    How does Spectrum count/calculate availability for device vs interface for general understanding? Notice Spectrum port availability had 7 hours downtime for a node (interface contiuously bouncing over extended period of time) but the device had 2 days 11 hours of downtime (interface was bouncing continuously good port of those 2 day) 

     

    We have CA Perf. Management which distinguishes between availability as defined strictly by device uptime counter which is back filled if wan interface is down but device has power versus "reachability" ability to get an ICMP response from device. 

     

    Thanks.

    Hi Jon,

     

    Availability reports in Spectrum use the up/down time of the device along with calculating in business hours and maintenance mode. There should be a drop down menu to use a global collection if I remember correctly. For WAN interfaces I believe they would need to be in a Global Collection also.

     

    The below doc goes over this in also.
