The configuration for logging on a 1841 router is as following:

router#sh log

Syslog logging: enabled (1 messages dropped, 2 messages rate-limited,

0 flushes, 0 overruns, xml disabled, filtering disabled)

Console logging: level debugging, 168 messages logged, xml disabled,

filtering disabled

Monitor logging: level debugging, 0 messages logged, xml disabled,

filtering disabled

Buffer logging: level debugging, 168 messages logged, xml disabled,

filtering disabled

Logging Exception size (4096 bytes)

Count and timestamp logging messages: disabled

On the serial interface counters for abort and carrrier transition are >1000 and >270, last clearing of counters was 1d6h ago.

Since the last clearing of counters there is absolutely no entry in the log.

Why? Were the carrier transitions / aborts to short for beeing recorded in the log or do we have to enable a "higher level" logging?

Thank you for the answer,

Martin Funke.
