h3cRTSubIfTable OBJECT-TYPE
SYNTAX SEQUENCE OF H3cRTSubIfEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"This table contains objects to create or delete subinterfaces.
To create a subinterface, a valid parent interface must be
specified by h3cRTSubIfParentIfIndex, and h3cRTSubIfOrdinal
must be in the range between h3cRTMinSubIfOrdinal and
h3cRTMaxSubIfOrdinal of the parent interface from
h3cRTParentIfTable.
Subinterfaces are logical virtual interfaces configured on a
main interface. The main interface can be either a physical
interface (such as a Layer 3 Ethernet interface) or a logical
interface (such as an MFR interface). The subinterfaces on a
main interface share the physical layer parameters of the main
interface but can have link layer and network layer parameters
of their own. Disabling or enabling a subinterface doesn't
affect the main interface, but the main interface status change
affects the subinterfaces. The subinterfaces can't operate
correctly unless the main interface is connected.
Creating multiple subinterfaces on a single interface
enables you to plan network in a more flexible way.
You can create subinterfaces for the following physical
interfaces:
Ethernet interface. An Ethernet subinterface associated with no
VLAN supports only IPX, while an Ethernet subinterface associated
with a VLAN supports both IP and IPX.
WAN interfaces with their data link layer protocols being frame
relay, whose subinterfaces support IP and IPX.
WAN interfaces with their data link layer protocols being X.25,
whose subinterfaces support IP and IPX.
ATM interface, whose subinterfaces support only IP."
