multiIfMainOperStatus OBJECT-TYPE
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).}
MAX-ACCESS read-only
STATUS current
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."
