The tenant management MAC addresses do not originate from the chassis-wide management pool. They are software-generated MAC addresses. Though unlikely, this randomly allocated MAC address might collide with an existing MAC address in the tenant management network. This can result in unexpected and erratic network behavior for the tenant and for the external entity that has the same MAC address.
A tenant or external entity with the same MAC as the tenant could experience intermittent network issues on the management network, including tenant startup failure.
-- Start up a tenant. -- The system assigns a random management port. -- The random management port has a MAC address that already exists in the network.
To have the system generate a new MAC address: toggle the tenant's running state to Provisioned and back to Deployed. Note: If the new MAC address also conflicts with an existing MAC address, you must perform these steps again.
