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.
