The simplest form of LSN and L2-Aware NAT logging is via logging facility in the 7750 SR, commonly called logger. Each port-block allocation/de-allocation event is recorded and send to the system logging facility (logger). Such an event can be:
recorded in the system memory as part of regular logs
written to a local file
sent to an external server by a syslog facility
sent to a SNMT trap destination
In this mode of logging, all applications in the system share the same logger.
Syslog/SNMP/Local-File logging on LSN and NAT RADIUS-based logging are mutually exclusive.
Syslog/SNMP/local-file logging must be separately enabled for LSN and L2-Aware NAT in log even-control. The following displays relevant MIB events:
