MX80 Strange SNMP Issue

‎02-18-2017 02:23 PM

Yesterday suddenly an SNMP issue started on our router

Sometimes our router response completely to SNMP requests , but most of the time not. There was no issue like this until yesterday it happened suddenly 🙂  Any body faced an issue like that , we removed all snmp rules except  1 and still the same :

 

 

set snmp community XXXxxxXXX authorization read-only

And also strangely we have routing-instances , if i send request like r2@XXXxxxXXX  it returns a complete snmp result for the routing instance.

 

There is nothing in messages wrong and we traced also there is nothing listed,

we try to connect from L3 port / from routing instance / from bridge domain edge ....etc.  nothing change
