Web30 Oct 2024 · BPDU GUARD and PORTFAST: when we enable port fast on any port then the port changes our STP behavior like the below: 1. Port saves the STP converge time from 30 sec to 2 sec. (STP port converge time). 2. Port goes direct forwarding state. (not goes blocking> Listing>learning directly in Forwarding) 3. Spanning Tree Protocol (STP) resolves physically redundant topologies into loop-free, tree-like topologies. The biggest issue with STP is that some … See more Internally, STP assigns to each bridge (or switch) port a role that is based on configuration, topology, relative position of the port in the … See more CatOS 1.

Technical Tip: STP forwarding - Fortinet Community
WebIt's a means of redundant uplinks via different paths, and only detects those kind of loopbacks. Proper loopback detection is a separate feature in other brands. I have seen a faulty dumb switch trigger STP in a Cisco switch before, taking down the whole phone system for a large company. Web10 Oct 2008 · 01-Jan-2000 00:01:42 %STP-W-LOOPBACKDETRSLV: g21: STP Loopback Detection resolved. I don't understand because there are only the network (port 21) and my computer which are connected so no loopback possible. There is the same problem with the second switch, so i think it isn't an hardware problem. name rater gsc

One such feature is … Web28 Oct 2024 · Loop protection is an enhanced function of STP. It prevents loops that occur when a port cannot receive BPDUs from the upstream switching device. In addition to loop protection, STP supports enhanced functions such as root protection and BPDU protection.
