Configuring the cluster and switches with LACP
Configure the cluster in the same way it was defined in the previous use case. For more information, please refer to the section Configuring the cluster with LACP.
In the network diagram below (in which workstations are shown), the issue of network looping may arise.
Loops appear in a network when several different level 2 links (data link layer in the OSI model) exist between two active elements.
Stackable switches have to be equipped with a loop-free system in order to prevent stability issues in the MAC address table, or operate in active-passive mode.
However, no changes need to be made in the SNS cluster: whether an Ethernet frame containing the source MAC address of a workstation passes through switch 1 or switch 2, it will be presented to the cluster on the aggregated interface of the active node.
