I have a switch with 4 Serial ports I monitor. I have an alert rule to send a trap if serial interfaces go down. The reset trigger is alert trigger no longer applies send a trap. Last night all four serial interfaces went down over a two hour period of time. Apparently, the Network Team rebooted the switch as part of their repair which triggered my node down alert. However, when the router came back on line, the only clear that was sent was the clear for the Node. I got no trigger resets for the interface alert.
Any thoughts on what might be missing from my alert trigger or that I need to add to the alert reset to account for a node reboot and subsequent interface restore after the Node up.
