Symptoms
An F5OS Tenant at startup may print a log to indicate that a VLAN configured on the Tenant has not been assigned by the hypervisor.
For example:
warning mcpd[7929]: 01071323:4: Vlan (/Common/vlan-999:999) is configured, but NOT on hypervisor allowed list.
This alerts the administrator to a possible problem in the hypervisor or tenant configuration. The log can appear at startup, complicating troubleshooting and leading the administrator to believe a problem exists when it does not.
Impact
This is benign but misleading.
Conditions
This is often noticed at startup, but may also be observed when:
-- Adding vlans
-- Restarting chmand (bigstart restart chmand)
-- Other configuration changes on the F5OS hypervisor that may affect the tenant (e.g. disabling/enabling interfaces or changing trunk configurations)
Workaround
The administrator can verify the log is false by checking the Tenant configuration (show tenants) on the F5OS hypervisor.
