show tech-support

Displays the output of several show commands at once. The output from this command varies depending on the router configuration.
Syntax
show tech-support [acl|cluster |cpu |license |l2 |l3| memory |multicast |packet-loss |stack]
no show tech-support [acl|cluster |cpu |license |l2 |l3| memory |multicast |packet-loss |stack]
Parameters
acl
Generates system and debugging information specific to ACL configurations and counters.
cluster

license
Generates license-related information.
l2
Generates system and debugging information specific to Layer 2 configurations.
l3
Generates system and debugging information specific to Layer 3 configurations.
memory
Generates memory-related information of the device.
multicast
Generates system and debugging information specific to Layer 2 and Layer 3 multicast configurations.
packet-loss
Generates packet statistics-related debugging information.
stack
Generates system and debugging information specific to stacking configurations.
Modes

Privileged EXEC mode

Usage Guidelines

The show tech-support command is useful when collecting a large amount of information about the RUCKUS FastIron devices for troubleshooting purposes. The output of this command can be used by technical support representatives when a problem is reported.

Note: Licensing and stacking is not supported on ICX 7150-ES and ICX 8100 devices.
Note: MCT is not supported on the ICX 7150 devices.

The default output of the show tech-support command includes the following information:

  • Header for all the show commands
  • Running configuration
  • Image version
  • Port status
  • Port counters
  • Static and dynamic log buffers
  • dm statistics
  • Boot, monitor, and system
  • Registers information
  • Possible stack trace
  • Active stack (if applicable)
  • Last packet (Application Data)
  • Possible data structure
  • MCT cluster details
  • License details
  • Stacking information
  • Dot1x
  • DHCP snooping
  • SSH
  • System Health

The format of the show tech-support command output is modified to include a header and a footer by default for each of the show tech-support commands which gets called from the CLI to automatically parse the output for easier lookup.

The header contains the following information:

  • BEGIN - Indicates a sub-command that will begin execution next.
  • CONTEXT - Indicates in which context and session the sub-commands are executed.

    If more than one telnet session and console session for a device is accessed, then show tech-support command displays CONTEXT as Console#0 for console session and telnet#1 and telnet#2 and so on for telnet sessions.

  • TIME STAMP - A time stamp, with millisecond granularity, helps to determine the time difference between separate runs of the same command.

    If NTP or local clock is not set in a device, then header displays Epoch time in the TIMESTAMP field. Epoch time is a universal time which starts from Jan 1, 1970. Therefore, for Linux platforms, the Epoch time format is 00:00:00.000 GMT+00 Thu Jan 01 1970. For non-Linux platforms, the Epoch time format is Jan 01 00:00:00.000.

  • HW/SW INFO - Indicates the hardware and software version information of the device.

The footer contains the following information:

  • TIME STAMP - A time stamp, with millisecond granularity, helps to determine the time difference between separate runs of the same command.

    If NTP or local clock is not set in a device, then header displays Epoch time in the TIMESTAMP field. Epoch time is a universal time which starts from Jan 1, 1970. Therefore, for Linux platforms, the Epoch time format is 00:00:00.000 GMT+00 Thu Jan 01 1970. For non-Linux platforms, the Epoch time format is Jan 01 00:00:00.000.

  • END - Indicates the sub-command which has completed execution.
  • TIME TAKEN - Indicates the total time taken in nanoseconds for the command execution.

You can disable the display of the header and footer for show tech-support commands by using the supportsave info disable command. If disabled, you can enable the display of the header and footer for show tech-support commands by using the supportsave info enable command.

The following sample output of the show tech-support license command shows the header and footer displayed.
