major alarm will be declared and the trunk will be removed from service. All connections are routed off the trunk or fail if no alternate trunk is available. Errors in the Integrated Alarm column typically cause major alarms.
If a new trunk experiences persistent Integrated Alarms, use the cnftrk <slot number> command to verify the trunk configuration.
Note: Virtual trunks are not supported by the NTM. Therefore, the VTRK Path Fails integrated alarm is not applicable and is not defined.
