Information Required by the Technical Assistance Center (TAC)
The following information is required to open a Support Case :
•Customer/Account Name
•Appliance Serial Number
•Appliance Software version
•Problem/Issue Description in detail with any error messages or screenshots.
•Is this issue impacting your production network? - Yes/No
•Timezone of Fabric
•Time of Incident
•Underlay / Overlay Topology overview
•Appliance Logs
oSystem, Event & Audit log files - /nvOS/log directory
onvOSd.log* - /var/nvOS/log/ directory
oCore files (If any) - /var/nvOS/log/cores directory
ovport tables - /var/nvOS/etc/vport/ directory
Procedure to Collect the Appliance Logs
|
CLI (network-admin@plu005swl08) > save-diags export-sftp This will save information about the running system. Please enter your username and password to confirm. Username (network-admin): Password: Diagnostics exported to /sftp/export. Use sftp to retrieve files for uploading to Pluribus customer support. |
To connect the appliance using SCP, enable SFTP via the CLI using the command: admin-sftp-modify enable
TAC Support Preferences
1.The use of the save-diags command is the preferred method to capture troubleshooting data with the following assumptions and conditions:
•The fabric/network is stable.
•Switch CPU/Memory/Disk utilization is stable.
•Capture data from all switches using a serial process and not in parallel. Do not run the save-diags command at the same time on all switches.
Caution: If the fabric is unstable and a switch has high CPU/Memory usage, avoid using the save-diags command.
2.The tech-support command (auto captured as part of the save-diags command) is less resource intensive than the save-diags command. Note that several commands are captured in local scope instead of fabric scope only, will add details in supplement attachments.
3.In an unstable situation, running single individual commands is the preferred method for troubleshooting.
Note: Steps 1-3 are useful only if a switch is online. If a switch is offline (unable to log in as network-admin but can log in as admin), then live debugging is required.
Tech Support Command
This document contains references to and examples and excerpts from the tech-support command.
Output content from the tech-support command may be very lengthy and generate a huge text file.
Note: The Tech-Support command captures in local scope only.
