Dell N3024, N2048 manual Mlag Peer B Mlag Peer C Description of commands

In a full mesh, all eight ports joined together in the MLAG (four blue cables) are in the same port channel to achieve maximum redundancy.

To configure the 2-tier in a full mesh configuration, follow the steps below:

1.Enter the commands below for each corresponding switch in the topology.

2.Cable the configuration as shown.

3.Enable MLAG (using the feature vpc command) on each switch.

Similar commands are performed on all four MLAG peer switches. MLAG peers B and C are required to be consistent in their configurations following the guidelines set in Consistency of MLAG peers. MLAG peers D and E also follow the same requirements for consistency. Though MLAG partner switches A and F may have similar configurations in this particular scenario, they have no such consistency requirements to each other or to the peer switches.

Each column below contains commands that can be cut and pasted into a CLI session if using the same topology as described in this example. Command sections are color-coded to allow easier comparisons between the BC MLAG peers and the DE MLAG peers.
