Summit X460 Stack Configuration Guidelines

Before deploying a new stack with Summit X460 switches, consider the following guidelines:

In a stack that contains Summit X460 switches and other Summit switch models, a Summit X460 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 X460 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 X460 is required, and it must be the backup node.
Beginning with ExtremeXOS Release 12.5.1, 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, X460, 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 X460 switch, which is 12,256 IPv4 LPM routes.
Summit X460 switches support multiple types of stacking cables for connection between Summit X460 compatible SummitStack option cards 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.
When a SummitStack option card is installed in a Summit X460 switch, the switch prompt remains unchanged.

Note

When MPLS is enabled on a stack, you can only add a MPLS-compatible Summit family switches to the stack.
