MAGNUM 6K SWITCHES, MNS-6K USER GUIDE
FIGURE 102 – Some valid LACP configurations.
Should trunks be created so as to span multiple ports, a “trunk mismatch” error message
is printed on the console. An example of an incorrect configuration is shown below.
Switch 1
Switch 2
F
IGURE 103 – an incorrect LACP connection scheme for Magnum 6K family of switches. All LACP
trunk 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 in
red) and other ports belong to VLAN 20 (shown in blue). If the port groups do not have a
common VLAN between them, LACP does not form a connection.

FIGURE 104 – 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.
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
