Chapter 25 Configuring SONET Automatic Protection System
Test Loops
Test Loops
The test commands
addlnloclp
and
addlnrmtlp
may affect service even when APS is configured. In all
APS configurations, if the working line is looped, both lines are looped and traffic disrupted.
Notes on APS Messages
When adding an APS 1+1 line or trunk by using
addapsln
, if the working slot’s paired redundant slot is
not a legal protection slot, or if firmware cannot determine what the paired slot is, an invalid slot pairing
exists and one of the following two messages are displayed:
Protection card specified by user does not match HW.
Working card specified by user does not match HW.
You can display the redundant card information by using the
dspcd
command under the “Backcard
Installed” heading. For example, if a redundant pair is configured with a primary slot of 2 and a
secondary slot of 3, the
dspcd
2 command displays
RedSlot: 3
, and the
dspcd
3 command displays
RedSlot: 2
.
The following is an example of
dspcd
