Switch Management Commands 2346
stack-port
Use the stack-port command in Stack Configuration mode to configure ports
as either Stacking ports or as Ethernet ports.
NOTE: This command is only valid on the N1100-ON, N1500, N2100-ON, N2200-ON,
and N3100-ON switches. It issues an error response if used on the N2200-ON
switches.
Syntax
stack-port {twentygigabitethernet|tengigabitethernet} unit/slot/port
{ethernet|stack [speed {40g|21g}]}
• speed {40g|21g}—Set the stack port speed. The speed parameter is only
available on the Dell EMC Networking N2100/N3100 Series switches.
Default Configuration
By default, Ethernet ports are configured to operate in Ethernet mode. By
default, stacking ports are configured to operate in stacking mode. The
default port speed on the Dell EMC Networking N2100/N3000E/N3100
Series stacking ports is 21 Gigabit. The default speed on the Dell EMC
Networking N2200 stacking ports is 40 Gigabit.
Command Mode
Stack Configuration mode
User Guidelines
This command is used to configure Ethernet ports to operate as either
stacking or Ethernet ports, or to configure stacking ports to operate as
Ethernet ports or stacking ports.
Once this command has been issued, the switch must be rebooted in order for
the command to take effect. Issuing multiple stack-port commands for a
single interface without intervening reboots results in undefined behavior and
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.
