| DESCRIPTION "This object is used to configure the default |
| administrative PAUSE mode for this interface. |
| |
| This object represents the |
| administratively-configured PAUSE mode for this |
| interface. If auto-negotiation is not enabled |
| or is not implemented for the active MAU |
| attached to this interface, the value of this |
| object determines the operational PAUSE mode |
| of the interface whenever it is operating in |
| full-duplex mode. In this case, a set to this |
| object will force the interface into the |
| specified mode. |
| |
| If auto-negotiation is implemented and enabled |
| for the MAU attached to this interface, the |
| PAUSE mode for this interface is determined by |
| auto-negotiation, and the value of this object |
| denotes the mode to which the interface will |
| automatically revert if/when auto-negotiation is |
| later disabled. Note that when auto-negotiation |
| is running, administrative control of the PAUSE |
| mode may be accomplished using the |
| ifMauAutoNegCapAdvertisedBits object in the |
| MAU-MIB. |
| |
| Note that the value of this object is ignored |
| when the interface is not operating in |
| full-duplex mode. |
| |
| An attempt to set this object to |
| 'enabledXmit(2)' or 'enabledRcv(3)' will fail |
| on interfaces that do not support operation |
| at greater than 100 Mb/s." |

| STATUS current |
| DESCRIPTION "The Time-Domain Reflectometry (TDR) test is |
| specific to ethernet-like interfaces of type |
| 10Base5 and 10Base2. The TDR value may be |
| useful in determining the approximate distance |
| to a cable fault. It is advisable to repeat |
| this test to check for a consistent resulting |
| TDR value, to verify that there is a fault. |
| |
| A TDR test returns as its result the time |
| interval, measured in 10 MHz ticks or 100 nsec |
| units, between the start of TDR test |
| transmission and the subsequent detection of a |
| collision or deassertion of carrier. On |
| successful completion of a TDR test, the result |
| is stored as the value of an appropriate |
| instance of an appropriate vendor specific MIB |
| object, and the OBJECT IDENTIFIER of that |
| instance is stored in the appropriate instance |
| of the appropriate test result code object |
| (thereby indicating where the result has been |
| stored)." |

| only be executed if the interface is offline. |
| Once the test has completed, the MAC chip should |
| be reinitialized for network operation, but it |
| should remain offline. |
| |
| If an error occurs during a test, the |
| appropriate test result object will be set |
| to indicate a failure. The two OBJECT |
| IDENTIFIER values dot3ErrorInitError and |
