This document describes how to configure stacking on the LANCOM switches of the XS and GS-45xx series.
When connecting the switches, use only the DAC cables and SFP modules supported by LANCOM Systems. |
|
Explicit task steps for setting up a stacking scenario are specified in the following. We recommend that you follow this sequence. |
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.
1.5 Repeat these configuration steps for each of the switches.
1.6 When all of the switches in the stack have been configured, they all have to be restarted (in the menu System → Utilities → System Reboot).
After restarting, the entire stack can only be reached via the IP address of the stack master. |
1.7 After successful configuration, the stacking status is displayed in the configuration.
1.8) Switch off all switches that have stacking configured on them and continue with the second step.
2.1) Connect all of the switches involved in the stack using the ports configured in step 1.
2.2) First power up the switch that is to operate as the stack master/manager and then all of the other switches in the stack.

You can decide which stack member is master by means of the “Admin Management Preference” in the menu Stacking → Base → Unit Configuration.
Unit preference for admin management:

The following events result in a change of the stack master/manager:
3.1 The stacking status can be viewed in the menu Stacking → Base → Summary:
3.2 The port status on the stack members can be checked using the drop-down menu next to the LANCOM logo.
