A stack consists of a group of up to eight switches that are connected to form a ring. The stack offers the combined port capacity of the individual switches. But it operates as if it were a single switch, making network administration easier.
Stacking is facilitated by the SummitStack feature – part of the ExtremeXOS Edge license.
This chapter contains information about configuring a stack, maintaining the stack configuration, and troubleshooting.
Refer to the Stacking chapter in the ExtremeSwitching and Summit Switches: Hardware Installation Guide for Switches Using ExtremeXOS 21.1 for descriptions of the supported configurations for stacking, the considerations for planning a stack, and the steps for setting up the hardware. We recommend that you read that chapter before installing the switches that will make up the stack.
