Hi


Here's my output from "sh log" (note the syslog part):


Syslog logging: enabled (96 messages dropped, 259 messages rate-limited, 0 flushes, 0 overruns, xml disabled, filtering disabled)

Console logging: disabled

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

filtering disabled

Buffer logging: level debugging, 464 messages logged, xml disabled,

filtering disabled

Exception Logging: size (4096 bytes)

Count and timestamp logging messages: disabled

File logging: disabled

Trap logging: level informational, 206 message lines logged

Logging to 10.14.9.1, 206 message lines logged, xml disabled,

filtering disabled

Logging to 10.14.9.19, 206 message lines logged, xml disabled,

filtering disabled



Why are messages to my syslog server being dropped (96 so far)?


Regards

Dan

As far as i know sylog messages will be dropped when


a) the router hasn't made a connection to the syslog server yet ie. when it is rebooting the router may try to send a syslog message before it has established a connection with syslog server


b) the syslog server has gone down.


Has either of these things happened ?

The syslog protocol uses port no 514. The destination port 514 must be open in any intermediate or terminal devices like firewall or router.

The syslog protocol uses port no 514. The destination port 514 (UDP) must be open in any intermediate or terminal devices like firewall or router.
