| Description | The service state of the interface. Some but not all
interfaces, e.g., those on hardware modules with a
capability of supporting shared resources, can have
their state changed to 'outOfService'. Examples of
such shared resources include speed/bandwidth and
buffer memory. Shared resources include the values
of the following objects:
fcIfAdminSpeed,
fcIfAdminMode,
fcIfPortRateMode,
fcIfAdminRxBbCredit,
fcIfAdminRxBbCreditModeISL,
fcIfAdminRxBbCreditModeFx,
fcIfAdminRxBbCreditExtended,
fcIfAdminRxPerfBuffer.
When an attempt is made to change a particular
interface's value for this object to 'outOfService':
- if the interface's ifAdminStatus is 'up' or if the
interface is a part of a Port channel, then the
change to the value of this object is rejected.
- if the interface's value of this object is
successfully changed to 'outOfService', then each
and every user-configured parameter value of the
above-listed shared resource objects for that
interface is set to its default value.
When an interface is in the 'outOfService' state then:
- the interface is not operational and no packets
can be passed,
- the interface's shared resource objects can not be
configured to non-default values,
- the interface cannot be added to a port channel.
- the interface cannot be involved in a port swap
(using cficonPortSwapTable in CISCO-FICON-MIB).
- ifAdminStatus in IF-MIB cannot be changed to 'up'
state.
- other interface objects are not affected.
Changing the value of this object on one interface to
'outOfService' does not affect the functionality of any
other interface.
When an attempt is made to change a particular interface's
value for this object to 'inService', the attempt is
rejected if necessary shared resources are unavailable. |
