UDLD-Port has UniDirectional Link Detection (UDLD) disabled, shutdown, or in undetermined state.įlow control and PortFast-Port has received flow control disabled or if it has PortFast enabled. Or, if the spanning tree root is not set for a VLAN. Spanning Tree-One of these is set to default: A trunk port has a mode that is set to desirable and is not trunking or if the trunk port negotiates to half duplex.Ĭhanneling-Channeling mode is "on" or if a port is not channeling and the mode is set to desirable. Trunking-Trunk mode is "on" or if the port is trunking in "auto". This command helps to check the configuration for a parameter that appears valid but that can have a negative implication.

The command is supported in Cisco IOS Software Release 12.2(18)SXE1 or later. The only limitation during the run process is that the command reserves the file system for a finite time while the command accesses the boot images and tests their validity. The command does not impact switch functionality, and you can use it on a production network environment. It reads the system variables that correspond to the configuration and the states in order to raise warnings if there is a match to a set of predetermined combinations. The command does not modify any current variables or system states. The checks are intended to serve as an aid troubleshoots and maintenance of the system sanity. The checks are designed to look for anything that seems out of place. The command then compiles a list of warning conditions. The show diagnostic sanity command runs a set of predetermined checks on the configuration, along with a combination of certain system states. This catches any latent hardware failure and also resolves any backplane connection issues. In order to resolve this, set the diagnostic boot up level to "complete", and then firmly reseat module 4 in the chassis. This can be related to the first indication of a failing module. This issue can have two causes:Ī poor connection to the backplane (bent connector pin or poor electrical connection), or The error message %CONST_DIAG-SP-4-ERROR_COUNTER_WARNING: Module 4 Error counter exceeds threshold appears on the console of the Catalyst 6500. In order to monitor the logged messages, issue the show logging command or use a tool to monitor stations periodically. If you are still unable to determine the problem, or if the error message is not present in the documentation, contact the Cisco Technical Support escalation center. For further configuration information, refer to the Configure Router and Switch Devices document. For an overview of the system error messages, refer to System Messages Overview. Enable the appropriate level of logging and configure the switch to log the messages to a syslog server. Some of the messages are for informational purposes only and do not indicate an error condition. The system messages are printed on the console if console logging is enabled, or in the syslog if syslog is enabled. Troubleshoot Error Messages in the Syslog or Console This document is applicable to Supervisor Engine 1-, 2-, or 720-based Catalyst 6500/6000 switches. This document assumes that you have a problem symptom and that you want to get additional information about it or want to resolve it. Background InformationĬisco IOS Software refers to the single bundled Cisco IOS image for both the Supervisor Engine and Multilayer Switch Feature Card (MSFC) module. Refer to Cisco Technical Tips Conventions for more information on document conventions. If your network is live, ensure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration.
