Summit X670 Stack Configuration Guidelines
Before deploying a new stack with Summit X670 switches (except X670-48x),
consider the following guidelines:
- In a stack that contains Summit X670 switches and other Summit switch
models, a Summit X670 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 X670 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 X670 is
required, and it must be the backup node.
- Only the master and master-capable nodes require a license to support
special features such as MPLS.
- If the MPLS 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.
- You must configure the enhanced stacking protocol on each Summit
family switch.
- Although you can mix Summit X440, X450-G2, X460, X460-G2, X480,
X670, and X770 switches in a stack, we recommend that you do not mix these switch types
if the desired routing table exceeds the supported limit for the Summit X670 switch,
which is 12K IPv4 LPM routes.
- Summit X670V switches support multiple types of stacking cables for
connection between the VIM4-40G4X option card and 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.
- Non-stacking ports (45 and 46) are unavailable when alternate stack ports (47 and 48) are
used for stacking.
