Assessment Title
Rule Text
The vCenter Server must not configure all port groups to VLAN values reserved by upstream physical switches.
Description
Discussion Text
Certain physical switches reserve certain VLAN IDs for internal purposes and often disallow traffic configured to these values. For example, Cisco Catalyst switches typically reserve VLANs 1001–1024 and 4094, while Nexus switches typically reserve 3968–4047 and 4094.
Check with the documentation for the specific switch. Using a reserved VLAN might result in a denial of service on the network.
