i would like to configure SNMP on our network. but
reduce network traffic for snmp queries as far as possible.
i did this on a testrouter so far.
but debugging snmp packets - i noticed that every 2 seconds a query
is sent - i attached an extract of the log-file.
our network now has about 40-50 routers - so if i will enable
snmp on all of these devices - that would result in a heavy network load,
isn`t it-
but so far - we do need such a strictly network mangagement- for now we do
polling every 40 minutes -
but when there is an outage on one of those devices, the customer notices it
prior to our
NOC.
so i configured snmp traps - which works fine - in an acceptable time - but
THAT didn`t reduce
my snmp queries floods, either.
so please could anyone give me an advice, how i could reduce these snmp
queries.
thanx
hans
