3897.0. "Alarm on fddi-station entity" by PRSSOS::BONNAFE (Guy BONNAFE - CSC France) Tue Oct 13 1992 14:55

DECmcc/Ultrix V1.2 
ELM package

The MCC command :
	MCC>show fddi-station test_fddi SIF CONFIGURATION phy port conf , -
	_MCC>in domain = fddi_ring_map
displays the following result :

FDDI-Station KBANON_NS:.test_fddi SIF CONFIGURATION
AT 13-OCT-1992 18:44:01 Characteristics

                 Phy Port Configuration = ( (
                        Port Resource Index = 1,
                  Connection Resource Index = 2,
                                  Port Type = Slave,
                           Remote Port Type = Master,
                                 Port State = Active,
                                 Remote MAC = False ) )

Is there a way to display only one of the individual characteristics, say
'Port State' ?? I can't find the right syntax.
By checking the DECmcc dictionary, I've found that 'Phy Port Configuration' is
the attribute of a specific type ( CONSTRUCTOR_DATA_TYPE ) : 'Port State' is
only a definition of this type, a kind of field in a record. 

The goal is of course to define an alarm on one of the characteristics,
tipically the 'Port State'.

Guy.

    No, there isn't.

    With the bridge and concentrator Device Configuration attribute, which
    is also a record, we added an attribute called Device Configuration
    Error Condition.  An alarm can be set on that new attribute, and then
    the alarm message can instruct the network manager to check Device
    Configuration for the actual error.

    Is Port State the only thing you would like to set an alarm on?  If you
    can make a list of all the alarm conditions you would like to see for
    the FDDI record structures, we might be able to add some new
    synthesized attributes to set alarms on.

    This is *clearly* a wicked bad kludge we had to do in order to get
    around an obvious shortcoming of MCC.

    The Alarms FM should find a way to address fields within a record. 
    That might mean that the PMs need attention to fix this problem, so you
    can Show a specific field within a record.

    It's gross that the AMs need to be hacked like this to get around the
    problem.

Ed,

Let me try to summarize my thoughs :

Concerning DEC equipments, the following command :
        MCC>show bridge <bridge_name> phy port 1a Phy Port State
allows me to test the attribute 'Phy Port State' which can be used to set an
alarm.
For non-DEC equipments, if we don't have the same level of information via
the fddi-station AM, we are forced to use the SNMP AM and test an attribute
named 'snmpFddiPortConnectState' which can also be used for the alarm.
With the next version of firmware for both bridges and concentrators, the 
SNMP attribute 'snmpFddiPortConnectState' will be implemented because the
standard FDDI MIB will be used, replacing the experimental one. Allowing me
to manage all my fddi equipments in the same way : snmp instead of elm.
That's why I think that we need a way to set alarms on attributes from the
fddi-station entity. And I agree with you : we have to do this through an access
to individual fields in the records, not by defining 'glogal' attributes.

Guy.
