NTP- D109 Restore the Database
NTP-D109 Restore the Database
Caution
E1000-2 cards lose traffic for approximately 90 seconds when an ONS 15454 SDH database is restored.
Traffic is lost during the period of spanning tree reconvergence. The CARLOSS alarm appears and clears
during this period.
Caution
If you are restoring the database on multiple nodes, wait approximately one minute after the
TCC2/TCC2P reboot has completed on each node before proceeding to the next node.
Caution
TCC2P cards can be used in single IP address (repeater) and dual IP address (secured) mode. The
secured mode has advanced features that affect database restore: A database from a secured node cannot
be loaded on an unsecured repeater node. An unsecured database can be loaded onto a secured node but
the database will follow the node characteristics (that is, become secured). A secured database cannot
be loaded onto a TCC2; the restore is disallowed because the TCC2 card cannot boot in secure mode.
For more information about the dual IP secured mode, refer to the
.
Caution
To avoid a node IP and secure IP ending up in the same domain after restoring a database, ensure that
the node IP stored in the database differs in domain from that of the node in repeater mode. Also, after
restoring a database, ensure that the node IP and secure IP differ in domain.
Note
The following parameters are not backed up and restored: node name, IP address, subnet mask and
gateway, and IIOP port. If you change the node name and then restore a backed up database with a
different node name, the circuits map to the new renamed node. Cisco recommends keeping a record of
the old and new node names.
Note
ML-Series Ethernet cards must be reset after a database restore. For more information about restoring
these cards, refer to the
Ethernet Card Software Feature and Configuration Guide for the
Cisco ONS 15454, Cisco ONS 15454 SDH, and Cisco ONS 15327
.
Step 1
Complete the
“DLP-D60 Log into CTC” task on page 17-49
at the node where you are restoring the
database. If you are already logged in, continue with Step 2.
Purpose
This procedure restores the TCC2/TCC2P software database.
