*When configuring a SVC connection, ensure the correct PTOP indexes are mapped to the switch you are connecting to. **When configuring a PVC connection, ensure the VCI values are identical on the switches you are connecting to.

***When configuring PVC connections through an ATM switch, ensure the bi-directional path is established per port/interface on the ATM switch.

****Valid PTOP index ranges from 0 through 15.

*****When configuring PVC, valid VCI values begin with 32.

Trunking

Trunking allows multiple VLANs to share the same virtual channel connection (VCC) using either Permanent Virtual Connections (PVCs) or Switched Virtual Connections (SVCs). Unlike PTOP, VLAN information is passed across ATM thereby simplifying configuration.
