Trying to change the "read-only" node through snmpset

[vvsosed]

If we call "snmpset -m ALL -v2c -c private 10.40.0.149 IF-MIB::ifOperStatus.4 i up" in the result we get:

MH-N366@00000000>show compare running-candidate 
+IF-MIB:IF-MIB {
+    ifTable {
+        ifEntry 4 {
+            ifOperStatus up;
+        }
+    }
+}

But ifOperStatus (in IF-MIB.yang) declared as "read-only" in yang model:

leaf ifOperStatus {
    type enumeration {
        enum "up" {
            value "1";
        }
        enum "down" {
            value "2";
        }
       ....
    }
    ...
    smiv2:max-access "read-only";
    smiv2:oid "1.3.6.1.2.1.2.2.1.8";
}

I consider that in this case, the clixon_snmp module must decline operation taking into account the smiv2:max-access value and also it mustn't prepare any changes in the candidate database
