Alternate Stacking for X450-G2 Switches
Alternate stacking (SummitStack-V) is supported for the X450-G2 10GE4 switch models, as
summarized in Table 124. Use the front-panel 10G ports for alternate stacking.

Additional Stacking Considerations for X450-G2 switches
Before deploying a new stack with X450-G2 switches, consider the following guidelines:
• Only the SummitStack-V and SummitStack-V84 stacking protocols are supported for the X450-G2
switch. SummitStack-V80 is not supported.
• In a stack that contains X450-G2 switches and other switch models, the X450-G2 switch might
provide more memory and more features than the other switch models. Take this into account when
you decide which switches will serve as the master and backup nodes, and when you
configure
failover operation.
• To use the failover feature in the stack, a second X450-G2 switch is recommended. It must be the
backup node.
• If any supported feature pack is installed on the master-capable X450-G2 nodes, the following
guidelines apply:
◦ Every switch in the stack must meet the software and hardware requirements listed in the
Feature License Requirements document.
◦ Only the enhanced stacking protocol is supported for the X450-G2 switch. Every node that
shares a stack with an X450-G2 switch must have enhanced stacking configured.
◦ We recommend against mixing X450-G2, X460-G2, X770, and X670-G2 switches in a stack.
◦ X450-G2 switches support multiple types of QSFP+ stacking cables for connection between rear
stacking ports (21 Gb ports) and QSFP+ ports on other Extreme Networks switches. For
