When using auto detection the SFP ports on LANCOM switches can only detect the SFP module. Die SFP-Ports auf LANCOM Switches können bei automatischer Aushandlung lediglich das SFP-Modul erkennen. Eine Geschwindigkeits-Aushandlung zwischen den beiden verbundenen Switches erfolgt nicht. Wird beispielsweise ein Switch mit einem 10 GBit SFP+ Modul mit einem Switch mit einem 1 GBit SFP-Modul verbunden, kommt der Link nicht zustande. Daher muss die Geschwindigkeit unbedingt fest eingestellt werden (auf beiden verbundenen Switches der gleiche WertNo negotiation is done between the two connected switches. If for example a switch with a 10 GBit SFP+ module is connected to a switch with a 1 GBit SFP module the link cannot be established. Therefore the link speed must be set to a fixed value (the same value on both switches).
This article describes how the speed for the SFP ports can be set on GSon GS-23xx, GS-3xxx or XS as well as GS-51xx 45xx series switches.

Make sure, that access to the management IP address of the device is possible via another or an additional port. If a connection via the SFP port cannot be established, access to the switch is still possible. The port configuration has to be made before plugging in the SFP module. |
Requirements:
- LANCOM Switch of the GS-23xx, GS-3xxx or XS as well as GS-51xx 45xx series
- Any web browser for accessing the webinterface
...
2) Set the speed for the used SFP port under Mode (ports 25 - 28).
XS and GS-51xx 45xx series:
1) Go to the menu System → Port → Summary → Port Summary and click the checkbox of a SFP port (ports 1 - 8) to edit its settings.
...
2) Check the checkbox Speed and select a port speed.

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). |
