Hi all, We use a search to turn on polling and alarming for all interfaces that show as connected in Spectrum, but we found a situation with frame relay interfaces where we have a sub-interface that is connected, but the physical interface is not. We have all the polling/alarming attributes set for the sub-interface and none set for the physical, except to alarm on traps (GeneratePortStatusAlarms=Off). When the physical goes down, we don't receive any traps (and no alarms were generated), the sub-interface is in a down condition, but suppressed. I'm wondering how others have modified their policy searches to account for this behaviour, or if there are any other suggestions on how to improve the alarming in this scenario. The event on the sub-interface would be: The link status of port (name - xx.xx.com_Se0/1/0.FrameRelayPort, type - FrameRelayPort) is now "bad" because it's lower-layer interface is DOWN. (0x10d16) >From Modeling Your IT Infrastructure Administrator Guide (5167) Devices that support advanced network technologies, such as Frame Relay and Link Aggregation, have logical entries in the ifTable representing higher layer interfaces. SPECTRUM models these logical layers according to the ifStackTable. When a monitored higher layer port goes down (such as a Frame Relay DLCI, or logical trunk interface), SPECTRUM will query the statuses of all lower layer interfaces before alarming the port which went down. If all of the lower layer interfaces are down as well, SPECTRUM will suppress the higher layer interface alarm. A key example is a physical Frame Relay interface going down which has multiple circuits provisioned on it. All of the higher layer DLCI port models will be suppressed, and the single red alarm will exist on the physical Frame Relay interface. Thank you, .....rod
