The -1 entries in the example above indicate that a value was not specified with the addcon command.
The N/A entries indicate that a value is not applicable to connections with this service type.
Step 6 To display connections from the PXM card, enter the cc command to select the active PXM, then enter
the dspcons command, as follows:
MGX8850.7.PXM.a > dspcons
The following example shows the report for the connection shown in the preceding examples.

Defining a Feeder Port
An ATM feeder node provides a connection between multiple relatively slow lines (such as T1 lines) and
a relatively faster uplink (such as an OC-3 line) to an ATM core network. Feeders such as the Cisco MGX
8850 PXM1-based switch can concatenate traffic from Frame Relay, ATM, circuit emulation, and voice
circuits for transmission over the core to other feeders or to Customer Premise Equipment (CPE).
Note Feeder ports are not supported on MGX 8950 switches and AXSM-E cards.
Figure 3-5 shows a topology that includes a Cisco MGX 8850 PXM1-based feeder node.
