syslog messages via snmp-

I'm still trying to understand this command:

snmp-server enable traps syslog

I think this will send log messages via snmp to the snmp host configured in the snmp-server host statement.

Is there a way to pick and chose which messages or message severity levels you want sent to the snmp-server host?

That is correct.

Re: syslog messages via snmp-

You are correct, the syslog messages will be converted into snmp traps (as defined in the CISCO-SYSLOG-MIB) and sent to the ip address listed in snmp-server host

The severity is controlled by the logging trap command.

Let me make sure I have this part correct. The only control of what syslog messages can be sent to the snmp-server host is by syslog severity levels?

I can't send some messages from a severity level 3 and not others? It's an all or none situation I'm guessing.....

That is correct.

Re: syslog messages via snmp-

I guess this is what the guy was talking about on how only specific syslog messages could be selected and sent....

event syslog pattern regular-expression [occurs num-occurrences] [period period-value] [priority priority-level] [severity-level]

I'm sure there are a number of requirements before this can happen and the code must be at a certain level.....

Re: syslog messages via snmp-

Hi!

I think what you are asking is:

When the device sends a syslog message also as SNMP trap (snmp-server host ... syslog) how can I specify what syslog message is send as trap.

the config command on the device would be:

device(config)#logging history ?

<0-7> Logging severity level

alerts Immediate action needed (severity=1)

critical Critical conditions (severity=2)

debugging Debugging messages (severity=7)

emergencies System is unusable (severity=0)

errors Error conditions (severity=3)

informational Informational messages (severity=6)

notifications Normal but significant conditions (severity=5)

warnings Warning conditions (severity=4)

So if you want to receive syslog traps only for syslog error messages then configure:

device(config)#logging history 3

I hope this is what you were looking for.

Cheers,

Marco
