973.0. "Reliability Groups " by CSC32::CULP () Mon Apr 21 1997 17:19

    Hi All,
    
    I have a customer trying to implement reliability groups on a
    gigaswitch. Customer attempted to use reliablity group 37- 37:(12,16)
    SPN Port 12 and SPN 16. They also have inverted the bridge to only
    pass LAT, SCA traffic. When they enable reliability groups for failover 
    purposes the customer claims that LAT and SCA do not flow across the 
    FDDI link. When they remove the reliability group LAT and SCA work again.
    Customer is running 6.0 Clearvision Multichassis manager, 3.1
    Gigaswitch firmware. It is my understanding that the original ports
    12 and 16 have a copy of the same forwarding database and they are
    tagged to port 37, thus loosing there physical nature and becoming
    virtual.  Any thoughts would be appreciated!!

         They probably have the filters set up improperly.  Get them to
    provide the filter settings, and see if they have forgotten to set them
    for port 37.  Remember - any filters set before hunt group support
    (also reliablity groups) was added to the GIGAswitch/FDDI firmware will
    *not* include the virtual port numbers.  They don't magically expand to
    include those ports, you must specifically add them.

    Hello,
    
    Here's a follow-up on this issue that Kevin posted.
    
    Reliability groups and filtering works fine.  The customer
    (specifically the Telco) had the 2 fddi pairs going to separate
    concentrators in different central offices and this was the 
    configuration problem.
    
    Good Day,
