Chapter 9 Switch Operating Procedures
Managing Redundant APS Lines
Enter the dspapslns command to verify that the active line switched over from the protection line to the
working line, as shown in the following example:
mgx8830a.1.PXM.a > dspapslns

Displaying APS Line Information
To display the APS line redundancy configuration for a PXM card, enter the dspapsln command as
described in the following.
Step 1 Establish a configuration session at any access level.
Step 2 To view the redundancy status, enter the following command after the switch prompt:
mgx8830a.1.PXM.a > dspapsln <working-slot.bay.line>
Replace <working-slot.bay.line> with the slot, bay, and line id of the APS line you want to display. After
you enter the command, the switch displays a report similar to the following:

switchOption Method of performing the switchover. The possible methods are as follows:
• 1 = Clear previous user switchover requests. Return to working line only if the
mode is revertive.
• 2 = Lockout of protection. Prevents specified APS pair from being switched
over to the protection line. If the protection line is already active, the
switchover is made back to the working line.
• 3 = Forced working to protection line switchover. If the working line is active,
the switchover is made to the protection line unless the protection line is locked
out or in the SF condition, or if a forced switchover is already in effect.
• 4 = Forced protection to working line switchover. If the protection line is
active, the switch is made to the working line unless a request of equal or higher
priority is in effect. This option has the same priority as option 3 (forced
working to protection line switchover). Therefore, if a forced working to
protection line switchover is in effect, it must be cleared before this option
(forced protection to working line switchover) can succeed.
• 5 = Manual switchover from working to protection line unless a request of
equal or higher priority is in effect.
• 6 = Manual switchover from protection to working line. This option is only
available in the 1+1 APS architecture.
service switch This is an optional parameter. When set to 1, this field causes all APS lines to switch
to their protected lines.
