174.0. "%MCC-E-ILVTNF error when trying to access a bridge" by BEAGLE::LORPHELIN (Chr Lorphelin TSCG/VBO) Mon Jul 09 1990 09:33

    I am getting from time to time ILVTNF error when trying to access
    any registered bridge.
    
$ mana/ent
DECmcc (T1.0.1)

show bridge vit_algo line * all spann char
BRIDGE NESEVO_NS:.vit_algo LINE 
Spanning Characteristics
AT  9-JUL-1990 10:43:33


The requested operation cannot be completed
                      MCC Routine Error = %MCC-E-ILVTNF,  specified tag not 
                                          found within current constructor 
    
    
    BRIDGE_AM is correctly enrolled.
    To be able to reaccess one specific bridge I found a very unpractical
    workaround :
    - deregistering of bridge
    - REregistering of bridge 
    
    Strange isnt't ?

    RE: %MCC-E-ILVTNF error when trying to access a bridge
    
    Could you drop a reply into this note with answers to the following
    questions (I would greatly help us RE this problem):
    
    1. Please issue the command "SHOW BRIDGE vit_algo HARDWARE TYPE"
       and tell us what type of bridge (are we talking TRANSLAN?).
    
    2. Does this problem ever occur with either of the following:
         a) SHOW BRIDGE vit_algo LINE 1 ALL CHAR ?
         b) SHOW BRIDGE vit_algo LINE * ALL CHAR ?
    
       (yes, I do mean ALL CHAR above, and not ALL SPANN CHAR)
         
    3. Does the problem ever occur with the LINE specified explicitly
       (e.g. SHOW BRIDGE vit_algo LINE 1 ALL SPANN CHAR) ?
       If so, does it occur with a specific line (e.g. a DISABLED line,
       a non-ethernet line) or with different ones randomly?
       If you can isolate a failing line, please issue the command
       SHOW BRIDGE vit_algo LINE <failing-line> ALL ATTRIBUTES and
       post the results as a reply to this note.
    
    I suspect that the source of this problem may be the way Attribute
    Groups are being handled by the FCL PM (i.e. FCL *may* be requiring
    all attributes associated with a GROUP to be returned in a PARTITION
    and failing on a missing attribute), but providing the information
    above will help isolate it.
    
    Thank in advance for any assistance!

174.2%MCC-E-ILVTNF error when tryning to access a bridgeBEAGLE::LORPHELINChr Lorphelin TSCG/VBOThu Jul 12 1990 14:1238
	Chris,
	Thanks a lot for your detailed answer.
	Since I rebooted I don't experience this problem again !
	If problem comes back I shall follow strictly the procedure
	you suggest.
	Anyhow I can partially answer to your questions :

>>>>  1. Please issue the command "SHOW BRIDGE vit_algo HARDWARE TYPE"
>>>>       and tell us what type of bridge (are we talking TRANSLAN?).
	RE: Vit_algo is a vitalink Translan III .
            But I tried this command on LB100s and got same results.
	    More precisely from the moment I got this message for one
  	    specific bridge I got it for any of my bridges.
		{ LB100s and TRanslan III }.
	    DEREGISTERing them and reREGISTERing them again fixed 
	    problem.

	RE: Sorry I didn't try this command !

>>>>	b) SHOW BRIDGE vit_algo LINE * ALL CHAR ?
>>>>       (yes, I do mean ALL CHAR above, and not ALL SPANN CHAR)
	RE: YES ! and I got problem.

	I tested SHOW BRIDGE COMMS
	  then   SHOW BRIDGE COMMS ALL REF
	  then   SHOW BRIDGE COMMS ALL STATUS
	  then   SHOW BRIDGE COMMS ALL CHAR
	  then   SHOW BRIDGE COMMS LINE * ALL CHAR
	  then   SHOW BRIDGE COMMS LINE * ALL STATUS
	  then   SHOW BRIDGE COMMS LINE * ALL SPANNING CHAR

	  And I got "the problem".
	  { COMMS is a LB100 }.

174.3groups don't require all attrsGOSTE::CALLANDERThu Jul 12 1990 16:4611
    
    Chris,
    
    As an FYI. The PM does not require all attributes in a group be
    returned. Instead it looks for them and if not present, simply
    continues on with the next expected attribute. The behavior you
    were wondering about, a group returning an TNF, was reported an
    corrected in baselevel X0.09.

174.4Idle speculation...CHRISB::BRIENENChris Brienen - DECmcc (non-DECnet) AMsThu Jul 12 1990 18:177
    RE: Jill (Note 174.3 by GOSTE::CALLANDER)
    
    Thanks for the update (guess my "speculation" was incorrect).
    
    RE: .2
    
    Rebooting removed the problem? That's *wierd*...
174.5Did you flush namespace for EFTupdate?TOOK::STRUTTColin StruttFri Jul 13 1990 01:368
    This is a wild guess, but you reported that the problem went away when
    you deregistered and then (re) registered the bridge.
    
    Did you "clean out" the name space when you put up the EFTupdate
    version, as recommended in the Release Notes? The namespace set up by
    versions prior to FTupdate are not compatible with those now used.
