When configuring a new switch in a packet-switched network, Spanning tree helps protect against network loops.
Network loops can occur when there are redundant paths in a network topology. These redundant paths can result in the creation of multiple copies of the same packet being transmitted in the network, leading to congestion and ultimately a network outage.
Spanning Tree Protocol (STP) is a network protocol that helps prevent network loops by disabling redundant links in a network topology. STP achieves this by creating a logical tree-like topology that eliminates any loops in the network.
When a new switch is added to a network, STP helps ensure that any redundant links created are automatically disabled, ensuring that only the primary link is used for forwarding packets. This helps prevent network loops from occurring, improving the overall stability and performance of the network.
Flood guard, BPDU guard, and DHCP snooping are all additional security features that can be used to enhance the security of a network, but they do not directly address the issue of network loops.
