LMS 3.2 Dynamic UT Incorrect OID

When I configure 3550 with mac-notification snmp traps to enable Dynamic User Tracking, I got incorrect OID in the macuhic.log and nothing happens with UT:

class com.cisco.nm.cm.ut.uhic.mac.AsnDecoder.AsnObject: CB-Error-incorrectoid: Skt IP Address: 10.128.145.17, Incorrect OID: 1.3.6.1.4.1.9.1.485, location ctxt: AsnMakeMe_snmp_v1, SNMPv1
Decoder Stage: deviceIP : null  timeStamp : 0  Processed : false
class com.cisco.nm.cm.ut.uhic.mac.AsnDecoder.AsnObject: CB-Error-incorrectoid: Skt IP Address: 10.128.145.17, Incorrect OID: 1.3.6.1.4.1.9.1.485, location ctxt: AsnMakeMe_snmp_v1, SNMPv1
Decoder Stage: deviceIP : null  timeStamp : 0  Processed : false

All is working well on these 3550s with LMS.

Please Help ?

Thanks in advance,

Patrice

Re: LMS 3.2 Dynamic UT Incorrect OID

You asked this in https://supportforums.cisco.com/thread/176483 .  I summarized the problem there as it was affecting the original poster.

Campus will only handle cmnMacChangedNotification traps.  If your switch is not generating these, then Dynamic UT will not work.  A sniffer trace filtering on udp/1431 will confirm the traps being received by Campus.

Thanks Joe.

LMS is configured to get traps on udp/1431.

So, I will take a look on these received traps.
