The desired state of the user network interface. When a managed
system initializes, all user network interfaces start with down(2)
state. The testing(3)state indicates that no operational packets
can be passed. As a result of either explicit management action or
per configuration information retained by the managed system,
h3cEponUniAdminStatus is then changed to either the up(1) or
testing(3) states (or remains in the down(2) state).
