1507.0. "DECmcc or Netview to manage HUB900" by EEMELI::SETALA () Fri Sep 30 1994 11:20

        hi,

        one of our customer which have mcc want to know if you can
        set alarms for hub modules. For examles they want to check
        line counters(error, packet rate and utilization) of
        ports of repeaters an bridge's.

        They are planning to buy more HUB900's if they can setup alarms
        for hub modules. They will buy hub's from someone else than
        Digital if they can't setup alarms by using mcc or Netview.

        The customer think that it is not enough that they get
        SNMP trap for example if some port is dissabled.
        They want to check counters too. Customer don't want to
        look HUBwatch they want to have automatical alarms which
        send messages by mail or to pager. So HUBwatch will not
        be the whole answer.

         If it is easier to setup alarms by using Netview that's okey
        because then they will change mcc to Netview.

        cheers

	Matti, This is really an Mcc/Netview issue. Network Management Stations (NMSs) typically allow alarms to be set-up by having the user specify the objects which are to be monitored, poll rates, thresholds, and other stuff. Some NMSs allow complicate formulas to be applied to the objects being monitored. I don't know about Mcc, but I know Netview has a pretty sophisticated alarmer. DEChub products support a lot a SNMP objects. You could find many useful things to alarm on. So yes, they can "check line counters(error, packet rate and utilization) of ports of repeaters an bridge's". I you tell me what, specifically, your customer is interested in setting alarms on then I could point you to the appropriate objects to monitor. By the way, some of the "next wave" products will support the RMON Alarm and Event group. This provides a convenient and standard way to set alarms. Also, your customer might be interested in the DECpacketProbe module. -Shawn
1507.2	More from the same customer !!	EEMELI::SOHLMAN	Jouko Sohlman , NIS Helsinki Finland	`Thu Oct 06 1994 10:11`	13
	Hello ! When the author of the .0 is on his well earned vacation I am passing this question for him. The question is the same as in .0 but this same customer has also some old DEChub90's with DECagent90's. Is there a way to do the same as in .1 with this old stuff also?? Thanks in advance Jouko
1507.3		NETCAD::GALLAGHER		`Thu Oct 06 1994 10:28`	13
	Yes. Since this is an NMS feature you should be able to set alarms on any SNMP device. The DEChub90 also has an extensive private MIB with many objects worth monitoring. There is one added wrinkle with the DECagent90 though. You need to be aware of the poll interval the DECagent90 is using. The DECagent90 is capable of managing both local and remove devices. (Remote hubs must have a DECbridge90.) The DECagent polls objects in the devices, and puts the results in its MIB. If it's polling objects at a rate of once every N seconds, then your NMS probably shouldn't poll these object more frequently than every 2N seconds. -Shawn
