Overview of the Troubleshooting Process
To troubleshoot your network, follow these general steps:
Step 1 Gather information that defines the specific symptoms.
Step 2 Identify all potential problems that could be causing the symptoms.
Step 3 Systematically eliminate each potential problem (from most likely to least likely) until the symptoms disappear.
Overview of Best Practices
Best practices are the recommended steps you should take to ensure the proper operation of your network. We recommend the following general best practices for most networks:
•Maintain a consistent Cisco Nexus Virtual Services Appliance release across all network devices.
•Refer to the release notes for your Cisco Nexus Virtual Services Appliance release for the latest features, limitations, and caveats.
•Enable system message logging.
•Verify and troubleshoot any new configuration changes after implementing the change.
Troubleshooting with Logs
Cisco Nexus Virtual Services Appliance generates many types of system messages on the switch and sends them to a syslog server. These messages can be viewed to determine what events may have led up to the current problem condition you are facing.
Use the following commands to access and view logs in the Cisco Nexus Virtual Services Appliance:
•To view logs enter the following command:
show logging
•To view Cisco Nexus Virtual Services Appliance information enter the following command:
show tech-support nexus1010
•To access agent logs, enter the following command:
nexus-1010-system get agent logs
•To access agent logs, sos report, and other logs enter the following command:
vsa-system get agent logs
•To access redundancy logs, enter the following command:
show system internal redundancy trace
show system redundancy status
•To access default enabled logs, enter the following command:
show nexus1010-mgr internal event-history errors > bootflash:log
Note The output of nexus-1010-system get agent logs and vsa-system get agent logs command is the same. In the future, nexus-1010-system get agent logs command will be deprecated.
Accessing External USB/CD to View Troubleshooting Logs
In the event of any failure on the Cisco Nexus Virtual Services Appliance or loss in network connectivity, you can access an external USB or CD to copy the logs for troubleshooting.
You can use the following procedure to copy the logs
Step 1 Enable the auxillary feature using the following command:
switch# configure terminal
switch# [no] feature auxillary [cdrom|usb]
Step 2 Access an external USB or CD. The physical parameter represents a physical USB or CD drive. The virtual parameter represents a virtual drive that is mapped through the KVM console on the CIMC.
switch# [no] mount [physical |virtual]
Step 3 Copy the logs to the repository.
switch# copy bootflash:usb|v-usb|cdrom|v-cdrom| bootflash:repository
