Data Collection

These sections discuss various ways that data is collected and presented.

Encrypted or Open Text

Status reports are sent either in encrypted or clear text. By default, this is determined by the installation of the SSL module. If the SSL module is installed, the status report is sent using an SSL over TCP session in encrypted text. Otherwise, the status report is sent over a regular TCP session in clear text. You can disable the SSL transport even if the SSL module is installed by using the configure tech-support collector [hostname | ip_address] tcp-port port {vr vr_name} {from source_ip_address} {ssl [on | off]} command.

Push vs. Pull

For security reasons, status reports are never pushed from a collector out to a switch. The switch always pushes status reports to a collector. The first release of the tech-support application supports local configuration only. The switch pushes status reports to a collector based solely on the local configuration.

Report Format

The status report format is the output of the show tech-support command. You can limit the amount of information in the report using the data-set configuration parameter. Two data-sets are available in the first release. With SSH, we recommend that you configure the data-set as detail to include all output of the show tech-support command in the switch status report. Without SSH, we recommend that you configure the data-set as summary to include certain output of the show tech area command in the switch status report for just a few critical areas, such as general, config, log, VLAN, and EPM.


You can also configure when the switch sends a status report. The switch can send a report based on a critical severity event occurrence, daily, at boot-up, or manually when directed by the network administrator. Because of the amount of information that can be transmitted, automatic status reports are sent no more frequently than one report per hour. When a series of critical severity events occurs, only the first one triggers the switch to send status reports. All other critical severity events that occur within one hour after the first critical severity event are ignored.

Authentication and Verification

To keep the required configuration minimal, the ExtremeXOS tech-support application does not perform authentications. The switch does not verify that the collector is a valid, authorized server before starting the transmission, but the data that has to transmitted is encrypted.

You can discard or purge the status report from the database for the following reasons:
  • The status report is not in a valid format.
  • The status report does not contain the minimum required information.
  • The serial number of the hardware in the status report is invalid or does not match any serial number in Extreme Network‘s manufacturing database.
  • The status report is received from the same device more than once per hour.
