Persistence
Optionally, the BOF persist parameter can specify whether the system should preserve system
indexes when a save command is executed. During a subsequent boot, the index file is read along
with the configuration file. As a result, a number of system indexes are preserved between reboots,
including the interface index, LSP IDs, path IDs, etc If persistence is not required and the
configuration file is successfully processed, then the system becomes operational. If persist is
required, then a matching
x.ndx file must be located and successfully processed before the system
can become operational. Matching files (configuration and index files) must have the same
filename prefix such as
test123.cfg and test123.ndx and are created at the same time when
a save command is executed. Note that the persistence option must be enabled to deploy the
Network Management System (NMS). The default is off.
Traps, logs, and console messages are generated if problems occur and SNMP shuts down for all
SNMP gets and sets, however, traps are issued.
