sysDescr OBJECT-TYPE
SYNTAX DisplayString (SIZE (0..255))
ACCESS read-only
STATUS mandatory
DESCRIPTION
"A textual description of the entity. This value
should include the full name and version
identification of the system's hardware type,
software operating-system, and networking
software. It is mandatory that this only contain
printable ASCII characters."
::= { system 1 }
sysObjectID OBJECT-TYPE
SYNTAX OBJECT IDENTIFIER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The vendor's authoritative identification of the
network management subsystem contained in the
entity. This value is allocated within the SMI
enterprises subtree (1.3.6.1.4.1) and provides an
easy and unambiguous means for determining `what
kind of box' is being managed. For example, if
vendor `Flintstones, Inc.' was assigned the
subtree 1.3.6.1.4.1.4242, it could assign the
identifier 1.3.6.1.4.1.4242.1.1 to its `Fred
Router'."
::= { system 2 }

SYNTAX TimeTicks
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The time (in hundredths of a second) since the
network management portion of the system was last
re-initialized."
::= { system 3 }
sysContact OBJECT-TYPE
SYNTAX DisplayString (SIZE (0..255))
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The textual identification of the contact person
for this managed node, together with information
on how to contact this person."
::= { system 4 }
sysName OBJECT-TYPE
SYNTAX DisplayString (SIZE (0..255))
ACCESS read-write
STATUS mandatory
DESCRIPTION
"An administratively-assigned name for this
managed node. By convention, this is the node's
fully-qualified domain name."
::= { system 5 }
sysLocation OBJECT-TYPE
SYNTAX DisplayString (SIZE (0..255))
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The physical location of this node (e.g.,
`telephone closet, 3rd floor')."
::= { system 6 }
sysServices OBJECT-TYPE
SYNTAX INTEGER (0..127)
ACCESS read-only
STATUS mandatory
DESCRIPTION
"A value which indicates the set of services that
this entity primarily offers.
The value is a sum. This sum initially takes the
value zero, Then, for each layer, L, in the range
1 through 7, that this node performs transactions
for, 2 raised to (L - 1) is added to the sum. For
example, a node which performs primarily routing
functions would have a value of 4 (2^(3-1)). In
contrast, a node which is a host offering
application services would have a value of 72
(2^(4-1) + 2^(7-1)). Note that in the context of
the Internet suite of protocols, values should be
calculated accordingly:
layer functionality
1 physical (e.g., repeaters)
2 datalink/subnetwork (e.g., bridges)
3 internet (e.g., IP gateways)
4 end-to-end (e.g., IP hosts)
7 applications (e.g., mail relays)
For systems including OSI protocols, layers 5 and
6 may also be counted."

-- the Interfaces group
-- Implementation of the Interfaces group is mandatory for
-- all systems.
ifNumber OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The number of network interfaces (regardless of
their current state) present on this system."
::= { interfaces 1 }
-- the Interfaces table
-- The Interfaces table contains information on the entity's
-- interfaces. Each interface is thought of as being
-- attached to a `subnetwork'. Note that this term should
-- not be confused with `subnet' which refers to an
-- addressing partitioning scheme used in the Internet suite
-- of protocols.
ifTable OBJECT-TYPE
SYNTAX SEQUENCE OF IfEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"A list of interface entries. The number of
entries is given by the value of ifNumber."

implementation of ASN.1 and BER must be able to
generate and recognize this value."
::= { ifEntry 22 }
-- the Address Translation group
-- Implementation of the Address Translation group is
-- mandatory for all systems. Note however that this group
-- is deprecated by MIB-II. That is, it is being included
-- solely for compatibility with MIB-I nodes, and will most
-- likely be excluded from MIB-III nodes. From MIB-II and
-- onwards, each network protocol group contains its own
-- address translation tables.
-- The Address Translation group contains one table which is
-- the union across all interfaces of the translation tables
-- for converting a NetworkAddress (e.g., an IP address) into
-- a subnetwork-specific address. For lack of a better term,
-- this document refers to such a subnetwork-specific address
-- as a `physical' address.
-- Examples of such translation tables are: for broadcast
-- media where ARP is in use, the translation table is
-- equivalent to the ARP cache; or, on an X.25 network where
-- non-algorithmic translation to X.121 addresses is
-- required, the translation table contains the
-- NetworkAddress to X.121 address equivalences.

DESCRIPTION
"The Address Translation tables contain the
NetworkAddress to `physical' address equivalences.
Some interfaces do not use translation tables for
determining address equivalences (e.g., DDN-X.25
has an algorithmic method); if all interfaces are
of this type, then the Address Translation table
is empty, i.e., has zero entries."

DESCRIPTION
"The interface on which this entry's equivalence

particular value of this index is the same
interface as identified by the same value of
ifIndex."
::= { atEntry 1 }
atPhysAddress OBJECT-TYPE
SYNTAX PhysAddress
ACCESS read-write
STATUS deprecated
DESCRIPTION
"The media-dependent `physical' address.
Setting this object to a null string (one of zero
length) has the effect of invaliding the
corresponding entry in the atTable object. That
is, it effectively dissasociates the interface
identified with said entry from the mapping
identified with said entry. It is an
implementation-specific matter as to whether the
agent removes an invalidated entry from the table.
Accordingly, management stations must be prepared
to receive tabular information from agents that
corresponds to entries not currently in use.
Proper interpretation of such entries requires
examination of the relevant atPhysAddress object."

DESCRIPTION
"The indication of whether this entity is acting
as an IP gateway in respect to the forwarding of
datagrams received by, but not addressed to, this
entity. IP gateways forward datagrams. IP hosts
do not (except those source-routed via the host).
Note that for some managed nodes, this object may
take on only a subset of the values possible.
Accordingly, it is appropriate for an agent to
return a `badValue' response if a management
station attempts to change this object to an
inappropriate value."

SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The number of input datagrams discarded because
the IP address in their IP header's destination
field was not a valid address to be received at
this entity. This count includes invalid
addresses (e.g., 0.0.0.0) and addresses of
unsupported Classes (e.g., Class E). For entities
which are not IP Gateways and therefore do not
forward datagrams, this counter includes datagrams
discarded because the destination address was not
