Table 2-2: ATM Virtual Interface Configuration Group MIB Objects
Name Syntax Description Default Value

caviTable

Sequence of caviEntry

The ATM virtual interfaces are created on physical interfaces. For each entry created in this table, there will be an entry created in the ifTable with ifType atmVirtual(149). For each entry deleted from this table, the corresponding entry from ifTable will be deleted. The ifIndex value for ifType atmVirtual(149) is used for indexing to atmInterfaceConfTable for getting information on an ATM virtual interface.

Max-Access: not-accessible

Status: current

Dependencies/Restrictions: The parameters cannot be changed if there are one or more resource partitions configured on the interface.

none

caviEntry

caviEntry

Provides an entry in the caviTable table for each ATM virtual interface. This entry is created only if values for all objects in a row are provided. The caviVpiNum value is required only if caviIfType is vuni(4) or vnni(5).

Max-Access: not-accessible

Status: current

Created By: Manager

The index contains caviIndex.

The following is the referential integrity constraints:

none

caviIndex

Integer32 (1..2147483647)

Provides a unique value for the ATM virtual interface.

Max-Access: not accessible

The following fields are used the index entry format:

none

Field Description Bit Positions

24-31 (eight bits)

Logical Slot #

Logical Slot Number of the module that is plugged in.

16-23 (eight bits)

Value

(See Table 2-1.)

0-15 (Refers to a number between 1 and 60)

caviPhyIfIndex

InterfaceIndex

Identifies the interface number ifIndex assigned to SONET(39), ds3(30), ds1(18), atmIma(107).

Max-Access: read-create

Status: current

none

caviViIfIndex

InterfaceIndex

Identifies the ATM virtual interface number ifIndex assigned to this entry, which is used to identify corresponding rows in the IF-MIB.


Note   Reinitialization of the management agent can cause a client's caviViIfIndex to change.

For information on the Chassis/Slot (or CS) format used for this index entry, see caviIndex.

Max-Access: read-only

Status: current

none

caviMinRate

Unsigned32

Describes the ATM virtual interface's Minimum Cell Rate (MCR). This is the guaranteed bandwidth allocated for the interface. The sum of caviMinRate of all ATM virtual interfaces configured on a single physical line, must not exceed the bandwidth of the physical line. Creation of a row is rejected when the sum of caviMinRate of all existing ATM virtual interfaces exceeds the physical line bandwidth. The value of this object cannot exceed the ifSpeed or ifHighSpeed value in ifTable for the associated caviPhyIfIndex.

Units: cells-per-second

Max-access: read-create

T3

96000

E3

80000

caviMaxRate

Unsigned32

Describes the ATM virtual interface's maximum cell rate. If bandwidth is available, the interface will be allocated bandwidth up to this value. This is the maximum bandwidth allocated for the interface. The total bandwidth of connections configured over this interface cannot exceed this value. The value of this object cannot exceed the ifSpeed or ifHighSpeed value in ifTable for the associated caviPhyIfIndex.

For information about the ATM cell bandwidths for various physical lines, see caviMinRate.
