Setting Up Ports and Virtual Ports

Once you have set up a circuit line, you are ready for the next step in adding connections. You can also
create a port or one or more virtual ports for the line.
A port is the unique logical interface between the BPX network and a single attached ATM device shown
in Figure 19-2.

ASI or BXM
Once you have activated a line by using the upln command, set up a port or virtual port by using the
following procedure.
Step 1 Add a port by using the addport X.Y[.Z] command. For example, X is the slot, Y is the port, and Z is
an optional virtual port number.
Activate the port by using the upport X.Y[.Z] command. For example, X is the slot, Y is the port, and
Step 2
Z is an optional virtual port number.
Enter the cnfport command to establish the characteristics for the port.

Physical Interface
When adding a connection to a virtual port on a BXM card, the virtual port number is not
required. The slot, port, and VPI will map to the supporting virtual port.
If a slot-port combination for a BXM card has been brought up as a port (upport X.X), the
slot-port cannot have virtual ports activated unless the port is first deleted (delport X.X). The
opposite also applies; once a virtual port is configured, it cannot be used as a port until all
virtual ports are deleted (delport X.X).
