Loop detection in core switches
The mechanism immediately generates a log when a loop occurs so that you are promptly notified to adjust network connections and configurations. Network loops occur when there are multiple paths between two points in a network, leading to data continuously circulating and potentially causing significant issues such as performance degradation, unexpected port blockages, complete network outages, and device crashes. Loop detection on 5120-SI switches Hi! Recently we had a loop in one of our VLANs in our HP based network (10500 core-switches, 5120-SI access switches). Hi Janrovner, Feature is called "persistent-learning" on Juniper, essentially identical. Now at most of our sites we use Extreme, which has a handy feature called ELRP Extreme Loop Recovery Protocol, despite the name, this mechanism just detects loops, in the logs we can see, ok. It continuously monitors traffic to detect scenarios such as a port receiving its own transmitted packets due to miswiring, or a direct link loop formed when two interfaces—either on the same device or.
