- Link Aggregation is activated on ports, where high amounts of data have to be transmitted (e.g. an uplink to another switch or to a server).
- In contrast to a Static Trunk the feature LACP supports a dynamic negotiation, thus enabling the Trunk to remain active when a line fails. LANCOM Systems therefore recommends to always use LACP when combining switch ports to a trunk.
- The ports used for Link Aggregation must have the same speed (e.g. two ports with 10 GBit/SekSec.).
- VLAN settings must be the same on all aggregation ports so data can be transmitted.
...
- NIC teaming / Link Aggregation is activated on ports, where high amounts of data have to be transmitted (to a Windows Server).
- When a managed switch is used, LANCOM Systems recommends to always use the mode LACP.
- The mode Switch Independent on the Windows servershould only be used with an unmanaged Switch.

- Spanning Tree wird immer auf Ports zu einer weiteren Netzwerk-Komponente konfiguriert (z.B. ein Router oder ein Switch).
- STP is deprecated and should not be used anymore.
- In most scenarios it makes sense to use RSTP. There is one instance for the whole network. In contrast to STP topology changes happen much faster with RSTP, thus minimizing downtimes.
- In some scenarios it can be useful to use MSTP. It is used for a VLAN group (a group with only one VLAN is also possible) and forms an instance for each group.
- On GS-23xx and GS-3xxx switches Spanning Tree has to be activated separately for Link Aggregation:
- GS-23xx: In the menu Configuration → Spanning Tree → CIST Ports the option STP Enabled has to be activated under CIST Aggregated Port Configuration.
