IOS-XR SNMP Interface Spikes

[manuels11]

Hello,

can anyone confirm this strange behavior @ SNMP.

The spikes are only in SNMP on all interfaces at the same time. No spikes if i monitor the interface on the Router.

SNMP collected with telegraf>influxdb>grafana but the same problem if i use other collectors.

Have IOS-XR SNMP request/send limits?

running on ios-xr 6.4.2

Best Regards.

We've seen similar traffic on different interfaces in the past, and suspect it is a buffering event of some kind in the attached device.  We don't see this behavior in 9K-9K backbone traffic, even at high rates.

do you have "snmp-server ifmib stats cache" configured? i have seen gaps/dips before which can be resolved by adding this feature
