Cisco BPX 8600 Series Installation and Configuration

Release 9.3.0, Part Number 78-10674-01 Rev. D0, July 2001

Chapter 24 Configuring BXM Virtual Circuits

BXM Commands

Note

You can configure the range of VPIs and VCIs reserved for PVC traffic and SVC traffic
by using the cnfport command. While adding connections, the system checks the entered
VPI/VPC against the range reserved for SVC traffic. If there is a conflict, the addcon
command fails with the message “VPI/VCI on selected port is reserved at local/remote
end”.

BXM Commands

This section provides a preliminary summary of configuration, provisioning, and monitoring
commands associated with the BXM cards. These commands apply to initial card configuration, line
and trunk configuration and provisioning, and connection configuration and provisioning.
