show as detached in the show interfaces status command output. When
downgrading switch firmware, Ethernet ports configured as stacking revert to
Ethernet ports. It is necessary to configure the Ethernet ports as stacking on
each unit in the stack individually after a firmware downgrade.
Use the show switch command to display information regarding the switches
in a stack. Fortygigabitethernet ports are only supported on the N4000 series
switches. Redundant stacking links between any two units must operate at
the same speed. A 40G port configured in 4x10G mode is considered to be
operating at 10G speed.
Up to eight stack ports can be configured per stacking unit (four in each
direction).
The N4000 series switches support up to twelve units configured in a stack
and can utilize 10GBaseT, SFP+ or QSFP (N4000 series only) connections
for stacking. The N3000 and N2000 series switches support up to twelve unit
configured in a stack and can utilize rear panel mini-SAS ports only for
stacking.
Example
console(config-stack)#stack-port tengigabitethernet 1/0/3 stack
console(config-stack)#
stack-port interface shutdown
Use this command to enable or disable the stack port administratively. This
command is usually used to diagnose the stack in case any one of the stack
ports is exhibiting errors.
