Configuring ATM PVCs
Setting the VPI/VCI Values for PVCs
VCI (1..nnnn) — (for VCCs only) Depending on the circuit configuration, enter a
value to represent the VCI for an ATM PVC. Although you can configure VCIs in the
1 – 31 range (with the exception of VCI = 3 and 4), the ATM Forum reserves VCIs in
this range for various purposes. You should only use a VCI in the 1–31 range if you
are certain that compatibility issues will not arise with any attached non-Lucent
equipment. If you are configuring a circuit with ATM CE endpoints, the VCI value
defaults to 256. See
Note – Navis EMS-CBGX fills the VCI and VPI fields with the next available VCI or
VPI value. You can use these values or override either one by entering your own value
in either the VCI or VPI fields.
