RFC 1065 SMI August 1988

Status:

mandatory.

Each instance of this object type comprises information represented

by instances of the former three object types. An object type

defined in this way is called a list.

Similarly, tables can be formed by aggregations of a list type. For

example, a fifth object type might also be defined in the MIB:

OBJECT:

------

atTable { at 1 }

Syntax:

SEQUENCE OF AtEntry

Definition:

The address translation table.

Access:

read-write.

Status:

mandatory.

such that each instance of the atTable object comprises information

represented by the set of atEntry object types that collectively

constitute a given atTable object instance, that is, a given address

translation table.

Consider how one might refer to a simple object within a table.

Continuing with the previous example, one might name the object type

{ atPhysAddress }

and specify, using a protocol-specific mechanism, the object instance

{ atNetAddress } = { internet "10.0.0.52" }

This pairing of object type and object instance would refer to all

instances of atPhysAddress which are part of any entry in some

address translation table for which the associated atNetAddress value

is { internet "10.0.0.52" }.

To continue with this example, consider how one might refer to an

aggregate object (list) within a table. Naming the object type

{ atEntry }

and specifying, using a protocol-specific mechanism, the object

instance

{ atNetAddress } = { internet "10.0.0.52" }

refers to all instances of entries in the table for which the

associated atNetAddress value is { internet "10.0.0.52" }.

Each management protocol must provide a mechanism for accessing

simple (non-aggregate) object types. Each management protocol

specifies whether or not it supports access to aggregate object

types. Further, the protocol must specify which instances are
