ifMtu { ifEntry 4 } read-only “The size of the largest
datagram which can be
sent/received on the
interface, specified in
octets. For interfaces that
are used for transmitting
network datagrams, this is
the size of the largest
network datagram that can
be sent on the interface.” Returns one of the following integer
values:
1500 - returned for the Ethernet
interface.
2000 - returned for the Token Ring.
0 - returned for all other interfaces.
ifSpeed { ifEntry 5 } read-only “An estimate of the
interface's current
bandwidth in bits per
second. For interfaces
which do not vary in
bandwidth or for those
where no accurate
estimation can be made,
this object should contain
the nominal bandwidth.” Returns the rate at which the interface
is running.
ifPhysAddress { ifEntry 6 } read-only “The interface’s address at
the protocol layer
immediately ‘below’ the
network layer in the
protocol stack. For
interfaces which do not
have such an address (e.g.,
a serial line), this should
contain an octet string of
zero length.” Returns an octet string of zero length
for all interfaces except the E/TR
Ethernet/TokenRing interface, which
returns the physical address of the
unit.
ifAdminStatus { ifEntry 7 } read-write “The desired state of the
interface. The testing(3)
state indicates that no
operational packets can be
passed.” Returns user selected value. Defaults
to up(1). up(1) - user sets
to signify the
interface is active,
and does not have
a testing status.
down(2) - user
sets to signify the
interface is not
enabled or in an
alarm condition.
testing(3) - user
sets to signify the
interface has a
test loop or BERT
active.
ifOperStatus { ifEntry 8 } read-only “The current operational
state of the interface. The
testing(3) state indicates
that no operational packets
can be passed.” up(1) - returned if the interface is
active, and does not have a testing
status.
down(2) - returned if the interface is
not enabled or in an alarm condition.
testing(3) - returned if the interface
has a test loop or BERT active.
