Card and Service Configuration
This chapter describes how to configure the MGX 8230 cards and the services they support.
This section also contains instructions to configure resource partitions, add local connections and
three-segment connections. Detailed descriptions of these tasks for individual service modules appear in
subsequent sections.
Although many of the configuration and connection tasks can be done with either Cisco WAN Manager
(CWM) and CiscoView network management applications, this appendix uses the MGX 8230 command
line interface commands in its examples. Refer to the appropriate CWM 9.2.xx and CiscoView 2.xx
documentation for information about using those applications with the MGX 8230.
Connections on a Feeder
The MGX 8230 MGX feeder can support local connections (daxcons) and three-segment connections
across the network. How you add connections depends on the technology of the service module, which
card is the master or slave end of the connection, and whether the connection is a daxcon or part of a
three-segment connection. The following rules govern connection addition in an MGX 8230 feeder.
The descriptions of connection addition later in this section reflect these rules:
1. If the MGX 8230 PXM is an endpoint, it functions as the slave. The service module is the master
end.
2. For a daxcon, you first add the connection at the slave end then add it at the master end. Further,
when you start by adding a connection at the slave end, the system generates the remote (master)
connection ID for you. The remote connection ID contains required information for adding the
connection at the master end.
3. For a three-segment connection, you start the segment by adding a connection at the master end. In
this case, you specify the connection ID of the slave end of the segment and subsequently use that
information for adding the connection at the slave end.
4. If the remote termination is an MGX 8230 PXM on the other side of a network cloud, specify the
slot number as “0.” (This requirement applies to only the feeder application of the MGX 8230.)
Modifying the Resource Partitioning
A resource partition on a card consists of a percentage of bandwidth, a DLCI or VPI/VCI range, and the
number of logical connection numbers (LCNs) available to a network control application. On the MGX
8230 PXM, the connections are global logical connections (GLCNs). By default, all resources on a
