Uploads debug information files to a tftp server.

Syntax Description

ipaddress Specifies the IP address of the TFTP server to which the debug files will be uploaded to.
vr_name Specifies the name of the virtual router.
block_size Specifies the data block size, excluding TFTP header. Data block size ranges from 24-65000 bytes.

Usage Guidelines



Use this command only under the guidance of Extreme Networks Technical Support personnel to troubleshoot the switch.

Use this command to copy, upload debug information (for example, core, trace, show tech-support, configuration, and policy files) to the specified TFTP server.

Progress messages are displayed that indicate the file being copied and when the copying is finished. Depending on your platform, the switch displays a message similar to the following:

The following files on have been uploaded: Tarball Name: TechPubsLab_C_09271428.tgz ./primary.cfg 

You can also use this command in conjunction with the show tech-support command. Prior to uploading debug information files, the switch prompts you with the following message to run the show tech command with the logto file option:

Do you want to run show tech logto file first? (y/n) 

Enter y to run the show tech-support command before uploading debug information. If you enter y, the show_tech.log.tgz file is included during the upload. Enter n to upload debug information without running the show tech command.

After you upload the debug information, you should see a compressed TAR file, which contains the debug information.

The TAR file naming convention is:

<SysName>_<{<slot#>|A|B}I|C>_<Current Time>.tgz

where <Current Time> = mmddhhmm (month (01-12), day (01-31), hour (0-24), minute (00-59) ).


The following command uploads debug files to a network TFTP server:
