1813.0. "decconcentrator 500 trap description" by GIDDAY::POPPINS () Mon Sep 25 1995 00:45

    Hi all,
    	I have a customer with a FDDI ring consisting of DECconcentrator500
    and a CISCO 7000. The problem is that at intermittant intervals the
    HP OpenView station reports that the DECconcentrator500's go through a
    warm restart e.g. 
    "T 3342    0.02407  [134.18.80.50]  [134.18.225.2]   SNMP Trap Warm
    start".
    This is accompanied by end-station's freezing and then
    continuing so I believe that this is a real event on the ring. I have
    tried to find a definition of the warm restart trap from a
    DECconcentrator500 but have been unable to do so.
    
    1) Could some kind soul put a good, precise description of the conditions
    under which a DECconcentrator500 would generate a "warm Restart" trap.
    2) Does a document exist, in the same way that a MIB definition exists,
    of the traps which the older FDDI products generate.
    
    thanks in advance

    Examining the diagnostic block using manufacturing diagnostic mode:

    Power off the concentrator.

    Connect a terminal to the OBM port of the concentrator, 19,200 baud.

    Connect a jumper on the left most two manufacturing pins, the three

    I'm unaware of a document. The DECconcentrator should support coldstart, 
    warmstart, linkup, phy events (connect (port active), disconnect 
    (standby, disabled, connecting)) and authenticity traps.
