Summit X450G2 Stack Configuration Guidelines
Before deploying a new stack with Summit X450G2 switches, consider the
following guidelines:
- X450-G2 supports 84G native stack using rear panel 21Gb stacking ports and 10G SummitStack-V
using front panel 10G ports.
- Only X450-G2 supports V84G Stacking and existing summit platforms not supports V84 stacking.
- SummitStack-V80 is NOT supported on the X450-G2. Only SummitStack-V84 via the dedicated
rear-panel stack ports or SummitStack-V across the front-panel 10GbE ports are supported.
- In a stack that contains Summit X450G2 switches and other Summit switch
models, a Summit X450G2 switch might provide more memory and more features than other Summit
switch models, and this affects master node selection, backup node selection, and failover
operation. Before configuring a stack with Summit X450G2 switches and other Summit switch
models, review Configuring the Master, Backup, and Standby Roles.
- To use the failover feature in the stack, a second Summit X450G2 is
recommended, and it must be the backup node.
- If any supported feature pack is installed on the master-capable nodes,
the following guidelines apply:
- Each stack switch must meet the software and hardware requirements
listed in the Feature License Requirements document
- Only enhanced stacking protocol is supported on X450G2 and same
protocol should be configured on each Summit family switch in X450G2 stack.
- Although you can mix Summit X440, X450-G2, X460, X460G2, X480, X670,
X670G2 and X770 switches in a stack, we recommend that you do not mix these switch
types.
- Summit X450G2 switches support multiple types of QSFP+ stacking cables
for connection between VIM-2q ports and QSFP+ ports on other Summit switches. For information
on which cables to use with each type of Summit family switch, see the Summit Family Switches Hardware Installation Guide.
