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. Det aile d descr ip tions of the se tas ks for individual service modules appe ar i n
subsequent sections.
Although many of the configur ation and connection tasks can be done with either Cisco WAN Manager
(CWM) and CiscoView netwo rk man agem ent appl ic ati ons, thi s app en dix us es th e MGX 8 230 comma nd
line interface commands in its examp l es. Refer to the appropriate CW M 9 .2 .x x an d C isc oView 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 sl ave end of the connecti on , and whether the co n ne c ti o n is a daxcon or part o f a
three-segment connection. The following rules govern connection addition in an MGX 8230 feeder.
The descriptions of connec tion addition later in thi s s ec tio n r ef lec t 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 seg men t by ad ding a con ne cti o n at the master end. In
this case, you specify the con n ect io n ID o f th e s lave end o f th e s eg men t and subsequently use that
information for adding the c on n ect io n at th e s l ave en d.
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 applie s t o on ly t he f eed er a pp li cat io n of t he M G X 8 23 0. )

Modifying the Resource Partitioning

A resource partition on a card consists of a percentage of band wid th, a DLCI or VPI /VCI ran ge, and the
number of logical connectio n numbers (LCNs) available to a ne twork control application. On t he MGX
8230 PXM, the connections are g l ob al lo g ica l connections (GLCNs). By defau lt , a ll resources on a
