The value is a sum. This sum initially takes the value zero. Then, for
each technology, T, that the port supports, 2 raised to (T - 1) is added
to the sum. For example, a port that supports 1000BASE-TFD (T = 18) and
1000BASE-T (T = 17) would return a value of 196608
((2 ^ (18 - 1)) + (2 ^ (17 - 1))).
For ports supporting Auto-Negotiation, values should be calculated
as follows:

The value is a sum. This sum initially takes the value zero. Then, for
each technology, T, that the port is advertising, 2 raised to (T - 1)
is added to the sum. For example, a port that advertises 1000BASE-TFD

((2 ^ (18 - 1)) + (2 ^ (17 - 1))).
Values for T are limited to technologies supported by the hardware as

A successful set operation will result in immediate link re-negotiation
if Auto-Negotiation is enabled on this port, as specified by
ctAutoNegAdminStatus. A set of this object to a value containing bits
that are not supported by the hardware will be successful, but, the port
will only advertise values which are the logical AND of the set value and
ctAutoNegLocalTechnologyAbility.
Note: this re-negotiation will in every case cause temporary link loss
during the link re-negotiation. If set to a value that is incompatible
with ctAutoNegLocalTechnologyAbility, link negotiation will not
be successful and will cause permanent link loss.

partner.
The value is a sum. This sum initially takes the value zero. Then, for
each technology, T, that the link partner supports, 2 raised to (T - 1)
is added to the sum. For example, a link partner advertising
1000BASE-TFD (T = 18) and 1000BASE-T (T = 17) would return a value
of 196608 ((2 ^ (18 - 1)) + (2 ^ (17 - 1))).

| ctFlowCtlHalfDuplexAdminStatus |
.1.3.6.1.4.1.52.4.1.2.4.2.2.1.1.1 |
|
The administrative status requested by management for back pressure
on this port. Back pressure is a collision based flow control mechanism
used in half duplex configurations. The value of enabled(1) indicates
that back pressure should be enabled on this port if the port is in half
duplex. The value of disable(2) indicates that back pressure should be
disabled on this port.
|
| ctFlowCtlHalfDuplexOperStatus |
.1.3.6.1.4.1.52.4.1.2.4.2.2.1.1.2 |

.1.3.6.1.4.1.52.4.1.2.4.2.2.1.1.3 |

This indicates the frame based modes of full duplex flow control for this
port.
The value is a sum. This sum initially takes the value zero. Then, for
each mode, M, that the port supports, 2 raised to (M - 1) is added to
the sum. For example, a port that supports Symmetric (M= 2),
AsymmetricRX (M = 3) and AsymmetricTx (M = 4) would return a value
of 14 ((2 ^ (2 - 1)) + (2 ^ (3 - 1)) + (2 ^ (4 - 1))).
Speed values should be calculated as follows:

| ctFlowCtlPauseAdminStatus |
.1.3.6.1.4.1.52.4.1.2.4.2.2.1.1.4 |
|
The administrative status requested by management for frame based
flow control on this port. For 10 Mb and 100 Mb ports the value of
symmetric(1) indicates that if Auto-Negotiation is supported for this
port, that the FDX PAUSE bit in the ctAutoNegLocalTechnologyAbility will
be set, further indicating that the port supports full duplex flow
control. For 1000 Mb the value of symmetric(1) indicates that if
Auto-Negotiation is supported for this port, that the FDX SPAUSE
bit in the ctAutoNegLocalTechnologyAbility will be set, further
indicating that the port supports symmetric frame based flow control.
In all cases a set of symmetric(1) will cause the port to interpret
received PAUSE frames and allow the port to transmit PAUSE frames when
necessary. A set of a value of symmetric(1) is limited to those ports
that support symmetric frame based flow control as specified by
ctEtherSupportedPauseModes.
The value of asymmetricRx(2) indicates that if Auto-Negotiation is
supported for this port, that the FDX BPAUSE bit in the
ctAutoNegLocalTechnologyAbility will be set, further
indicating that the port supports asymmetric receive frame based flow
control. In all cases a set of asymmetricRx(2) will cause the port to
interpret received PAUSE frames and disallow the port to transmit PAUSE
frames. A set of a value of asymmetricRx(2) is limited to those ports
that support asymmetricRx frame based flow control as specified by
ctEtherSupportedPauseModes.
The value of asymmetricTx(3) indicates that if Auto-Negotiation is
supported for this port, that the FDX APAUSE bit in the
ctAutoNegLocalTechnologyAbility will be set, further indicating that the
port supports asymmetric transmit frame based flow control. In all cases
a set of asymmetricTx(3) will cause the port to ignore PAUSE frames and
allow the port to transmit PAUSE frames when necessary. A set of a value
of asymmetricTx(3) is limited to those ports that support asymmetricTx
frame based flow control as specified by ctEtherSupportedPauseModes.
The value of disabled(4) indicates that if Auto-Negotiation is supported
for this port, that the FDX PAUSE, FDX APAUSE, FDX SPAUSE and FDX BPAUSE
bits in the ctAutoNegLocalTechnologyAbility will be cleared, further
indicating that the port does not support frame based flow control. In
all cases a set of disable(2) will cause the port to ignore received
PAUSE frames and to disallow the port to transmit PAUSE frames.
The value of autonegotiate(5) indicates that if Auto-Negotiation is
supported for this port, and the hardware supports the ability to
advertise PAUSE capability, that the maximum flow control capabilities
of the hardware are to be reflected in the PAUSE bits of
ctAutoNegLocalTechnologyAbility. The ports flow control operational
state will be determined by the results of Auto-Negotiation. If
Auto-Negotiation is not supported for this port, a set of
autonegotiate(5) will fail.
In all cases frame based flow control is only used for ports that
are in full duplex.

