addcon Command Syntax
Enter the following parameters for the BXM addcon command. Depending upon the connection type,
you are prompted for the appropriate parameters as shown in the following example:
addcon local_addr node remote_addr traffic_type/class number....extended parameters
EXAMPLES
addcon 2.2.11.11 pubsbpx1 2.3.12.12 3
addcon 2.3.22.22 pubsbpx1 2.2.24.24 abrstd 50/50 100/100 50/50 25000/* e e e d 50/50 * 3 *
80/* 35/* 20/* 50/* * 100 128 16 32 0 *
The field descriptions are described in Table 21-4.
Note
The range of VPIs and VCIs reserved for PVC traffic and SVC traffic is configurable 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”.
addcon Example
The following example shows the initial steps in adding a connection with the addcon command, and
the addcon prompt requesting the user to enter the ATM type of service.

Table 21-4 addcon Command Field Descriptions
Field Value Description
local/remote_addr slot.port.vpi.vci Specifies the desired VCC or VPI connection identifier.
node Determines the slave end connection.
traffic_type/connection
class Determines the type of traffic that is chosen from the service type
(nrt/rt-VBR, CBR, UBR, ABRSTD, ABRFST, ATFR, ATFST, ATFT,
ATFTFST, ATFX, ATFXFST) or connection class. For example, for
rt-VBR, connection class 3 for a new node running Release 9.2.20.
Note For a new node running 9.2.20 or later, the rt-VBR connection
class number is 3. An upgraded node retains existing connection
classes. Therefore, it won’t have the rt-VBR connection class 3.
However, you can configure the connection classes to whatever
service and parameters you want using the cnfcls/cnfatmcls
command.
extended parameters Specifies additional traffic management and performance parameters
associated with some of the ATM connection types. For example,
ABRSTD with VS/VD enabled and default extended parameters disabled.
