An example of an incorrect configuration is shown below.Switch 1Switch 2FIGURE 103 – an incorrect LACP connection scheme for Magnum 6K family of switches. All LACPtrunk ports must be on the same module and cannot span different modules.Another example is highlighted below where some ports belong to VLAN 10 (shown inred) and other ports belong to VLAN 20 (shown in blue). If the port groups do not have acommon VLAN between them, LACP does not form a connection.VLAN 20VLAN 10Switch 2Switch 1FIGURE 104 – In this figure, even though the connections are from one module to another, this is still not avalid configuration (for LACP using 4 ports) as the trunk group belongs to two different VLANs.However – on each switch, the set of ports can belong to same VLANs as shown in thefigure below. While the ports belong to the same VLANs, there is no common VLAN195
