ATM Virtual Channel Link Parameters
ATM virtual channel link parameters define PVCs in a PVC service record.
Note:
ATM does not allow duplicate VPI/VCI pairs on the same physical
interface. However, duplicate VPI/VCI pairs can exist on different physical
interfaces.

Default: None
Options: 0 to 255
Function: Identifies the virtual path of the PVC. The VPI is part of the cell header. The
header can contain a maximum of 8 VPI bits for a UNI connection. This bit
range allows for path identifiers from 0 to 255.
Instructions: Enter a value from 0 to 255.
MIB Object ID: 1.3.6.1.4.1.18.3.4.23.1.5.1.3

Default: None
Options: 32 to 65535
Function: Identifies the virtual channel of the PVC. The VCI is part of the cell header. The
header can contain a maximum of 16 VCI bits. This bit range allows for path
identifiers from 0 to 65535.
Instructions: Enter a value from 32 to 65535.
MIB Object ID: 1.3.6.1.4.1.18.3.4.23.1.5.1.4
Note:
Following the recommendation of the ATM Forum, virtual channel
identifiers from 0 to 31 are reserved for signaling and added functionality.
