Stacking port: A physical interface on a stack unit that connects a stacking link. Stacking ports are point-to-point links
that exchange proprietary packets. Stacking ports cannot be configured for any other purpose while operating as
stacking ports. The number of available stacking ports depends on the platform. Some ports can be configured as either
stacking ports or regular data ports. Refer to the hardware installation guide for the specific device for more
information.
–
Stack-port: A configuration command used to define a single stacking port in one direction.
–
Stack-trunk: A configuration command used to define multiple stacking ports in one direction. A trunk is also
referred to as a link aggregation group (LAG).
•
Stack zero-touch provisioning (ZTP): Automatic discovery of stack members when stack zero-touch-enable is
configured. When stack zero-touch provisioning is enabled, the system performs stack interactive-setup every three
minutes in background, without any prompts to the user or opportunities for user input. The resulting configuration is
similar to running stack interactive-setup and accepting all suggested values.
•
Standalone unit: A unit that is not enabled for stacking, or an active controller without any standby controller or stack
members.
•
Static configuration: A configuration that remains in the database of the active controller even if the unit it refers to is
removed from the stack. Static configurations are derived from the startup configuration file during the boot sequence,
are manually entered, or are converted from dynamic configurations after a write memory command is issued.
•
Trunked stacking port (trunk): A trunk consists of multiple stacking ports and is treated as one logical link. It provides
more bandwidth and better resilience than individually connected ports. A trunk is often referred to as a link
aggregation group (LAG).
•
Unit replacement: The process of swapping out a unit with a clean unit that contains the same modules. Unit
replacement is periodically triggered in background and does not require any command entry.
•
Valid-stack-port set: A set of stacking ports that must be used to configure stacking. There are two stacking directions, so
each valid-stack-port set contains two ports. Each stack direction must start with a specific port in the valid-stack-port
set. For example, an ICX 7150-24P device has the valid-stack-port set (x/3/1, x/3/3, 2). In this notation, the "2" indicates
that a stack-trunk can have up to two ports. The stack-port configuration must be a valid-stack-port (for an ICX 7150-24P,
x/3/1 or x/3/3). A stack-trunk configuration contains contiguous ports starting from a valid-stack-port, for example, for
an ICX 7150-28P device, stack-trunk 1/3/3 to 1/3/4. A platform may support multiple valid-stack-port sets. Both
stacking directions must originate from the same set. For example, an ICX 7250 device has two valid-stack-port sets, (x/
2/1, x/2/3, 2) and (x/2/5, x/2/7, 2). When you configure an ICX 7250 for stacking, you cannot configure stack-port 1/2/1
and stack-port 1/2/5 in the same unit. For more information, refer to
on page 23 and to the
stacking overview section for a particular ICX device.
