WebThe Spanning Tree Protocol (STP) is a network protocol that is used to eliminate bridge loops in Ethernet LANs. STP prevents network loops and associated network outage by blocking redundant links or paths. The redundant paths can be used to keep the network operational if the primary link fails. WebNov 9, 2024 · Loop avoidance – For redundancy, two switches are connected to each other through two links which can also result in layer 2 loops. These loops are avoided by switching by using the STP (Spanning tree protocol) protocol. Note – An entry in the switch MAC table, also known as CAM (Content Addressable Memory), can remain up to 300 …

WebOct 8, 2024 · ALL switch networks have loops. If they have no loops then they have no redundancy, and we like redundancy. It's important to learn to differentiate between loops at Layer 1 and loops at Layer 2. Loops at Layer 1 are required. They are controlled/manipulated at Layer 2 by spanning-tree and the network engineer knowing his or her stuff. WebSep 5, 2024 · You can control your loops with the break and continue statements. Break Statement In Go, the break statement terminates execution of the current loop. A break is almost always paired with a conditional if statement.
