Stacking

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

Dell 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 four platforms (S3124, S3124F,

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 four platforms. By default, stacking is enabled. The master unit can

configure all the options in the member units.

Important points to remember:

• All the four 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 configure 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 four switches in the S3100 series.
