General PXM1E Configuration Procedures
Table 3-2 lists the parameter descriptions for configuring SONET, DS3 and E3 lines. Be sure to use only
the parameters listed for E3 lines.
Step 5 To verify your configuration changes, enter the dspln command.
Verifying Line Configuration
To display the configuration of a line, use the following procedure.
Step 1 Establish a CLI management session at any user access level.
Step 2 If you do not know the line number you want to view, display a list of the lines by entering the following
command:
mgx8830b.2.PXM.a > dsplns
Step 3 To display the configuration of a single line, enter the following command:
mgx8830b.2.PXM.a > dspln -type <bay.line>
Table 3-3 describes the dspln command parameters. The line configuration appears as follows:
mgx8830b.2.PXM.a > dspln -sonet 2.1

Configuring Inverse Multiplexing for ATM
The Inverse Multiplexing for ATM (IMA) feature enables multiple T1 or E1 lines to be grouped into a
single high-speed ATM port. The advantage of the IMA feature is that you do not need T3/E3 circuits to
support high bandwidth on your switch. On Cisco MGX 8850 (PXM1E) and Cisco MGX 8830 switches,
Table 3-3 dspln Command Parameters
Parameter Description
type The parameter specifies the type of line that is connected to the switch. Replace
