Configuring Connections
Connections are typically provisioned and configured using Cisco StrataView Plus. However, the
connections can also be added using the BPX switch command line interface (CLI). This may be
appropriate during initial local node setup and when a Strata View Plus workstation is not available.
There are two connection addressing modes supported. The user may enter a unique VPI/VCI
address in which case the BPX switch functions as a virtual circuit switch. Or the user may enter
only a VPI address in which case all circuits are switched to the same destination port and the BPX
switch functions as a virtual path switch in this case. The full ATM address range for VPI and VCI
is supported.
Connections are routed between CPE connected to BXM ports. Before adding connections, the
BXM is configured for port mode.
Note The initial command to up a trunk (uptrk) or to up a line (upln) on the BXM card configures
all the ports of the card to be either trunks or lines (UNI port access). Following the uptrk command
at each port, the addtrk command is used to activate a trunk for network access.
A line is upped with the upln command and configured with the cnfln command. Then the
associated port is configured with the cnfport command and upped with the upport command.
Following this, the ATM connections are added via the addcon command.
The slot number is the BXM card slot on the BPX switch. The port number is one of the ports on the
BXM, the VPI is the virtual path identifier, and the VCI is the virtual circuit identifier.
The VPI and VCI fields have significance only to the local BPX switch, and are translated by tables
in the BPX switch to route the connection. Connections are automatically routed by the AutoRoute
feature once the connection endpoints are specified.
Connections can be either Virtual Path Connections (VPC) or Virtual Circuit Connections (VCC).
Virtual Path Connections are identified by an * in the VCI field. Virtual Circuit Connections specify
both the VPI and VCI fields.
Configuration Management
The following parameters are entered for the BXM addcon command. Depending upon the
connection type, the user is prompted with appropriate parameters as shown below.
Syntax:
addcon local_addr node remote_addr traffic_type ...extended parameters
