General AXSM Configuration Procedures
Step 8 To display a list showing the resource partition you created, enter the dspparts command:
M8950_DC.5.AXSM.a > dspparts
if part Ctlr egr egr ingr ingr min max min max min max

11 2 5 500000 500000 500000 500000 0 10 32 65535 1000 4000
Step 9 To display the configuration of a specific resource partition, enter the dsppart <ifNum> <partId>
command. Replace <ifNum> with the number of interface (or port) whose resource partition you want to
display, and replace <partId> with the partition ID number. (See Table 3-3 for a description of the
<ifNum> and <partId> parameters.)
dsppart < ifNum > < partId >
The following example shows the report provided by the dsppart command.
M8950_DC.5.AXSM.a > dsppart 11 2
Interface Number : 11

egr Guaranteed bw(.0001percent): 500000 Number of SVC : 0
egr Maximum bw(.0001percent) : 500000
ing Guaranteed bw(.0001percent): 500000

min vpi : 0
max vpi : 10
min vci : 32

Tip To change the port configuration, enter the cnfport command, or enter the delport command to delete
a port configuration. You can also activate and deactivate ports using the upport and dnport commands.
Configuring Inverse Multiplexing over ATM
Inverse Multiplexing over ATM (IMA) is a protocol that runs on the AXSM-32-T1E1-E. IMA allows
you to combine multiple T1 or E1 interfaces into a single, high-speed IMA interface. These
combinations of multiple links are called IMA groups. IMA groups are comprised of IMA links.
The AXSM-32-T1E1-E supports a maximum of 32 IMA groups; 16 groups in the top bay and 16 groups
in the bottom bay. All the IMA links in an IMA group must be in the same bay.
IMA is also supported on the following Cisco MGX cards:
• PXM1E-16-T1E1 (supports a maximum of 16 IMA groups in the bottom bay only)
• AUSM-8-T1/B (supports a maximum of 8 IMA groups)
• AUSM-8-E1/B (supports a maximum of 8 IMA groups)
SCTs number 54 and 55 provide support for IMA groups. However they only support IMA groups with
up to 4 lines. You must create your own SCTs for IMA groups with more than 4 lines.
The Cisco MGX 8850 (PXM45) and Cisco MGX 8950 support IMA Versions 1.0 and 1.1.
