WebApr 6, 2015 · Standard spanning tree protocol has an unfavourably long convergence time. Note that this may also have a detrimental effect in situations where the design is loop-free, in other words in a pure tree structure. If one inadvertently creates loops, this will hinder traffic for an unnecessarily long time when standard spanning tree is implemented. WebIn my case, the network is WORKING. If spanning tree was OFF, and I had a network loop, it would stop working. With spanning tree ON, it theoretically would keep the network working, so how would I know that there is a problem loop for example, since the equipment would mask the issue? (the answer above about snmp/logs so far makes sense)
