LANCOM XS and GS-45xx series switches
Identical firmware version on all switches in the stack
LCOS SX as of version 5.00 (download)

The switches need to have an IP address (either assigned statically or obtained from a DHCP server).

Info
When connecting the switches, use only the DAC cables and SFP modules supported by LANCOM Systems.

Important information about stacking:

Info

Devices of the XS series only support stacking on certain ports. These are marked on the front panel accordingly (white circle with black number). Information is also available in the Quick Reference Guide enclosed with the switch.
When configuring Stacking on an XS-6128QF, please refer to the Knowledge Base article LANCOM Techpaper on configuration options for the aggregation switch LANCOM XS-6128QF regarding the different port configuration possibilities.
With stacking activated, it is not possible to use the LANCOM Management Cloud (LMC) to manage and monitor the switch.
Without stacking the switch can be managed and monitored via the LMC.
How to perform a firmware update for switches in a stack is described in this article.

Scenario:

This scenario collects two LANCOM aggregation switches (in this case LANCOM XS-5110F) into a stack.
Further IT infrastructure is then connected to the stack, e.g. a LANCOM fully managed access switch of the type LANCOM GS-3xxx and a network server

Procedure:

Hinweis
Explicit task steps for setting up a stacking scenario are specified in the following. We recommend that you follow this sequence.

Step 1: Configuring stacking on the switch ports

Info

Do not connect the switches with the stacking cables yet but configure stacking on the switches first !

When configuring stacking the stacking ports can be operated exclusively with the native port speed. Therefore with stacking it is not possible to use an SFP module with a lower speed than the native port speed on these ports (e.g. a 1 GBit SFP module on a 10 GBit port).

1.1 Open the configuration of the switches that are to operate in the stack and navigate to the menu Stacking → Base → Port Configuration.

1.2 Select the port to be used for stacking.

1.3 Activate the stacking feature by changing the interface mode from Ethernet to Stack.

1.4 Click the Save Configuration button (in the upper right corner of the configuration window). This saves the configuration to boot-persistent memory in the switch.
