4799.0. "Can't read Ring Error Reason attribute" by PRSSOS::BONNAFE (Guy BONNAFE - CSC France) Thu Apr 01 1993 12:28



	I'm unable to manage 'ring error reason' characteristic on a DECnis 
version T2.1.53 with DECmcc V1.3 SSB : I checked the dictionary and I found that
it is well implemented. I can read all others characteristics on this subentity 
but not this one.

Any idea ?

Regards,
Guy.

4799.1reason code undefinedTOOK::S_KOHoot mon!Fri Apr 02 1993 16:244
    
    Ring error reason 240 is not defined in the MSL.  The PM is reporting
    that it cannot find the information in the dictionary to format the
    output (the code is translated to a text string).
4799.2Data type problem ?PRSSOS::BONNAFEGuy BONNAFE - CSC FranceTue Apr 06 1993 06:3914



	Thanks for your reply Stella.

	My feeling is that the way to encode 'ring error reason' attribute is
	different for DECnis and DECmcc softwares. Combination of set bits in
	DECnis and enumeration data type for DECmcc. So 240 could be a
	combination of bit 9 and bit 6 from one part and nothing to the other.

	It would be interesting to have a DECnis/FDDI/CMIP specialist advice 
	on this.
	Guy.

    It looks like the DECnis is treating this attribute as a bitset
    but the DSSR registered definition is of type enumeration.
    I'll send mail to a DECnis engineer and see what he says.
4799.4Not as subtle as thatMARVIN::COBBGraham R. Cobb (DECNIS development), REO2-G/G9, 830-3917Wed Apr 07 1993 09:0512
We are  just  returning rubbish for this attribute.  A value returned by the
device  firmware is making its way all the way up to network management with
no  piece of code mapping it into the architected values.  In fact, it looks
like  we are not even using the right field of the data structure the device
provides!  It appears that the value we return is always either 0 or 240.

Expect a  fix in DECNIS V2.2.  If you want to track progress yourself, enter
a  DECNIS  QAR.  If you have a customer who *needs* a fix sooner than DECNIS
V2.2 (summer) you will need to raise a CLD against DECNIS.

Thanks for reporting this.
Graham
