Displays real-time transmit error statistics. The switch automatically refreshes the output unless otherwise specified.
port_list | Specifies one or more ports or slots and ports. |
stacking-port-list | Specifies one or more stacking slot ports for display. Applies to SummitStack and ExtremeSwitching series switches only. |
no-refresh | Specifies that auto-refresh is disabled. The output provides a real-time snapshot of the transmit errors at the time the command is issued. This setting is not saved. |
refresh | Specifies a continuous refresh of output. |
The switch automatically refreshes the output.
If you do not specify a port number or range of ports, error statistics are displayed for all ports.
If you do not specify the no-refresh parameter, the switch automatically refreshes the output (this is the default behavior).
If you specify the no-refresh parameter, the output provides a snapshot of the real-time transmit error statistics at the time you issue the command and displays the output in page-by-page mode (this was the default behavior in ExtremeXOS 11.2 and earlier). This setting is not saved; therefore, you must specify the no-refresh parameter each time you want a snapshot of the port transmit errors.
This status information may be useful for your technical support representative if you have a network problem.
Port Number.
For information about the available port monitoring display keys, see the show ports statistics command.
The following command displays transmit error statistics for all ports on an ExtremeSwitching switch:
# show ports txerrors
The following is a truncated sample output from this command:

This command was first available in ExtremeXOS 10.1.
The link state information was updated to include NP-Port not present in ExtremeXOS 11.2.
Support for the auto-refresh functionality and the no-refresh parameter were added in ExtremeXOS 11.3. Auto-refresh continually updates the display. The no-refresh parameter takes a real-time snapshot of the display at the time you issue the command.
The refresh keyword was added in ExtremeXOS 16.1.
This command is available on ExtremeSwitching X435, X440-G2, X450-G2, X460-G2, X465, X590, X620, and X695 series switches.