| ctFlowCtlPauseOperStatus |
.1.3.6.1.4.1.52.4.1.2.4.2.2.1.1.5 |
|
The current operational status of full duplex flow control
on this port. A value of unknown(5) will be returned for any port which
has a Pause Frame Admin Status of autonegotiate(5), as specified by
ctFlowCtlPauseAdminStatus, but is in an unknown Auto-Negotiation state.

A 2 octet, unsigned integer containing the length of time for which
the receiving station is requested to inhibit data frame transmission.
The pause time is measured in units of pause_quanta, equal to 512 bit
times of the particular implementation.
|
| ctFlowCtlRxPauseFrames |
.1.3.6.1.4.1.52.4.1.2.4.2.2.1.1.7 |

The number of pause frames received on this port.

.1.3.6.1.4.1.52.4.1.2.4.2.2.1.1.8 |

The number of pause frames transmitted from this port.
|
| ctEtherSupportedSpeed |
.1.3.6.1.4.1.52.4.1.2.4.2.3.1.1.1 |
|
This indicates the supported speeds for the port.
The value is a sum. This sum initially takes the value zero. Then, for
each speed, S, that the port supports, 2 raised to (S - 1) is added to
the sum. For example, a port that supports 10 Mb (S = 1) and 100 Mb
(S = 2) would return a value of 3 ((2 ^ (1 - 1)) + (2 ^ (2 - 1))).
Speed values should be calculated as follows:

.1.3.6.1.4.1.52.4.1.2.4.2.3.1.1.2 |
|
The administrative status requested by management for the speed of this
port. The value of tenmegabit(2) indicates that if Auto-Negotiation
is disabled for this port, that the port will operate at a speed of
10 megabits per second, provided that the port supports that speed,
as specified by ctEtherSupportedSpeed.
The value of hundredmegabit(3) indicates that if Auto-Negotiation
is disabled for this port, that the port will operate at a speed of
100 megabits per second, provided that the port supports that speed,
as specified by ctEtherSupportedSpeed.
The value of gigabit(4) indicates that if Auto-Negotiation
is disabled for this port, that the port will operate at a speed of
1000 megabits per second, provided that the port supports that speed,
as specified by ctEtherSupportedSpeed.
In all cases, if the value specified does not indicate a speed that
the port supports the set will fail.

A value of halfduplex(1) indicates that the port only supports
half duplex operation. A value of fullduplex(2) indicates that

halfandfullduplex(3) indicates that the port supports both
half and full duplex operation.

.1.3.6.1.4.1.52.4.1.2.4.2.3.1.1.5 |

is disabled for this port, that the port will operate in half duplex,
provided that the port supports half duplex, as specified by
ctEtherSupportedDuplex.
The value of fullduplex(3) indicates that if Auto-Negotiation
is disabled for this port, that the port will operate in full duplex,
