Stacking

Using the Dell EMC Networking OS stacking feature, you can interconnect multiple switch units with stacking ports . The stack becomes

manageable as a single switch through the stack management unit.

The system accepts Unit ID numbers from 1 to 12 and it supports stacking up to twelve units.

Stacking Overview

Dell EMC Networking OS elects a management (master) unit, a standby unit, and all other units are member units.

Dell EMC Networking OS presents all of the units. For example, to access GigabitEthernet Port 1 on Stack Unit 1, enter interface

tengigabitethernet 1/1 from CONFIGURATION mode.

Cross Platform Stacking

Starting from Dell Networking OS 9.10(0.0), stacking is supported on all the ve platforms (S3124, S3124F, S3148, S3124P, S3148P) in

S3100 series. You can stack up to 12 switches using the dedicated stacking ports.

You can stack the switches among all the ve platforms. By default, stacking is enabled. The master unit can congure all the options in the

member units.

Important points to remember:

• All the ve platforms can be stacked together.

• Only the switches that belong to S3100 series can be stacked. Other devices cannot be stacked with S3100 series switches.

• By default, the PoE commands are enabled. However, you cannot execute any PoE command in a non PoE device. If you try to execute

a PoE command in a non-PoE device, it throws an error.

• You can congure the PoE commands on a PoE supported device when it is connected to a non-PoE device.

• You can provision a slot with any of the ve switches in the S3100 series.

• When the slot contains the corresponding card type, all the congurations are synchronized to the slot.

• When there is a mismatch between the card type and the provisioned slot, the card does not come up online and remains in the type-

mismatch state. The congurations from the master are not synchronized.
