MIB Objects
ipRouteProto
1.3.6.1.2.1.4.21.1.9
read-only
INTEGER
The routing
mechanism by which
this route was
learned.
The constant value for this object is 2
(configured through local network
management).
ipRouteMask
1.3.6.1.2.1.4.21.1.11
read-only
IpAddress
The mask to be
logically ANDed with
the destination
address before being
compared to the
value of the
ipRouteDest object
If the value of the
ipRouteDest is
0.0.0.0 (a default
route), then the mask
value is also 0.0.0.0
(all IP routing
subsystems implicitly
use this mechanism).
The mask associated with a route is
retrieved by first obtaining the name of the
subnet from the ZSUBNET field in the
ZTCI-DDL-INFO-ROUTE structure. Using
the subnet object name, an INFO SPI
command is sent to the SUBNET object.
The mask value is contained in the
ZSUBNET-ZMASK field of the ZTCI-DDL-
INFO-SUBNET structure.
Because setting individual route masks is
not supported on the SPI interface, the
associated subnet mask is used to add
new routes.
ipRouteInfo
1.3.6.1.2.1.4.21.1.13
read-only
OBJECT
IDENTIFIER
A reference to MIB
definitions specific to
the particular routing
protocol responsible
for this route, as
determined by the
value specified for
the route’s
ipRouteProto object.
The constant value of this object is {0.0},
meaning that this information is not
present, as specified by RFC 1213.
ipNetToMediaTable
Objects:
Entries used for
mapping from IP
addresses to physical
addresses.
Refer to ipNetToMediaTable Maintenance
on page 8-51 for information on how
entries are maintained.
ipNetToMediaIfIndex
1.3.6.1.2.1.4.22.1.1
read-only
INTEGER
The interface for
which this entry
applies. The
interface identified by
a specific value of
this index is the
interface identified by
the same ifIndex
value.
The ipAddrTable.ipAdEntIfIndex is copied
into the
ipNetToMediaTable.ipNetToMediaIfIndex.
