show stacking {node-address node_address | slot slot_number} detail
• To unconfigure the stacking-support feature, use the following command:
unconfigure stacking-support
Note
Commands that contain the stacking-support keyword apply to the local switch only.
This means that each switch that will use alternate stacking ports must be configured
separately. When the stack is fully active, you can use the telnet slot slot-number
command to log in to another node over the stack to unconfigure SummitStack-V on that
node only. There is no way to intentionally or accidentally unconfigure the stacking-
support options on all nodes in a stack.
• When the stacking-support feature has been configured as required on all nodes in a stack, reboot
each node.
• Run the show stacking stack-ports command to verify that the stack has been properly
connected.
Combining Switches from Dierent Series
5520 Series switches can only stack with themselves using the SummitStack-V160.
Selecting Stacking Cables
Stacking connections using the native stacking ports require stacking cables that are
specific to the
type of stacking port. These cables are available from Extreme Networks in lengths from 0.5 meter to
100 meters.
Note
For the most recent information about available cables, contact your Extreme Networks sales
representative or refer to the Extreme Optics website.
Caution
Use of non-recommended cables or optics could cause stack instability.
Using the Extreme Stacking Tool
The Extreme Stacking Tool provides an easy way to plan your stack. As you select various switch
models and stacking methods, the tool shows you:
• What switch models can be stacked together and which cannot.
• Whether switching methods – for example, SummitStack-V and SummitStack-V80 (supported in
EXOS 30.1 and prior releases only) – are compatible with the selected switches.
• Statistics showing the routing options that are available with every stack combination.
• Recommendations about which switches should be the stack master and backup.
• Information about the supported versions of ExtremeXOS for every combination.
