Figure 28-10. MLAG Components

MLAG switches: MLAG aware switches running Dell Networking Series

switch firmware. No more than two MLAG aware switches can pair to form

one end of the LAG. 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 MLAG

switches. Port-channel limitations and capabilities like min-links and

maximum number of ports supported per LAG also apply to MLAG

interfaces.
