4129.0. "CABLETRON & ASN1 description pb" by ZTOIS1::VISTA (Renato VISTA, SIS Strasbourg, France) Mon Nov 23 1992 13:45

    
    Hi,
    
    I'm working on a DECmcc/ULTRIX/BMS V1.2.0. I want to manage CABLETRON
    IRM2 Management Board.
    
    When I do the following command :
    
    MCC>show SNMP plm0csh1 cabletron commsDevice commonP * all attr
    
    ...I get...
    
    SNMP plm0csh1 cabletron commsDevice commonP (1,1)
    AT 1992-11-18-17:36:13.996 All Attributes
    
    
                              commonP_Index = ( 1,
                                                1 )
                                  portIndex = 1
                              portMediaType = 176
                             portAdminState = on
                             portSourceAddr = -- Attribute Not Gettable
                                                                                  
    ...More than 500 instances are expected...Nevertheless, portSourceAddr
    variable returns no data.
    
    Then, I use the mcc_tcpip_mq utility, ie :
    
    
    


    FOR BOARD 1, PORT 1 (IRM2 front port), Variable portSourceAddress, 
    Datatype OCTETSTRING, please note that :
    
    	- portSourceAddress is not an occurrance description
    	- there is an unexpected index (datatype Integer)...reaching a
    	value overflow (255 to 0 !!!). This overflow provokes an error.

... A LOT (!!) OF SAME MESSAGES...

    In conclusion, the question is :
    
    Is a normal way of using ASN1 final variable (no occurrance description
    expected) by CABLETRON private MIB & remote IRM2 Agent, sending to the
    portSourceAddr (datatype OCTETSTRING) variable more than one instance
    of HW address ?
    
    Is it a snmp/mcc_tcpip_mq (or other NMS platform) of indexing by
    default with an index (datatype integer [0..255]) during such a SNMP
    query ?
    
    Thank you for your replies.

    PS : NAT/NMS PC-based software has the same behavior and meets the same
    kind of problem.
