Object

column mandatory r/w RFC1213-MIBDisplayString
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.
