I have 2 SN2010 switches in MLAG. Peerlink is up, MLaG status shows that everything is in great shape. No issues, no conflicts etc.
But when I do ip link show, the non-peerlink bond shows UP but instead of default it says DORMANT, and the swp interfaces in the bond are up and default mode.
This is on both switches in the pair. It’s passing traffic and working as it should, so I am confused how the bond can be DORMANT if it’s passing traffic?!?
The docs seem to indicate that this is expected behavior because the non-peerlink bonds are “downlink” bonds but doesn’t elaborate or explicitly just come out and say it.
Thanks!
What does your 'nv show interface" output look like in this case?
