Symptoms
How does Smarts name interfaces?Interface names from Smarts AM discovery do not appear to be correctDisplay name of interface discovered by Smarts AM does not match Interface Description
Cause
The system is functioning as designed. Interface names will often not match the Interface Description field because Smarts Availability Manager (Smarts AM) discovery uses the IfName OID to name interfaces, and not the IfDescr OID.
Resolution
Smarts AM discovery uses the IfName OID (.1.3.6.1.2.1.31.1.1.1.1) to name interfaces and not the IfDescr OID ( .1.3.6.1.2.1.2.2.1.6) because IfName is a read-only OID and therefore more reliable. The IfDesc OID is modifiable and therefore cannot be reliably consistent.
Related Information
Example The DisplayName for the interface could be the following: IF-focus/1 [AT4/0] [ATT DNEC922998 DS3 link] While the Description for the interface could be the following: ATM4/0
