Switch Management Commands 2289
Changing the stacking link speed requires a reboot of the affected switch.
21G stacking is not compatible with 40G stacking. All stacking links in a stack
must be configured to use the same speed.
Changing the speed of one stacking link changes the speed on the adjacent
stack port on the switch being configured as well. The connected switch stack
port(s) must be similarly configured. It is not possible to operate the stacking
links on a switch at different speeds. Clearing the configuration does not
affect the stack port speed settings.
Command History
