MIB-2 Object
Name
Type Access Description
ipForwarding INTEGER R/W The indication of 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 managed 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.
ipDefaultTTL INTEGER R/W The default value inserted into the Time-To-Live field of the IP header of datagrams
originated at this entity, whenever a TTL value is not supplied by the transport layer
protocol.
ipInReceives Counter R The total number of input datagrams received from interfaces, including those
received in error.
ipInHdrErrors Counter R 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, etc.
ipInAddrErrors Counter R 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 (e.g., 0.0.0.0) and addresses of unsupported
Classes (e.g., 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.
ipForwDatagrams Counter R The number of input datagrams for which this entity was not their final IP
destination, as a result of which an attempt was made to find a route to forward
them to that final destination. In entities which do not act as IP Gateways, this
counter will include only those packets which were Source-Routed via this entity,
and the Source- Route option processing was successful.
ipInUnknownProtos Counter R The number of locally-addressed datagrams received successfully but discarded
because of an unknown or unsupported protocol.
ipInDiscards Counter R 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 that this counter does not include any datagrams
discarded while awaiting re-assembly.
ipInDelivers Counter R The total number of input datagrams successfully delivered to IP user-protocols
(including ICMP)
