When a BIG-IP generates SNMP OID-required truncation in order to stay within the OID max length limit of 128, the truncated OID is not always consistent or unique.
SNMP get, get-next, and set commands might fail or even operate on incorrect data when the target OID is not consistent or unique.
An SNMP table has a unique index (key) consisting of one or more table attributes of various types. String type index attributes with values lengths approaching or exceeding 128 characters expose this truncation issue.
The long string values triggering this issue are typically identified as user-supplied names that were introduced as part of BIG-IP configuration. Often these names can be reconfigured to a shorter length.
Truncated OIDs are now appended with a unique check-sum value that remains unchanged from one query to the next.
