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.
Lawful Intercept
Lawful Intercept (LI) describes a process to intercept telecommunications by which law
enforcement authorities can un-obtrusively monitor voice and data communications to combat
crime and terrorism with higher security standards of lawful intercept capabilities in accordance
with local law and after following due process and receiving proper authorization from competent
authorities. The interception capabilities are sought by various telecommunications providers.
As lawful interception is subject to national regulation, requirements vary from one country to
another. Alcatel-Lucent’s implementation satisfies most national standard’s requirements. LI is
configurable for all service types.
