ipForwarding (1) RW
Indicates if the device operates as a gateway. IP
gateways can transfer datagrams, but IP hosts
can perform only source routing. Some nodes
take only one of these values. Therefore, if you
attempt to change this object from the SNMP
Manager, a badValue error is returned.

IpInReceives (3) RO
The number of all IP datagrams that reached the

operate as an IP gateway, this is the number of
datagrams that were successfully transferred
through source routing.
Sup-
ported.
According to the
standard.
ipInUnknownProtos (7) RO
The number of IP datagrams that were received
but discarded because they were of an unsup-
ported or unrecognized protocol.
Sup-
ported.
According to the
standard.
ipInDiscards (8) RO
