Set up a profile with two physical interface

[Songyu Zhang]

Hi admins,

I recently starts to use the node type r7525. It have two physical NICs and suppose to have two physical ports able to be used, but when I use the `small-lan` profile, only one physical link shows up, other physical ports have `no-carrier`.

How should I enable two from two NIC interfaces for experiment use?

Maybe I should create a dedicated profile for this purpose?

Thanks

The "small-lan" profile only creates a single link on each node, thus only
one interface on each node is activated. To make both interfaces useable,
you have to have two links declared on the node in your profile.
A simple example is to connect two nodes with two links similar to this
profile:

https://www.cloudlab.us/p/PortalProfiles/multi-link

Since you want each profile topology link to have its own interface, you
would need to copy this profile and comment out the use of
"link_multiplexing" links. To make sure you get the node type you want,
you will also need to specify the hardware type of each node like:

node.hardware_type = "r7525"

Hi Mike,

Thanks for your prompt reply.

I viewed the source of the "multi-link" profile and it would declare two nodes explicitely and declare two links with the two nodes as member.

So I wonder if I can use multiple nodes like in "small-lan" profile (otherwise I have to create a profile for every node number I potentially would use) and have two links among them (by include all nodes in the members list `request.Link(members = [node1, node2])`).

Or if there are some documentation about the profile creation package, it would be better.

Thanks

Well, then maybe copy and modify the "small-lan" profile to add a second
lan to which you add a second interface of every node.
