It is recommended that values are assigned contig- uously starting from 1. The value for each interface sub-layer must remain constant at least from one re- initialization of the entity's network management system to the next re-initialization." ifAdminStatus SYNTAX INTEGER { up(1), -- ready to pass packets down(2), testing(3) -- in some test mode } DESCRIPTION "The desired state of the interface. The testing(3) state indicates that no operational packets can be passed. When a managed system initializes, all interfaces start with ifAdminStatus in the down(2) state. As a result of ei- ther explicit management action or per configuration information retained by the managed system, ifAdminStatus is then changed to either the up(1) or testing(3) states (or remains in the down(2) state)." ifOperStatus SYNTAX INTEGER { up(1), -- ready to pass packets down(2), testing(3), -- in some test mode unknown(4), -- status can not be determined -- for some reason. dormant(5), notPresent(6), -- some component is missing lowerLayerDown(7) -- down due to state of -- lower-layer interface(s) } DESCRIPTION "The current operational state of the interface. The testing(3) state indicates that no operational packets can 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 to dormant(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." 33472 Rev.
