APS Switchover During CFM/CPM Switchover
An APS switchover immediately before, during or immediately after a CFM/CPM switchover
may cause a longer outage than normal.
Removing or Failure of a Protect MDA
The detection of a CMA/MDA removal or a CMA/MDA failure can take additional time. This can
affect the APS switchover time upon the removal or failure of a protection CMA/MDA. If the
removal is scheduled during maintenance, it is recommended that the port and/or protect circuit be
shutdown first to initiate an APS switchover before the CMA/MDA maintenance is performed.
Mirroring Support
Mirroring parameters configured on a specific port or service, are maintained during an APS
failover.
