Depending on the switch model and the number and type of stacking ports, the bidirectional stacking link provides 40 Gbps, 80 Gbps, or 160 Gbps bandwidth.
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.
Available Stacking Cables for Summit Switches lists the cable types that have been verified by Extreme Networks for use as stack connection hardware, along with the Summit switches or modules with which each type is compatible.
Caution
Use of non-recommended cables or optics could cause stack instability.
