ctFastEthernetCtl OBJECT IDENTIFIER .1.3.6.1.4.1.52.4.1.2.9.1 |
IMPORTS Unknown .1.3.6.1.4.1.52.4.1.2.9.1 |
ctFastEthernetCtlTableProvides a list of definitions and control objects over 100Base-X
ports. SEQUENCE OF CtFastEthernetCtlEntry .1.3.6.1.4.1.52.4.1.2.9.1.1 |
ctFastEthernetCtlEntryDefines a particular entry containing objects pertaining to
definition and control over 100Base-X ports. CtFastEthernetCtlEntry .1.3.6.1.4.1.52.4.1.2.9.1.1.1 |
ctFastEthernetCtlInterfaceThe interface for which this fast ethernet information pertains.ro INTEGER .1.3.6.1.4.1.52.4.1.2.9.1.1.1.1 |
ctFastEthernetCtlPortGroupThe port group for which this fast ethernet information
pertains.ro INTEGER .1.3.6.1.4.1.52.4.1.2.9.1.1.1.2 |
ctFastEthernetCtlPortThe physical port for which this fast ethernet information pertains.ro INTEGER .1.3.6.1.4.1.52.4.1.2.9.1.1.1.3 |
ctFastEthernetLocalTechnologyAbilityThis indicates the technology ability of the local hardware.
The value of this object is the logical OR of all supported
technologies. Where each technology is given the values below:
other(1) Undefined, or ability not known
Auto-Negotiation(2) Auto-Negotiation
10BASE-T(8) 10BASE-T
10BASE-TFD(16) Full duplex 10BASE-T
100BASE-TX(32) 100BASE-TX
100BASE-TXFD(64) Full Duplex 100BASE-TX
100BASE-T4(128) 100BASE-T4
100BASE-FX(256) 100BASE-FX
100BASE-FXFD(512) Full Duplex 100Base-FX
For example a port which supported 100Base-TX(32), 100Base-TXFD(64),
and Auto-Negotiation(2) would have a value of 98(32 + 64 + 2).ro INTEGER .1.3.6.1.4.1.52.4.1.2.9.1.1.1.4 |
ctFastEthernetCurrentOperationalModeIndicates the current operational mode of this port.
The value of this object is the logical OR of current opertational
mode and how we arrived at that mode, whether it be by
Auto-Negotiation(2), Manual-Config(4) or default.
Where each mode is given the values below:
other(1) Initializing or no link, ability unknown
Auto-Negotiation(2) Auto-Negotiation/Parallel Detection
Manual-Config(4) Manually Configured
10BASE-T(8) 10BASE-T
10BASE-TFD(16) Full duplex 10BASE-T
100BASE-TX(32) 100BASE-TX
100BASE-TXFD(64) Full Duplex 100BASE-TX
100BASE-T4(128) 100BASE-T4
100Base-FX(256) 100Base-FX
100Base-FXFD(512) Full Duplex 100Base-FX
For example, a port operating at 100Base-TX(32) achieved through
Auto-Negotiation(2) would have a value of 34(32 + 2).
If the port was manually configured(4) for 100Base-TX(32) this object
would have a value of 36(32 + 4).
Values written to this object are limited to values read from
ctFastEthernetLocalTechnologyAbility, with the addition of
Manual-Config(4) but excluding other(1). Therefore if
ctFastEthernetLocalTechnologyAbility has a value of 98 writing a
value of 256 would result in an error. That is to say 100Base-FX
is not supported on this port.
A set to a value of Auto-Negotiation(2) will result in
auto-negotiation being enabled and will cause link re-negotiation.
Note: this re-negotiation will in every case cause temporary link loss
during the link re-negotiation. Any other set with Auto-Negotiation(2)
included will result in an error since you can not force an operational
mode and auto-negotiation at the same time.
A set to a value of Manual-Config(4) will result in auto-negotiation
being disabled but the port staying at its current operational mode
until device reset/power down at which time the port will come up
in default mode. A subsequent read will indicate only the current
operational mode achieved by default means.
A set to any other value (port is being manually configured) must
reflect a single ability. For example writing a value of 68 would
result in auto-negotiation being disabled and the port being manually
configured(4) for 100Base-TXFD(64). However a write of 100 would
result in an error.rw INTEGER .1.3.6.1.4.1.52.4.1.2.9.1.1.1.5 |
ctFastEthernetAdvertisedTechnologyAbilityIndicates the advertised ability of the local hardware, but only
becomes active on ports that have auto-negotiation enabled.
For example a port which will advertise 100Base-TX(32) and
100Base-TXFD(64) ablilities would have a value of 96(32 + 64). A port
that does not support auto-negotiation will be read as other(1).
Values written to this object are limited to values read from
ctFastEthernetLocalTechnologyAbility, excluding other(1) and
Auto-Negotiation(2). Therefore if ctFastEthernetLocalTechnologyAbility
has a value of 98 writing a value of 128 would result in an error. That
is to say 100Base-T4 is not supported on this port. Furthermore, if
ctFastEthernetLocalTechnologyAbility has a value that does not include
Auto-Negotiation(2), writing any value will result in an error. That is
to say that this port does not support Auto-Negotiation and therefore
does not support ctFastEthernetAdvertisedTechnologyAbility.
A successful set operation will result in immediate link re-negotiation
if ctFastEthernetCurrentOperationalMode has a value that includes
Auto-Negotiation(2)(meaning Auto-negotiation is enabled).
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 ctFastEthernetReceivedTechnologyAbility, link negotiation will not
be successful and will cause permanent link loss.rw INTEGER .1.3.6.1.4.1.52.4.1.2.9.1.1.1.6 |
ctFastEthernetReceivedTechnologyAbilityIndicates the advertised ability of the remote hardware, or link
partner. The value of this object is the logical OR of all supported
technologies. Where each technology is given the values below:
other(1) Undefined
Auto-Negotiation(2) Auto-Negotiation/Parallel Detection
Not-Detected(4) Link Partner does not support Auto-Negotiation
10BASE-T(8) 10BASE-T
10BASE-TFD(16) Full duplex 10BASE-T
100BASE-TX(32) 100BASE-TX as defined in clause 25
100BASE-TXFD(64) Full Duplex 100BASE-TX
100BASE-T4(128) 100BASE-T4 as defined in clause 23
100Base-FX(256) 100Base-FX
100Base-FXFD(512) Full Duplex 100Base-FX
For example a port which supports 100Base-TX(32), 100Base-TXFD(64),
would have a value of 98(32 + 64 + Auto-Negotiation(2)).
A read should always include Auto-Negotiation(2), unless the link
partner does not support auto-negotiation, at which time the value
will be Not-Detected(4) or auto-negotiation is disabled(or not
supported) for this port at which time the value will be other(1).ro INTEGER .1.3.6.1.4.1.52.4.1.2.9.1.1.1.7 |
