After rebooting a tenant, the tenant might receive some erratic VLAN assignment requests, but the VLANs are not associated with this tenant. This spurious VLAN assignment may impact traffic.

Impact

Application traffic through the chassis could be impacted.

Conditions

1. A tenant is created without an assigned VLAN 2. Reboot the blade that tenant is assigned to The second step is not required every time, but it is triggered due to the first step.

Workaround

There are 2 workarounds: 1. Assign VLAN(s) to the tenant which does not have assigned VLANs and reboot all the blades of this tenant 2. Assign VLAN(s) to the tenant which does not have assigned VLAN and run 'docker restart of API_SERVICE_GW container' on all blades

Fix Information

When a tenant is not configured with any VLANs, the tenant will no longer receive incorrect VLANs when a blade is rebooted.
