Module rasn_mib::interfaces

The Interfaces Group

Implementation of the Interfaces group is mandatory for all systems.

Structs

• AdminStatus
  The desired state of the interface. The Self::TESTING state indicates that no operational packets can be passed.
• Descr
  A textual string containing information about the interface. This string should include the name of the manufacturer, the product name and the version of the hardware interface.
• Entry
  An interface entry containing objects at the subnetwork layer and below for a particular interface.
• InDiscards
  The number of inbound packets which were chosen to be discarded even though no errors had been detected to prevent their being deliverable to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer space.
• InErrors
  The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.
• InNUcastPkts
  The number of non-unicast (i.e., subnetwork-broadcast or subnetwork-multicast) packets delivered to a higher-layer protocol.
• InOctets
  The total number of octets received on the interface, including framing characters.
• InUcastPkts
  The number of subnetwork-unicast packets delivered to a higher-layer protocol.
• InUnknownProtos
  The number of packets received via the interface which were discarded because of an unknown or unsupported protocol.
• Index
  A unique value for each interface. Its value ranges between 1 and the value of Number. The value for each interface must remain constant at least from one re-initialization of the entity’s network management system to the next re-initialization.
• LastChange
  The value of system::UpTime at the time the interface entered its current operational state. If the current state was entered prior to the last re-initialization of the local network management subsystem, then this object contains a zero value.
• Mtu
  The size of the largest datagram which can be sent/received on the interface, specified in octets. For interfaces that are used for transmitting network datagrams, this is the size of the largest network datagram that can be sent on the interface.
• Number
  The number of network interfaces (regardless of their current state) present on this system.
• OperStatus
  The current operational state of the interface. The Self::TESTING state indicates that no operational packets can be passed.
• OutDiscards
  The number of outbound packets which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space.
• OutErrors
  The number of outbound packets that could not be transmitted because of errors.
• OutNUcastPkts
  The total number of packets that higher-level protocols requested be transmitted to a non-unicast (i.e., a subnetwork-broadcast or subnetwork-multicast) address, including those that were discarded or not sent.
• OutOctets
  The total number of octets transmitted out of the interface, including framing characters.
• OutQLen
  The length of the output packet queue (in packets).
• OutUcastPkts
  The total number of packets that higher-level protocols requested be transmitted to a subnetwork-unicast address, including those that were discarded or not sent.
• PhysAddress
  The interface’s address at the protocol layer immediately “below” the network layer in the protocol stack. For interfaces which do not have such an address (e.g., a serial line), this object should contain an octet string of zero length.
• Specific
  A reference to MIB definitions specific to the particular media being used to realize the interface. For example, if the interface is realized by an ethernet, then the value of this object refers to a document defining objects specific to ethernet. If this information is not present, its value should be set to the OBJECT IDENTIFIER { 0 0 }, which is a syntactically valid object identifier, and any conformant implementation of ASN.1 and BER must be able to generate and recognize this value.
• Speed
  An estimate of the interface’s current bandwidth in bits per second. For interfaces which do not vary in bandwidth or for those where no accurate estimation can be made, this object should contain the nominal bandwidth.
• Table
  A list of interface entries. The number of entries is given by the value of Number.
• Type
  The type of interface, distinguished according to the physical/link protocol(s) immediately “below” the network layer in the protocol stack.
