IP
IP: General Tab
| Total datagrams received | The total number of input datagrams received from interfaces, including those received in error. |
| Forwarding capability | This indicates whether this entity is acting as an IP gateway in respect to the forwarding of datagrams received by, but not addressed to, this entity. IP gateways forward datagrams. IP hosts do not (except those source-routed via the host). Note that for some nodes, this object may take on only a subset of the values possible. Accordingly, it is appropriate for an agent to return a badValue response if a management station attempts to change this object to an inappropriate value. |
| Default time-to-live | The default value inserted into the Time-To-Live (TTL) field of the IP header of datagrams originated at this entity, whenever a TTL value is not supplied by the transport layer protocol. |
| Reassembly timeout(s) | The maximum number of seconds which received fragments are held while they are awaiting reassembly at this entity. |
| Reassemblies required | The number of IP fragments received which needed to be reassembled at this entity. |
| Reassembled datagrams | The number of IP datagrams successfully re-assembled. |
| Fragmented datagrams | The number of IP datagrams that have been successfully fragmented at this entity. |
| Fragmentation failures | The number of IP datagrams that have been discarded because they needed to be fragmented at this entity but could not be (for example, because their Don't Fragment flag was set). |
| Created due to fragmentation | The number of IP datagram fragments that have been generated as a result of fragmentation at this entity. |
| Routing discards | The number of routing entries that were discarded although they were valid. A reason for discard could be to free up buffer space for other routing entries. |
Inbound Details
| Delivered | The total number of input datagrams successfully delivered to IP user-protocols including Internet Control Message Protocol (ICMP). |
| Header errors | The number of input datagrams discarded due to errors in their IP headers, including bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options, and so on. |
| Address errors | The number of input datagrams discarded because the IP address in their IP header's destination field was not a valid address to be received at this entity. This count includes invalid addresses (for example., 0.0.0.0) and addresses of unsupported Classes (for example., Class E). For entities which are not IP Gateways and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address. |
| Unknown protocols | The number of locally-addressed datagrams received successfully but discarded because of an unknown or unsupported protocol. |
| Discards | The
number of input IP datagrams for which no problems were encountered to prevent
their continued processing, but which were discarded (for example, for lack of
buffer space).
Note: This counter does not include any datagrams discarded while awaiting re-assembly. |
Outbound Details
| Requests | The
total number of IP datagrams which local IP user-protocols (including ICMP)
supplied to IP in requests for transmission.
Note: This counter does not include any datagrams counted in ipForwDatagrams. |
| Discards | The
number of output IP datagrams for which no problem was encountered to prevent
their transmission to their destination, but which were discarded (e.g., for
lack of buffer space).
Note: This counter would include datagrams counted in ipForwDatagrams if any such packets met this (discretionary) discard criterion. |
| No routes | Number of IP datagrams discarded because a
route could not be found to transmit them to their destination.
Note: This counter includes any packets counted in ipForwDatagrams which meet this no-route criterion. This includes any datagrams which a host cannot route because all of its default gateways are down. |
Addresses Tab
| IP Address | The IP address to which this entry's addressing information pertains. |
| Interface Index | The index value which uniquely identifies the interface to which this entry is applicable. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex. |
| Network mask | Subnet mask associated with the IP address of this entry. The value of the mask is an IP address with all the network bits set to 1 and all the host bits set to 0. |
| Broadcast address | The value of the least-significant bit in the IP broadcast address used for sending datagrams on the (logical) interface associated with the IP address of this entry. For example, when the Internet standard all-ones broadcast address is used, the value is 1. This value applies to both the subnet and network broadcasts addresses used by the entity on this (logical) interface. |
| Max reassembly size | The size of the largest IP datagram which this entity can re-assemble from incoming IP fragmented datagrams received on this interface. |
Interface Stats Tab
| 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. |

| 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. |
