- ifExtnsTestType OBJECT-TYPE
- SYNTAX OBJECT IDENTIFIER
- ACCESS read-write
- STATUS mandatory
- DESCRIPTION
- "A control variable used to start and stop
- operator-initiated interface tests.
- Most OBJECT IDENTIFIER values assigned
- to tests are defined elsewhere, in associ-
- ation with specific types of interface.
- However, this document assigns a value for
- a full-duplex loopback test, and defines the
- special meanings of the subject identifier:
- noTest OBJECT IDENTIFIER ::= { 0 0 }
- When the value noTest is written to this
- object, no action is taken unless a test is
- in progress, in which case the test is
- aborted. Writing any other value to this
- object is only valid when no test is
- currently in progress, in which case the
- indicated test is initiated.
- Note that noTest is a syntactically valid
- object identifier, and any conformant
- implementation of ASN.1 and BER must be able
- to generate and recognize this value.
- When read, this object always returns
- the most recent value that ifExtnsTestType
- was set to. If it has not been set since
- the last initialization of the network
- management subsystem on the agent, a value
- of noTest is returned."

- aborted(6),

- }
- ACCESS read-only
- STATUS mandatory
- DESCRIPTION
- "This object contains the result of the most
- recently requested test, or the value
- none(1) if no tests have been requested since
- the last reset. Note that this facility
- provides no provision for saving the results
- of one test when starting another, as could
- be required if used by multiple managers
- concurrently."
- ::= { ifExtnsTestEntry 5 }
- ifExtnsTestCode OBJECT-TYPE
- SYNTAX OBJECT IDENTIFIER
- ACCESS read-only
- STATUS mandatory
- DESCRIPTION
- "This object contains a code which contains
- more specific information on the test result,
- for example an error-code after a failed
- test. Error codes and other values this
- object may take are specific to the type of
- interface and/or test. However, one subject
- identifier:
- testCodeUnknown OBJECT IDENTIFIER ::= { 0 0 }
- for use if no additional result code is
- available.
- Note that testCodeUnknown is a
- syntactically valid object identifier, and
- any conformant implementation of ASN.1 and
- the BER must be able to generate and
- recognize this value."

- ACCESS not-accessible
- STATUS mandatory
- DESCRIPTION
- "This table contains an entry for each
- address (broadcast, multicast, or uni-cast)

- interface is operating in promiscuous mode,
- entries are only required for those addresses
- for which the system would receive frames
- were it not operating in promiscuous mode."
- ::= { ifExtensions 3 }
- ifExtnsRcvAddrEntry OBJECT-TYPE
- SYNTAX IfExtnsRcvAddrEntry
- ACCESS not-accessible
- STATUS mandatory
- DESCRIPTION
- "A list of objects identifying an address
- for which the system will accept packets/

- ACCESS read-only

- DESCRIPTION
- "An address for which the system will accept

- ifExtnsRcvAddrStatus OBJECT-TYPE
- SYNTAX INTEGER {
- other(1),
- invalid(2),
- volatile(3),
- nonVolatile(4)
- }
- ACCESS read-write
- STATUS mandatory
- DESCRIPTION
- "This object has the value nonVolatile(4)
- for those entries in the table which are
- valid and will not be deleted by the next
- restart of the managed system. Entries
- having the value volatile(3) are valid
- and exist, but have not been saved, so
- that will not exist after the next
- restart of the managed system. Entries
- having the value other(1) are valid and
- exist but are not classified as to whether
- they will continue to exist after the next
- restart. Entries having the value invalid(2)
- are invalid and do not represent an address
- for which an interface accepts frames.
- Setting an object instance to one of
- the values other(1), volatile(3), or
- nonVolatile(4) causes the corresponding
- entry to exist or continue to exist, and
- to take on the respective status as regards
- the next restart of the managed system.
- Setting an object instance to the value
- invalid(2) causes the corresponding entry
- to become invalid or cease to exist.
- It is an implementation-specific matter
- as to whether the agent removes an
- invalidated entry from the table.
- Accordingly, management stations must be
- prepared to receive tabular information
- from agents that corresponds to entries not
- currently in use. Proper interpretation of
- such entries requires examination of the
- relevant ifExtnsRcvAddrStatus object
- instance."
