PVC ID settings
VPI The virtual path identifier of the PVC. In conjunction with the VCI,
identifies the next destination of a cell as it passes through a series of ATM
switches on the way to its destination. Valid values for most platforms range
from 0 to 255.
For Cisco 2600 and 3600 Series routers using Inverse Multiplexing for ATM
(IMA), valid values range from 0 to 15, 64 to 79, 128 to 143, and 192 to 207.
Note VPI/VCI values must be unique for all the PVCs configured on a
selected interface. VPI/VCI values are unique to a single link only
and might change as cells traverse the ATM network.
VCI The 16-bit virtual channel identifier of the PVC. In conjunction with the
VPI, identifies the next destination of a cell as it passes through a series of
ATM switches on the way to its destination. Valid values vary by platform.
Typically, values up to 31 are reserved for special traffic (such as ILMI) and
should not be used. 3 and 4 are invalid.
Note VPI/VCI values must be unique for all the PVCs configured on a
selected interface. VPI/VCI values are unique to a single link only
and might change as cells traverse the ATM network.
Handle An optional name to identify the PVC. The maximum length is 15
characters.
Management PVC
(ILMI)
Does not apply when configuring the PVC on a subinterface.
When selected, designates this PVC as the management PVC for this ATM
interface by enabling communication with the Interim Local Management
Interface (ILMI). ILMI is a protocol defined by the ATM Forum for setting
and capturing physical layer, ATM layer, virtual path, and virtual circuit
parameters on ATM interfaces. See Understanding ILMI, page 15-50.
When deselected, this PVC does not act as the management PVC. This is the
default.
Note The VPI/VCI for the management PVC is typically set to 0/16.
