MIB: IF-MIB
The current operational state of the interface.
- The testing(3) state indicates that no operational packet scan be passed
- If ifAdminStatus is down(2) then ifOperStatus should be down(2)
- If ifAdminStatus is changed to up(1) then ifOperStatus should change to up(1) if the interface is ready to transmit and receive network traffic
- It should change todormant(5) if the interface is waiting for external actions (such as a serial line waiting for an incoming connection)
- It should remain in the down(2) state if and only if there is a fault that prevents it from going to the up(1) state
- It should remain in the notPresent(6) state if the interface has missing(typically, hardware) components.
