| Index
|
The unique value for each interface. Value has a range between 1 and the value of ifNumber and must remain constant at least from one re-initialization of the entity's NMS to the next re-initialization.
|
| Name
|
The interface name.
|
| Description
|
The text string containing information about the interface. This string includes the name of the manufacturer, the product name, and the version of the hardware interface.
|
| Type
|
The information about the type of interface, distinguished according to the physical/link protocol(s) immediately below the network layer in the protocol stack.
|
| MTU
|
The size of the largest datagram which can be sent/received on the interface, specified in octets. For interfaces that transmit network datagrams, this is the size of the largest network datagram that can be sent on the interface
|
| Speed
|
The estimate of the current bandwidth of the interface in bits per second. For interfaces which do not vary in bandwidth or for those where an accurate estimation cannot be made, it contains the nominal bandwidth.
|
| Physical address
|
The address of the interface at the protocol layer immediately below the network layer in the protocol stack. For interfaces which do not have such an address (for example, a serial line), it contains an octet string of zero length.
|
| Admin status
|
Current administrative state of the interface. The values are:
|
| Operational status
|
Current operational state of the interface. The values are:
|
| Last change time
|
The value of sysUpTime 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 it contains a zero value.
|
| In octets
|
The total number of octets received on the interface, including framing characters.
|
| Unicast packets in
|
The number of subnetwork-unicast packets delivered to a higher-layer protocol.
|
| Non-unicast packets in
|
The number of non-unicast (for example, subnetwork-broadcast or subnetwork-multicast) packets delivered to a higher-layer protocol.
|
| In discards
|
The number of inbound packets which were chosen to be discarded although no errors had been detected to prevent their being delivered to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer space.
|
| In errors
|
The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.
|
| In unknown protocols
|
For packet-oriented interfaces, the number of packets received through the interface which were discarded because of an unknown or unsupported protocol. For character-oriented or fixed-length interfaces that support protocol multiplexing, the number of transmission units received via the interface which were discarded because of an unknown or unsupported protocol. For any interface that does not support protocol multiplexing, this counter is always zero.
|
| Out octets
|
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.
|
| Unicast packets out
|
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.
|
| Non-unicast packets out
|
The total number of packets that higher-level protocols requested be transmitted to a non-unicast (that is, a subnetwork-broadcast or subnetwork-multicast) address, including those that were discarded or not sent.
|
| Out discards
|
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.
|
| Out errors
|
The number of outbound packets that could not be transmitted because of errors.
