How to Configure Stacking - DGS-3420-Series

This document is to achieve stacking of several units of switches. Please note that the maximum units that can be stacked are 12 switches from the same family including the master and backup master. The switch has two front ports for stacking which would allow it to use a ring topology stacking.


 
A chain stacking topology allows a maximum bandwidth of 20Gbps stacking up while closing the ring can reach up to maximum bandwidth of 40Gbps stacking.
Only the last two switch ports are intended to make the stacking, by default is automatically activated when you connect computers using ports destined for the stack. But if needed, activate the stacking by follow the steps in this document.

Stacking:

Step 1 - Enter the configuration of the Switch through your browser by entering the IP address of the switch, default IP address is 10.90.90.90 so you will need to enter http://10.90.90.90 



The default password is:

User: admin
Password: admin


Step 2 - Once inside the switch configuration go to:



System Configuration > Stacking > Stacking Mode Settings


Step 3 - Within the "Stacking Mode Settings" activate "Stacking Mode" setting the option to "Enabled" and click “Apply”.




• After applying the configuration click the "Save" option in the top menu



Save Configuration / Log

Type mark in the "ALL" option and click “Apply” to save the changes.



Step 4 - Turn on the Stacking in each of the switches, each are assigned automatically an ID and the role of "Master", if you want to force the state of "Master" to a particular switch, check only on that switch the option "Force master role" and if you also want to specify a different stack ID for each unit, the lower priority will not change the ID only indicate the order in which the role of master performed if the master is removed.



Remember once the settings are saved from the top menu as noted above.
