If necessary, you can replace your Cloud Foundation installation's network switches. Each rack in the installation has one management switch and two top-of-rack (ToR) switches. The whole installation also has two spine 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 spine switches must be from the same vendor, such as all Cisco switches or all Arista switches. Mixing and matching of switches is not supported.
