Several VLANs need to be configured on the switches to separate traffic for the different hardware and integrate

DHCP properly on the system.
The default management switch is Arista DCS-7010T-48-F.

1) Up to 4 interfaces per rack for PDUs and switches management
2) Up to 4 interfaces per rack for server management interfaces
3) Up to 4 interfaces per rack for server facing BMCs and gateways
4) Up to 16 interfaces per rack for combined IPU-M2000 Gateway and BMC
5) Up to 16 interfaces per rack for BMC only connection (future option)
