> Is there default rate limiting of ICMP traffic in JunOS?

There is a default limiting of all the traffic to the RE.

Since you have a problem (missing ICMP echo replies while doing SNMP
queries) that *might* be due to such limiting, I would strongly suggest
that you do some packet sniffing and find out exactly what your NMS is
trying to do.

We have sizable Juniper M/MX based network here, and have never seen
the problem you describe - this is with a combination of commercial
monitoring systems and stuff we've developed ourselves. Mind you, we
don't have any EX switches.
