Page 24: No More Stack Default-Ports Configuration
Changes to Stacking in FastIron Release 08.0.90 No more stack default-ports configuration stack-port 1/2/4 and keeps 1/2/1 because port 1/2/1 and port 1/3/1 satisfy the valid-stack-port set (1/2/1, 1/3/1, 6). If you configure stack-port 1/3/4, the system removes both old stack-ports because no valid-stack-port set contains both the ports in the new configuration, 1/2/x and 1/3/4.
Page 25: Changes To Stack-Port And Stack-Trunk Configuration
Changes to Stacking in FastIron Release 08.0.90 Changes to stack-port and stack-trunk configuration In all releases, when you enter the stack enable command, the system checks all stacking ports to make sure they contain no configuration. If any configuration is present, the stack enable command is denied.

Page 26: Comparison Of Configuration Changes That Use Non-Factory Valid-Stack-Port Sets
Changes to Stacking in FastIron Release 08.0.90 Changes to stack-port and stack-trunk configuration Comparison of configuration changes that use non-factory valid- stack-port sets The following table provides a side-by-side comparison of new and old configuration command behaviors for stack configurations that use stack-ports other than the factory-set default ports. In the table, an ICX 7750 stack serves as the example, and configuration changes use stack-ports other than the factory-set combination (ports 1/2/1 and 1/2/4).
Page 27 Changes to Stacking in FastIron Release 08.0.90 Changes to stack-port and stack-trunk configuration TABLE 6 Changing a stacking port to a stacking trunk New behavior Old behavior Initial configuration stack-port 1/2/1 stack-port 1/2/1 1/2/4 stack-port 1/2/4 Change stack-port 1/2/4 to stack-trunk 1/2/4 to 1/2/6 stack-trunk 1/2/4 to 1/2/6 stack-trunk 1/2/4 to 1/2/6...
Page 28 Changes to Stacking in FastIron Release 08.0.90 Changes to stack-port and stack-trunk configuration NOTE Completely removing a stacking trunk in the old behavior requires two steps. The first command, no stack-trunk, changes the trunk to a stacking port. The second command, no stack-port, is required to remove the trunk completely. Another option is to enter the command no stack-port 1/2/1, which removes both the stack-trunk and the stack-port configuration.

Page 32: Differences In Stack Unit Replacement
Changes to Stacking in FastIron Release 08.0.90 Stack interactive-setup NOTE If a discovered standalone unit is password protected, stack interactive-setup prompts you to enter the password. Stack interactive-setup checks for enable super-user password and ignores all other passwords. Ruckus recommends that you make all physical connections and run stack interactive-setup on the active controller of a stack or on a standalone unit that will become the active controller.
Page 33: Stack Zero-Touch Provisioning
Changes to Stacking in FastIron Release 08.0.90 Stack zero-touch provisioning NOTE Unit replacement cannot be performed when stack zero-touch provisioning is enabled. Stack zero-touch provisioning is a superset of unit replacement and can handle single or multiple unit replacements. NOTE If the unit replacement process cannot handle particular cases due to ambiguity, Ruckus recommends using stack interactive-setup.
Page 34: Stacking Deployment Guidelines
Changes to Stacking in FastIron Release 08.0.90 Stacking deployment guidelines Stacking deployment guidelines This section provides guidance for constructing a new stack, adding new members, replacing members, or adding new links within a stack. These tasks can be performed in several different ways. This section describes the most common methods. Other methods are discussed in more detail in later sections.
Page 35: Replacing Stack Units
Changes to Stacking in FastIron Release 08.0.90 Stacking deployment guidelines Replacing stack units Consider the following points when replacing stack members. • To replace a unit with a clean unit containing the same modules, simply disconnect the old unit and replace it with a clean unit using the same links.
Page 36: Support For Two-Unit Stack Linear-Topology Trunks
Changes to Stacking in FastIron Release 08.0.90 Support for two-unit stack linear-topology trunks To enlarge the connections between two units, configure the multi-stack-trunk command to change both ends of a live link at the same time. Then connect the new links. The links won't cause loops because they have proper stack- trunk configuration.
Page 37 Changes to Stacking in FastIron Release 08.0.90 Support for two-unit stack linear-topology trunks FIGURE 4 ICX 7250-24P two-unit stack with linear-topology trunk as configured in example NOTE If you configure an ICX 7750 two-unit stack, you would have the choice of two linear-topology trunks. You can configure stack-trunk 1/2/1 to 1/2/6 1/3/1 to 1/3/6 or stack-trunk 1/2/5 to 1/2/6 1/3/5 to 1/3/6.

Page 47 Changes to Stacking in FastIron Release 08.0.90 Support for two-unit stack linear-topology trunks Suppose the physical connections displayed only two-port trunk connections on each unit, for example, ports 1/2/3 to 1/2/4 and 2/2/3 to 2/2/4. To change the existing live configuration to a stacking ring, the multi-stack-trunk 1/2/3 to 1/2/4 and 2/2/3 to 2/2/4 command is required.
Page 48 Changes to Stacking in FastIron Release 08.0.90 Support for two-unit stack linear-topology trunks NOTE The preceding steps require the operator to enter commands to form trunks from data ports in steps 6 and 7. The following example summarizes the conversion of a two-unit stack linear-topology ring to a stacking ring topology and includes system output.

