Page 48: Overview
Chapter 2: Virtual Chassis Stacking Overview The Virtual Chassis Stacking (VCStack) feature lets you build a virtual stack of two AT-x950-28XSQ switches. The feature allows the switches to function as a single networking unit, with the following benefits:  Simplifies management - You can manage the devices of the stack as a single unit, rather than individually.
Page 49: Stacking Guidelines
No additional software or license is required.  The default setting for the VCStack feature on the AT-x950-28XSQ Switch is disabled. Enabling it requires rebooting the switch. Instructions later in this guide explain how to enable the feature and reboot the unit.
Page 50: Stack Trunks

Figure 34. Invalid 100Gbps Stack Trunk of Base 100Gbps Slots and AT- XEM2-1CQ Line Cards  Allied Telesis does not recommend using the AT-XEM2-1CQ Line Card for a stack trunk because it has only one transceiver slot and the switch has only one expansion slot. Consequently, the trunk would have only one link.
Page 58: Additional Guidelines
Chapter 2: Virtual Chassis Stacking Additional Here are additional guidelines: Guidelines  The base 10Gbps transceiver slots and AT-XEM2-12XS Line Card support 1Gbps transceivers. However, stack trunks do not support 1Gbps transceivers.  Trunk links must be direct connections between ports on the switches, without any intervening network devices, such as media converters, routers, or other Ethernet switches.

AT-x950-28XSQ Switch and VCStack Installation Guide Master and Member Switches One switch of a stack functions as a master switch. Its main functions are listed here:  Coordinate and monitor stack operations.  Verify that the switches are using the same version of management software.
Page 60: Switch Id Numbers
Chapter 2: Virtual Chassis Stacking Switch ID Numbers Each switch must be assigned an ID number. The range is 1 to 4. The default is 1. The ID numbers are displayed on the ID LEDs on the front panels of the units. You can assign the numbers yourself or let the master switch assign the numbers automatically when you first power on the stack.
