This command has no arguments or variables.
|Stack Port column||Displays rows for Stack Port 1 and Stack Port 2.|
|Native column||Indicates whether the switch has native stack ports. A Yes entry indicates that
the switch has native stacking ports. A No entry indicates that
no native stacking ports are present.|
An asterisk indicates that the native stack port is selected.
|Alternate column||Displays the port numbers for data ports that can operate as alternate stack
ports. A No entry indicates that there are no data ports that
can operate as alternate stacking ports.|
An asterisk indicates that the data port number is selected as an alternate stack port.
|Configured column||Indicates the configured state for stack ports 1 and 2, which can be Native or
This column also indicates the configured state of stacking-support option. For platform configurations with dual-purpose hardware (that supports stack ports or data ports), this column displays either Enabled (stack ports enabled) or Disabled (stack ports disabled, data ports active). For platform configurations without dual-purpose hardware, this column displays N/A, which indicates that stacking-support option cannot be disabled on this switch.
This is the configuration that becomes active the next time the switch boots if the stacking-support option is enabled.
For more information, see the command descriptions for the enable stacking-support and disable stacking-support commands.
|Current column||Indicates the selection that is currently in effect for stack ports, which can be
Native, Alternate, or N/A. N/A indicates that the port selection
is not applicable to this switch hardware configuration.|
The column also indicates the current operating state of the stacking-support option, which can be Enabled, Disabled, or N/A. An N/A entry indicates that no option card is present.
This is the configuration that is active now.
The following example shows the stack port selection and stacking-support option configuration after the unconfigure stacking-support command has been executed and before a subsequent reboot has been initiated:
# show stacking-support Stacking Support Settings Stack Available Ports Port Native Alternate Configured Current ----- ----------------- ---------- ---------- 1 Yes * 23 Native Native 2 Yes 24 * Native Alternate stacking-support: Disabled Enabled auto-discovery: Enabled Disabled Flags: * - Current stack port selection NOTE: This node must be rebooted before the configured settings will take effect.
The following example shows that the stacking-support option is disabled and will remain disabled when the switch reboots:
# show stacking-support Stacking Support Settings Stack Available Ports Port Native Alternate Configured Current ----- ----------------- ---------- ---------- 1 No S3 Native N/A 2 No S4 Native N/A stacking-support: Disabled Disabled auto-discovery: Enabled Enabled Flags: * - Current stack port selection
# show stacking-support Stack Available Ports Port Native Alternate Configured Current ----- ----------------- ------------- ------------- 1 Yes * 47 Native (V160) Native (V80) 2 Yes * 48 Native Native (V320) stacking-support: Enabled Enabled auto-discovery: Enabled Enabled Flags: * - Current stack port selection
This command was first available in ExtremeXOS 12.5.
Ability to show configured and current pseudo native stack port type (V160, V320, V400) was added in ExtremeXOS 30.1.
Stacking auto-discovery information was added in ExtremeXOS 30.3.
This command is available on all platforms that support alternate stack port selection or permit disabling of the stacking-support option.
