| Nov 10, 2017 at 15:02 | comment | added | Hung Tran | @JFL Agreed that we should not have a dedicated L2 segment just for a few management connections. Then my answer addressed first two of your quesntions :) And the last one, puting mgmt0 into a vrf instance, I will think about that either. | |
| Nov 10, 2017 at 14:37 | comment | added | JFL | I got your point, but this is not what I wan to achieve. Requiring a pure layer 2 management network for an enterprise class switch is nonsense. And the fact I can actually reach the mgtm interface through routing when there's a route for it in the main routing table prove that is it not isolated from the main forwarding plane. That's NOT OOB. | |

| Nov 10, 2017 at 13:51 | comment | added | JFL | The mgmt interface was reachable from a remote network when there was no other route installed. As soon as I added a route for normal switch operation the interface was no more reachable.This cleary show that it is in no way isolated. I perfectly know what is written in the documentation, but it is not how the switch behave in practice. | |
| Nov 10, 2017 at 11:32 | comment | added | Hung Tran | @JFL some cases I know, you have a Terminal host/server resides in OOB Management network (probably L2 only segment). If you want to access devices in your network through OOB, you have to jump into this host/server first then access those devices. | |

@JFL This is written in their document Mellanox switches support out-of-band (OOB) dedicated interfaces (e.g. mgmt0, mgmt1) and in-band dedicated interfaces and In-band management is a management path passing through the data ports. In-band management can be created over one of the VLANs in the systems. In this case, if you access this box via Mgmt interfaces, it is OOB.

| Nov 10, 2017 at 10:44 | comment | added | JFL | yes it shoudl be, but the problem is that it's not OOB at all, but inband. It is in the same instance as the other switch configuration, since the switch act as layer 3 with an IP route for traffic routed for the switch, the management interface use this route and is not reachable | |
