2748.0. "%system-f-ivchan" by LARVAE::AITKINS_T () Mon Apr 13 1992 09:49

    Hello fellow MCC people,
    			     I'm polling about 20 routers and keep getting
    exceptions generated with the message 
    
    Error assigning channel for link : status code=%system-f-ivchan
    			Invalid i/o channel.
    
    Could anyone explain this to me and/or advise on how to overcome 
    the problem. If I clear the alarm, and wait for the next poll somtimes
    it works OK.
    
    		       		Terry.

    Hi
    
    	It's DECmcc version 1.1 on VMS 5.4 and I'm polling the routers using
    the Phase iv access module. If I click on the router Icon I can see all
    of the circuits and I can do a show status from the iconic map on them
    individually without any problems.

    Hi,
    	I'm due to hand over DECmcc to the customer tomorrow 27th April,
    however due to the nature of this problem and that in note 2761, he has
    mainly a red map. Any advise welcomed.
    
    	Thanks in advance

2748.5fixed in v1.2TOOK::S_KOHoot mon!Mon Apr 27 1992 16:3013
    hello Terry,
    
    i am sorry for such a late reply.
    
    A bug was found in the V1.1 Phase IV AM that exhibits this
    behavior; it is has been fixed in V1.2.
    
    are the routers that you are polling single-link systems?  (that is,
    they only support one network management link).  Do you make multiple
    requests of the router?  If so, try staggering the requests so that
    they will not attempt to access the system all at the same time.
