Mvel snmpGet and snmpGetTable in self certification

    recently I came across strange Mvel snmpGet results. I dont know if Idoing everything alright or there is something I miss.

    If someone could confirm a bug or point my mistake please do so.

    Problematic code part is here:

     

    var oid_ap_mac          = "1.3.6.1.4.1.14179.2.2.1.1.1."+bsnAPDot3MacAddress.toString();

                                                     ap_mac_response         = snmpGet(oid_ap_mac);

                                                     ap_mac_instance          = ap_mac_response.getResult();

                                                     ap_mac_value               = ap_mac_instance.getValue();

                                                     mvelInfo({"ap_mac_value==",ap_mac_value,"ap_mac_instance==",ap_mac_instance});

     

    and the output in karaf log is:

     

    42 | 185 - com.ca.im.data-mgmt.common - 3.6.0.RELEASE-283 |  | MVEL info: ap_mac_value==,>ϊ�@   ap_mac_instance==SNMPResponseObject [value=,>ϊ�@, type=OCTET_STRING, index=null] 

     

    Note not printable characters above.

    First I though there is a problem with agent on a device BUT:

      - DCDEBUG search :

     

    uest [Initial Q position: 0 / Delay: 0 ms], Q Size: 0: GET[requestID=301768627, errorStatus=Success(0), errorIndex=50, VBS[1.3.6.1.4.1.14179.2.2.1.1.1.192.37.92.223.67.96 = Null]]

    Oct 05 06:06:27.472: Received SNMP response [Resp Time: 37 ms / Trans Time: 37 ms] evResponse:RESPONSE[requestID=301768627, errorStatus=Success(0), errorIndex=0, VBS[1.3.6.1.4.1.14179.2.2.1.1.1.192.37.92.223.67.96 = c0:25:5c:df:43:60]] evReque

     

    - SNMPwalk also is readable format:

     

    SNMPv2-SMI::enterprises.14179.2.2.1.1.1.28.222.167.239.246.128 = Hex-STRING: 1C DE A7 EF F6 80

     

    And now best part. When I do snmpGetTable 1.3.6.1.4.1.14179.2.2.1.1.1 I get this in karaf log

     

     

    SNMPGET TABLE RESULT[SNMPResponseObject [value=28.222.167.239.232.0, type=OCTET_STRING, index=28.222.167.239.232.0],

    SNMPResponseObject [value=192.37.92.223.67.96, type=OCTET_STRING, index=192.37.92.223.67.96]

    SNMPResponseObject [value=28.222.167.239.243.192, type=OCTET_STRING, index=28.222.167.239.243.192],

    SNMPResponseObject [value=28.222.167.239.244.192, type=OCTET_STRING, index=28.222.167.239.244.192],

    SNMPResponseObject [value=28.222.167.239.244.224, type=OCTET_STRING, index=28.222.167. 239.244.224],

     

    so this one looks alright. How come? Any ideas?

    what do I miss here?

    You're missing presenting relevant information for your question: what is it what you're trying to do? what's the table? what's the index? what's the VC? what's the MF?
