Hi David,
xCAT does provide the support for cumulus switch provision and configuration, please find the Doc on https://xcat-docs.readthedocs.io/en/latest/advanced/networks/onie_switches/index.html

the cluster nodes. I have the xCAT master attached to that net on interface em3.
you might need to add em3 and em1 to site.dhcpinterfaces.
[root@boston36 ~]# tabdump -d site|grep dhcpinterf -A6
dhcpinterfaces: The network interfaces DHCP should listen on. If it is the same for all nodes, use a comma-separated list of the NICs. To specify different NICs for different nodes, use the format: "xcatmn|eth1,eth2;service|bond0",
where xcatmn is the name of the management node, DHCP should listen on the eth1 and eth2 interfaces. All the nodes in group 'service' should listen on the 'bond0' interface.

and well define the 2 networks in networks table.
Please feel free to ask us if any issue.

Subject: [xcat-user] provisioning CumulusLinux TOR switches with xCAT
Date: Sun, Mar 3, 2019 7:40 AM
Currently running xCAT 2.13.4. I've been manually installing and configuring
our CumulusLinux based switches, and it's getting old.
I've got more than a dozen deployed, and now they want OS upgrades....
I noticed some online docs about managing switches with xCAT, but nothing specific to cumulus linux.
I'd like to use the xcat httpd to serve the images, and maybe use xdcp and xdsh to do the configuration
and license installation. However I don't want to mess up the rest of the cluster.
The biggest issue is that the TOR switch management ports are on a completely different network from
the cluster nodes. I have the xCAT master attached to that net on interface em3. I'd like to add a small dynamic
DHCP range on that 10.4.y.z network while nodes continue to boot and install on the existing 172.20.p.q (em1) network.
Also need to have the web server listening on em3.
Thanks,
-- ddj
