Same here. I think I've enabled SNMP on three or four of the 7000's.
We do ping every UE.....once every minute.
How did you correlate the polling with the dip in traffic? I want to
see if we get the same result here.

We are not using SNMP here just TR-069.
We do ping the UE.

Jeremy mentioned his periodic traffic dips to me recently off-list.
I have found the source of the dips, if not the final cause. For a
refresher, this was a 10-second long forced dip in traffic — nearly to
nil on the uplink, and 75-80% reduction on downlink. Easily replicable
by pushing iperf and watching interfaces as well as per-second
results.
ICMP+SNMP polling once per minute was causing them. My guess is still
that it's EPC related, as ICMP and SNMP results do get returned —
eventually. The poller puts out a peak of 600 pps for the whole
network, so the actual load for the LTE bearer ought to be much less
than that.
Anyone else doing ICMP or SNMP polling, perhaps at longer intervals?
(My guess is that we wouldn't have caught this at 5 minute intervals
or longer.)
