Figure 3-7: MLAG Components
MLAG switches: MLAG-aware switches running QNOS switch firmware. No more than two MLAG aware
switches can pair to form one end of the Port-channel. Stacked switches do not support MLAGs. In the above
figure, SW1 and SW2 are MLAG peer switches. These two switches form a single logical end point for the
MLAG from the perspective of switch A.
MLAG interfaces: MLAG functionality is a property of Port-channels. Port-channels configured as MLAGs are
called MLAG interfaces. Administrators can configure multiple instances of MLAG interfaces on the peer
