Interface Stack Group

Implementation of this group is optional, but strongly recommended for all systems.
ifStackTable OBJECT-TYPE
OL-22523-01
STATUS current
DESCRIPTION
This object has the value 'true(1)' if the interface sublayer has a physical connector and the value
'false(2)' otherwise.
::= { ifXEntry 17 }
SYNTAX DisplayString (SIZE(0..64))
MAX-ACCESS read-write
STATUS current
DESCRIPTION
This object is an alias name for the interface as specified by a network manager, and provides a
non-volatile handle for the interface.
On the first instantiation of an interface, the value of ifAlias associated with that interface is the
zero-length string. As and when a value is written into an instance of ifAlias through a network
management set operation, then the agent must retain the supplied value in the ifAlias instance
associated with the same interface for as long as that interface remains instantiated, including across
all re-initializations/reboots of the network management system, including those which result in a
change of the interface's ifIndex value.
An example of the value which a network manager might store in this object for a WAN interface is
the (Telco's) circuit number/identifier of the interface.
Some agents may support write-access only for interfaces having particular values of ifType. An
agent which supports write access to this object is required to keep the value in non-volatile storage,
but it may limit the length of new values depending on how much storage is already occupied by the
current values for other interfaces.
::= { ifXEntry 18 }
SYNTAX TimeStamp
MAX-ACCESS read-only
STATUS current
DESCRIPTION
The value of sysUpTime on the most recent occasion at which any one or more of this interface's
counters suffered a discontinuity. The relevant counters are the specific instances associated with
this interface of any Counter32 or Counter64 object contained in the ifTable or ifXTable. If no such
discontinuities have occurred since the last re-initialization of the local management subsystem,
then this object contains a zero value.
