Object
column

Integer32
Indicates 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.
