Dear Sir,
My customer has two networks on different subnet  need to management with NetSight.
So I build two lan cards on ESXi Server and implement to NetSight.

But I can't find the second lan card on NetSight....
Even I edit the /etc/network/interfaces for the second lan card - eth1,
it can not work..

Could you kindly help me how to build 2 lan cards on NetSight?

Thanks for your help.

As far as I'm aware off you'd have only one IP address for Netsight.

But you'd have two NICs on the ESX connected to the same VM switch to have redundancy in case one NIC is down i.e. broken patch cable.

One NIC has default gateway, and another has not.
With the routing concept, the no default gateway NIC should can search it's own network,
and other network will search by the NIC with default gateway.

This can work on general network.
So I think it should be work with NetSight too.

And the problem is I don't know how to make the second NIC work on NetSight (VM).

Why aren't you routing between the networks? If you route you don't need two NICs. If you want isolation you can only route to Netsight from the network Netsight is not on. It weird and even if you pull it off you may run into support issues because it is a non standard install.

Thanks, I see.
I will change the routing between them.

This is possible-

I did this once for a customer that wanted separation of their switch management network from the production server network (that their PC's were on, and the Netsight server).

I hacked into Ubuntu, created an additional interface, gave it an IP and it was able to discover and communicate with the switches.

It only needed one default gateway on the data network (so users could reach Netsight 1st nic) as the switch management addresses were all on the same VLAN as the Netsight 2nd Nic.

I thought I documented the process but I cannot find it right now, and I just searched the web and was able to find the commands fairly easily.

Good Luck!

Thank you sir, I knew this way already.
But it does not recommend by Extreme, so I didn't update the issue.
The NIC setting file was located as following path,

After add the 2nd NIC,
NetSight need to modify something to make those devices on 2nd NIC can be searched with interface summary, compass.

Update the issue for you~
