Chapter 8 Industry-Standard Management Information Base IF-MIB 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 } ifAlias OBJECT-TYPE 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 } ifCounterDiscontinuityTime OBJECT-TYPE 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. ::= { ifXEntry 19 } Interface Stack Group Implementation of this group is optional, but strongly recommended for all systems. ifStackTable OBJECT-TYPE SYNTAX Sequence of IfStackEntry OL-22523-01 Cisco Unified Communications Manager Managed Services Guide 8-121
