ICX 7850 configuration notes

Keep the following points in mind when configuring ICX 7850 stack units.
• If an ICX 7850 unit has any port configured for breakout into sub-ports, attempts to enable the unit for stacking will fail.
Remove the breakout configuration before enabling stacking on the unit. Refer to the Ruckus FastIron Management
Configuration Guide for more information on breakout cable configuration.
• When using the manual construction method to add a new unit in a linear stack, make sure that the last unit of the
existing stack has both stack-ports or stack-trunks configured.
• Unused stacking ports can be used as data ports. For example, you can elect to use only one valid-stack-port as a
stacking port and the other valid-stack-port as a data port. Furthermore, when an ICX 7850 stacking module is not
configured for stacking, its stacking ports can be used as data ports.
• To configure a stacking trunk manually on a stack unit, use the stack-trunk command. However, in a live production
environment, use the multi-stack-trunk command as described in
environment on page 147.
• Only ports that are in sequential order can be configured as a stacking trunk.
• In a stacking system with two directions, ICX 7850 stacks support a maximum of four ports per trunk in one direction. As
an exception, a linear-topology trunk in a two-unit stack may contain up to eight ports.
• Stacking port speed is either 40-Gbps or 100-Gbps and is auto-detected based on the optics connected. Speed cannot
be manually configured.
• It is allowable (but not advised) to have a 100-Gbps trunk or port in one direction and a 40-Gbps trunk or port in another
direction.
• Ruckus recommends that you keep the same stacking link bandwidth across the stack.
• Ruckus recommends that all ports in the same stacking trunk be the same speed. When ports with different speeds are
in the same trunk, a warning message is displayed in the output of the show stack command as shown in the following
example.
