Using the SummitStack-V Feature
Summit Family Switches Hardware Installation Guide
201
If you configure an alternate stacking port on a switch that has native stacking ports, the native stacking
port becomes inactive and cannot be used. When a data port becomes an alternate stacking port, it can
no longer operate as a data port.
When you connect distant nodes using alternate stacking ports, be sure to run the cables over physically
different pathways to reduce the probability a cut occurring to both links.
See Table 64 for the ports that are available on each switch model that supports this feature. For each
switch model, the column labeled Alternate Stacking Port 1 shows the switch port that replaces native
stacking port 1, and Alternate Stacking Port 2 lists the switch port that replaces native stacking port 2.
Switch models that are not listed in the table do not support the SummitStack-V feature.
NOTE
The SummitStack-V feature is supported only on switches that are running ExtremeXOS 12.5.1 (or later).
