F IGURE 99 – In this figure, even though the connections are from one module to another, this is still not a
valid configuration (for LACP using 4 ports) as the trunk group belongs to two different VLANs.
VLAN 20
VLAN 10
Switch 2
Switch 1
However – on each switch, the set of ports can belong to same VLANs as shown in the
figure below. While the ports belong to the same VLANs, there is no common VLAN
between the switches and hence the LACPDU cannot be transmitted. This configuration
will not work in the LACP mode.

IGURE 100 - In the figure above, there is no common VLAN between the two sets of ports, so packets
from one VLAN to another cannot be forwarded. There should be at least one VLAN common between
the two switches and the LACP port groups.
