Note: Interfaces used to connect each peer to the partner switch LAG do not need to match on each peer. For instance, in the example above, one partner LAG interface connects to 1/0/47 on the primary peer while the other interface connects to 1/0/11 on the secondary peer.

2.Connect all cables as shown in Figure 4.

3.Run the show vpc brief command on either of the two MLAG peers to see which peer is the primary MLAG peer.

4.Run the show vpc brief command again from the primary switch to display all information for both peers.

Note: The partner switches must be configured with MLAGs and connected to the MLAG peers, or the “Number of VPCs operational” in the show vpc brief command shows 0.