Page 50: Fastiron Stacking Distances And Optics By Device
Building a Stack Planning to build a stack FastIron stacking distances and optics by device Because Ruckus devices use Ethernet for the inter-switch stack connections, the deployment options are greatly increased. If standard copper stacking cables are used, the inter-switch connections can be up to 5 meters, which is usually sufficient for locally distributed stacks, such as in Top-of-Rack (ToR) applications.

Building a Stack Planning to build a stack with 802.1br switch port extender capability NOTE If STP is not enabled, there may be a loop issue when multiple cables are used to connect a standalone unit to a stack. The loop does not affect stack formation. The loop issue disappears after the multiple links are converted to stacking trunks when the standalone unit is integrated to the stack.
Page 56: Stack Construction Methods
Building a Stack Stack construction methods Stack construction methods NOTE The principles outlined in stack construction scenarios apply to all ICX devices. Figures used to illustrate a certain stack topology are not necessarily representative of other devices. For illustrations specific to a particular device, refer to the stack configuration section for that device, which also contains device-specific stacking considerations.
Page 57: Scenario 1 - Using Stack Interactive-Setup To Create A Stack
Building a Stack Stack construction methods Stack interactive-setup and the active controller When the stack interactive-setup command is issued on a unit that is not already the active controller, the unit becomes the active controller. If this unit does not already have an assigned priority and if no other unit in the stack has a priority higher than 128, stack interactive-setup assigns the unit a priority of 128 by default.

Page 200: Standby Controller Selection Based On Priority Configuration
Stack Management Stack unit priority Standby controller selection based on priority configuration You can choose a standby controller by configuring a stack unit with the second highest priority or with the same priority as the active controller. The standby controller takes over when the active controller fails. If the original active controller becomes active again, it does not win back its active role, which helps to minimize traffic interruption on the stack.
Page 201 Stack Management Stack unit priority You can assign the highest priority value to the stack unit you want to function as the active controller. When you enter a new priority value for a stack unit, that value takes effect immediately but does not affect the current active controller until the next reset.

Stack Management Configuring stacking trunks in a live environment Copying the flash image to a stack unit from the active controller You can replace a bad image on a stack unit or an image that does not match the active controller's image by copying the correct flash image from the active controller.
Page 208: Displaying Multi-Trunk Stacking Configuration
Stack Management Configuring stacking trunks in a live environment Displaying multi-trunk stacking configuration The multi-stack-trunk command is used on live stacks and is effectively a combination of two stack-trunk commands to ensure that a trunk-to-trunk connection is created on both ends of a stack link simultaneously. When the multi-stack trunk command is used to create a trunk, the configuration is saved as stack trunk ports, and the running configuration displays the stack trunk details on both ends under the heading stack unit <unit>...

Stack Management Configuring stacking ports in a live environment • You cannot enter the stack switch-over command until the stack election is completed or until the multi-stack-trunk command configuration is complete. If you enter the stack switch-over command too early, the following warning message is displayed.
Page 210: Adding, Removing, Or Replacing Units In A Stack
Stack Management Adding, removing, or replacing units in a stack NOTE Both the multi-stack-trunk and the multi-stack-port commands perform numerous checks to make sure no unit would become unreachable. However, the checks have limitations. Verify the physical connections with the show stack connection command, and make sure that reducing or removing stack-ports or stack-trunks will not break the stack.
Page 211 Stack Management Adding, removing, or replacing units in a stack • The physical modules of the replacement unit must match one and only one provisional configuration, that is, a stored configuration without a physical unit present. • The replacement unit must be a clean unit. You can convert a unit to a clean unit using the erase startup-config command followed by the reload command without saving any configuration.
Page 212 Stack Management Adding, removing, or replacing units in a stack If the configuration is not static, enter the write memory command to change all dynamic configurations to static. A static configuration remains after the unit is removed. After the configuration is saved with the write memory command, all unit IDs are followed by an "S" as shown in the following example.
Page 213 Stack Management Adding, removing, or replacing units in a stack NOTE You can return a configuration-mismatched unit to operation by configuring the no stack unit command for the nonoperational unit from the active controller. This removes the entire stack configuration so the active controller can learn the configuration-mismatched unit as a new unit.
Page 214 Stack Management Adding, removing, or replacing units in a stack If you connect two clean units matching the physical modules of the units you removed, you can use the stack interactive- setup command.

Stack Management Managing stack partitioning When the reload command is entered on the active controller without the unit-id parameter as shown in the following example, the entire stack reloads. device# reload NOTE If you need to reload the active controller, use the stack switch-over command. When switchover occurs, the original active controller can be reloaded using the reload unit-id command.

Page 240: Troubleshooting Stack Interactive-Setup
ICX Stack Troubleshooting Troubleshooting stack interactive-setup Check to be sure you do not have any stacking to non-stacking connections. All platforms use proprietary link negotiation to detect whether a stacking port's neighbors are also stacking ports. The platforms then convert both sides from IEEE mode (used in data ports) to HiGig mode (used in internal ports).
