1.3.6.1.4.1.43.45.1.10.2.40.2.2.2
This table contains objects to create or delete sub interfaces.
To create a sub interface, a valid parent interface must be
specified by h3cRTSubIfParentIfIndex and the h3cRTSubIfOrdinal
must be in the range between h3cRTMinSubIfOrdinal and
h3cRTMaxSubIfOrdinal of the parent interface from
h3cRTParentIfTable.
Sub interfaces 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 does not
affect the main interface, but the main interface status change
affects the subinterfaces. The subinterfaces cannot operate
normally unless the main interface is connected.
A single physical interface containing multiple subinterfaces
enables you to 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.
