Gang:
Anyone know what the maximum amount of time an interface could transition from 'line protocol down' to 'line protocol up without triggering a STP topology change notification?
Reason I ask, I have a gigabit interface that is connected to a Cisco LRE CPE device that is transitioning from up-down-up at irregular intervals. However, no topology changes are being recorded via the 'sh spanning-tree detail' command. Additionally, although we can track the interface cycling on our end via the show log command, the Cisco LRE switch shows nothing in it's logs.
Any assistance appreciated
