Description:

hubPortAdminState OBJECT-TYPE
SYNTAX INTEGER {enabled(1), disabled(2)}
ACCESS read-write
STATUS mandatory
DESCRIPTION
"Setting this object to disabled(2) disables the
port. A disabled port neither transmits nor
receives. Once disabled, a port must be
explicitly enabled to restore operation. A port
which is disabled when power is lost or when a
reset is exerted shall remain disabled when normal
operation resumes.
The admin status takes precedence over auto-
partition and functionally operates between the
auto-partition mechanism and the AUI/PMA.
Setting this object to enabled(1) enables the port
and exerts a BEGIN on the port's auto-partition
state machine.
Note: 1. In effect, when a port is disabled via this object or
rptrPortAdminStatus object, the value of
hubPortPartitionStatus and rptrPortAutoPartitionState
for that port is frozen until the port is next enabled.
When the port becomes enabled, the hubPortPartitionStatus
and rptrPortAutoPartitionState becomes notAutoPartitioned(1),
regardless of its pre-disabling state.
2. When port administration control is requested and
the specified port is a member of redundant link pairs,
the following rule should be followed:
a). the port is the active link of a redundant link pair:
If admin disabled(2) requested, the port will be disabled.
The status of that redundant pair shall be set to
suspended(3) to indicate that active link has been disabled.
If admin enabled(2) requested, the port will be enabled.
The status of that redundant pair shall be returned to
enabled(2) if its current status is suspended(3).
b). the port is not the active link of a redundant link pair:
The port administration control will be rejected."
