Table 20: List of Stacking Terms (continued)
Term
Description
Operational node
A node that has achieved operational state as a card in a slot. The
operational state can be displayed using the
show slot {
slot
{
detail
} |
detail
}
command.
System uptime
The amount of time that has passed since the last node role election. You
can display the system uptime by entering the
show switch
{
detail
}
command on the master node.
Stack segment
A collection of nodes that form a stack topology. The term is useful when
a stack is severed. Each severed portion of the stack is referred to as a
stack segment.
Stack state
A state assigned by the stack to a node. You can display the stack state by
entering the
show stacking
command.
Easy Setup
A procedure that automatically configures the essential stacking
parameters on every node for initial stack deployment, and then
automatically reboots the stack to put the parameters into effect.
The choice to run Easy Setup is offered when you run the
enable
stacking {
node-address
node-address
}
command and the
essential stacking parameters are unconfigured or inconsistent. It can also
be invoked directly by running the
configure stacking easy-
setup
command.
Planning to Create Your Stack
Use the information in the following topics to plan the physical makeup of your stack – switches,
versatile interface modules (VIMs), and cables – and the stacking protocols you will use. Included are:
•
Guidelines and other information for each switch model in your stack
•
Considerations for combining different switch models in a stack
•
Information about stacking cables
Enabling and Disabling the Stacking-Support Option
The stacking-support option is enabled by default for many switch and option card configurations.
However, some configurations require you to enable the stacking-support option before a switch can
participate in a stack.
•
To enable stacking-support, issue the
enable stacking-support
command.
You must enable stacking-support individually for every switch in the stack that does not have
stacking support enabled by default.
•
To disable stacking support, configure the switch data ports to use the Ethernet protocol instead of
the stacking protocol.
Use the
disable stacking-support
command.
