General PXM1E Configuration Procedures
Step 4 To display a list of all APS lines on a PXM1E, enter the dspapslns command on the active PXM1E card.
Step 5 To display information on a specific APS line, enter the dspapsln <slot.bay.line> command on the active
PXM1E card.
For information on managing APS lines, see the
"Switch Operating Procedures."

Configuring Intercard APS Lines

Intercard APS configurations are created with the working and protection lines on different back cards.
As shown in
redundant front cards to back cards and lines.
Figure 3-3
Back card and line fault tolerance is provided by intercard APS. If the working line or the back card to
which it is connected fails, communications traffic is rerouted through the protection line and the back
card to which it is connected.
When planning a redundant line configuration that uses intercard APS on PXM1E, consider the
following requirements:

APS is not supported on T1, E1, T3, and E3 interfaces.
Redundant PXM1E cards must be installed in the switch.
Some PXM1E back card types require an APS mini-backplane to support intercard APS. The
PXM1E APS mini-backplane requirements are describe in the Cisco MGX 8850 (PXM1E/PXM45),
Cisco MGX 8950, Cisco MGX 8830, and Cisco MGX 8880 Hardware Installation Guide, Releases
2 Through 5.
