DESCRIPTION
"The MIB module describes a generic solution
to model alarms and to store the current list
of active alarms.

Copyright (C) The Internet Society (2004).  The
initial version of this MIB module was published
in RFC 3877.  For full legal notices see the RFC
itself.  Supplementary information may be available on:

ResourceId ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"A unique identifier for this resource.

The type of the resource can be determined by looking
at the OID that describes the resource.

Resources must be identified in a consistent manner.
For example, if this resource is an interface, this
object MUST point to an ifIndex and if this resource
is a physical entity [RFC2737], then this MUST point
to an entPhysicalDescr, given that entPhysicalIndex
is not accessible.  In general, the value is the
name of the instance of the first accessible columnar
object in the conceptual row of a table that is
meaningful for this resource type, which SHOULD
be defined in an IETF standard MIB."
