Cisco ATM Services (AXSM) Configuration Guide and Command Reference for MGX Switches

Chapter 3 Provisioning ATM Services
General AXSM Configuration Procedures
In the configuration shown in Figure 3-5, the MGX 8850 switch supports up to 16 feeders. When using
the Cisco MGX 8850 PXM1-based switch as a feeder, you can route traffic to the core from the following
Cisco MGX 8850 PXM1-based service modules:
• AUSM
• CESM
• FRSM
• RPM
• VISM
The lower speed communication lines that connect to the feeder must exit the core network on lines that
lead to another feeder or CPE. To enable communications between a feeder and a remote feeder or CPE,
you need to configure an SPVC as described in the “Configuring SPVCs and SPVPs” section on
page 3-54. Table 3-11 identifies the supported interoperability between Cisco MGX 8850 PXM1-based
service modules over these AXSM SPVCs.
Note To operate properly, the Cisco MGX 8850 PXM1-based feeder must be running compatible software.
For information on the compatible feeder software, refer to the Release Notes for Cisco MGX 8850
(PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Switches, Release 5.2.00 or the Release
Notes for the Cisco MGX 8880 Media Gateway, Release 5.0.02.
The MGX 8850 switch uses the LMI Annex G protocol to communicate with the Cisco MGX 8850
PXM1-based feeder node. When you define a feeder port, you instruct the switch to use this protocol to
communicate with a feeder. The following procedure describes how to define a feeder port on the
MGX 8850 switch.
Step 1 Establish a configuration session using a user name at any user level.
Step 2 To identify a port as a feeder port, enter the addfdr command as follows:
M8950_DC.5.AXSM.a > addfdr <
ifNum
>
Replace ifNum with the interface number for the port. For example:
