If necessary, you can replace your Cloud Foundation system's network switches. Each rack in the system has one management switch and two top-of-rack (ToR) switches. The whole system also has two inter-rack switches.
You can also restore a switch to a configuration backup previously created.
The replacement switches must be from the supported list in the
VMware Cloud Foundation Compatibility Guide
. Your ToR and inter-rack switches must be from the same vendor, such as all Dell EMC Networking switches, Cisco switches, or all Arista switches. Mixing and matching of switches is not supported.
