In all places where ``community at router'' is accepted, you can add additional
parameters for the SNMP communication using colon-separated suffixes. The
full syntax is as follows:
community at router[:[port][:[timeout][:[retries][:[backoff][:version]]]]]
where the meaning of each parameter is as follows:
port
the UDP port under which to contact the SNMP agent (default: 161)
timeout
initial timeout for SNMP queries, in seconds (default: 2.0)
retries
number of times a timed-out request will be retried (default: 5)
backoff
factor by which the timeout is multiplied on every retry (default: 1.0).
version
for SNMP version if you have a fast router you might want to put a '2' here.
This will make mrtg try to poll the 64 bit counters. And thus prevent
excessive counter wrapping. Not all routers support this though.
Example:
3:public at router1:::::2
