is not supported. Reboot the switch and examine the output of the show
switch stack-ports command to determine the active configuration. The clear
config command does not change the stacking port mode. Only the stack-
port command can change the operating mode of the stacking port and it
only takes effect after a reboot.
The stack-port configuration mode does not appear in the running config.
Use the show switch stack-port command to display configuration and status
of stacking ports. Ethernet ports that are configured to operate as stacking
ports will show as detached in the show interfaces status command output.
Use the show switch command to display information regarding the switches
in a stack. Redundant stacking links between any two units must operate at
the same speed. The available stacking speeds (and corresponding syntax)
varies depending on the switch model.
Up to eight stack ports can be configured per stacking unit (four in each
direction) on switches with more than two stacking ports.
The N3000-ON/N3100-ON/N3200-ON Series switches support up to twelve
units configured in a stack and can only utilize the rear panel mini-SAS ports
for stacking. The N2000/N2100-ON/N2200-ON Series switches support up to
eight units configured in a stack using the fixed stacking ports. The N1100-
ON and N1500 Series switches support stacking up to four units in a stack
and can utilize pairs of SFP+ ports for stacking.
On the N1100-ON/N1500 Series switch, configuring an SFP+ port as
stacking will always configure the adjacent port on the unit being configured
in stacking mode as well (i.e., configuring Te1/0/1 as stacking configures
Te1/0/2 as stacking and configuring Te1/0/3 as stacking configures Te1/0/4 as
stacking).
Changing the stacking link speed requires a reboot of the affected switch. 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 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.
