Using this OID with SNMP

At least one MIB declaration places this object in a table row. A value belongs to a row instance; its suffix depends on the row's INDEX or AUGMENTS definition. The index encoding is not inferred here.

Published row index: ifMainIndex.

Replace the placeholders with your connection and authentication options. Available permissions and device support can differ from the MIB.

Properties come from available MIB definitions. Actual device support and access can differ. See source records below for original files and qualifications.

         DESCRIPTION
            "The current operational state of the interface.
            The testing (3) state indicates that no operational
            packets can be passed - this state is not supported
            currently. 
            
            If ifMainAdminStatus is down (2)
            then ifMainOperStatus would be down (2). If
            ifMainAdminStatus is changed to up (1) then
            ifMainOperStatus should change to up (1) if the
            interface is ready to transmit and receive
            work traffic; it should change to dormant (5)
            the interface is waiting for external actions
            (such as a serial line waiting for an incoming
            connection); it should change to lowerLayerDown(7)
            state if it cannot be made up as the interface sub-layer
            below it is down; 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.
            
            The status unknown(4) is shown when it is not possible
            to determine the exact status of the interface - e.g.
            the interface sub-layer is performing negotiations - 
            during this period the interface is not up but at the
            same time, it is not a fault condition and hence it
            cannot be shown as down - in such periods the status
            is shown as unknown.
            
            This object has the semantics of the ifOperStatus of the
            standard ifTable."
