ipRouteMask
1.3.6.1.2.1.4.21.1.11
Read-write The mask to be logical-ANDed with the destination address before being
compared to the value in the ipRouteDest field. For those systems that do
not support arbitrary subnet masks, an agent constructs the value of the
ipRouteMask by determining whether the value of the correspondent
ipRouteDest field belong to a class-A, B, or C network, and then using one
of the following:
mask network
255.0.0.0 class-A
255.255.0.0 class-B
255.255.255.0 class-C
NOTE: If the value of the ipRouteDest is 0.0.0.0 (default route), then the
mask value is also 0.0.0.0.
All IP routing subsystems implicitly use this mechanism.
ipRouteMetric5
1.3.6.1.2.1.4.21.1.12
Read-write An alternate routing metric for this route.
The semantics of this metric are determined by the routing protocol
specified in the route's ipRouteProto value. If this metric is not used, its
value should be set to -1.
ipRouteInfo
1.3.6.1.2.1.4.21.1.13
Read only A reference to MIB definitions specific to the particular routing protocol that
is responsible for this route, as determined by the value specified in the
route's ipRouteProto value. If this information is not present, its value
should be set to the Object Identifier {0 0}, which is a syntactically valid
object identifier; any conferment implementation of ASN.1 and BER must
be able to generate and recognize this value.
ipNetToMediaTable
1.3.6.1.2.1.4.22
Not
accessible
The IP Address Translation table used for mapping from IP addresses to
physical addresses.
NOTE: The IP address translation table contains the IP address to physical
address equivalences. Some interfaces do not use translation
tables for determining address equivalences. For example,
DDN-X.25 has an algorithmic method; if all interfaces are of this
type, then the Address Translation table is empty.
ipNetToMediaEntry
1.3.6.1.2.1.4.22.1
Not
accessible
Each entry contains one IP address to physical address equivalence.
ipNetToMediaIfIndex
1.3.6.1.2.1.4.22.1.1
Read-write The interface on which this entry's equivalence is effective.
The interface identified by a particular value of this index is the same
interface identified by the same value of ifIndex.
iipNetToMediaPhysAd
dress
1.3.6.1.2.1.4.22.1.2
Read-write The media-dependent physical address.
ipNetToMediaNetAddr
ess
1.3.6.1.2.1.4.22.1.3
Read-write The IpAddress corresponding to the media-dependent physical address.
ipNetToMediaType
1.3.6.1.2.1.4.22.1.4
Read-write The type of mapping.
ipRoutingDiscards
1.3.6.1.2.1.4.23
Read only The number of routing entries discarded even though they are valid. One
possible reason for discarding such an entry could be to free buffer space
for other routing entries.
NOTE: This object is not supported.
