WebUpon a power-cycle, a broadcast storm took down the network and originated from these two switches. channel-group 1 mode on was configured on all ports. From my research L2 etherchannel links should be configured with only channel-group 1 mode desirable L3 links can be configured w/ channel-group 1 mode on as STP isn't running over them. WebFeb 9, 2024 · The spanning tree protocol (STP) was introduced into the networking world as a means to prevent layer 2 network loops (frame broadcast storms) from disrupting the service of a local area network. STP uses clever mechanisms to prevent loops by virtually disconnecting redundant links.

It does this by detecting a loop in the topology and will actively block traffic over one or more of the links if a loop is detected. This takes some thought to do right and can be different per VLAN depending on which version of STP you are running. how many photos on 64gb card

"WebJan 10, 2024 · The primary function of the spanning-tree algorithm (STA) is to cut loops that redundant links create in bridge networks. The STP operates at Layer 2 of the Open System Interconnection (OSI) model. By means of bridge protocol data units (BPDUs) that exchange between bridges, the STP elects the ports that eventually forward or block traffic. " - How does spanning tree prevent loops

WebFeb 17, 2024 · A spanning tree is the result of a DFS traversal of a graph. A graph with no loops is known as a spanning tree. We use a Stack data structure with a maximum size equal to the number of vertices in the Graph to implement DFS traversal. To implement DFS traversal, we take the following stages. WebThe number t(G) of spanning trees of a connected graph is a well-studied invariant.. In specific graphs. In some cases, it is easy to calculate t(G) directly: . If G is itself a tree, then t(G) = 1.; When G is the cycle graph C n with n vertices, then t(G) = n.; For a complete graph with n vertices, Cayley's formula gives the number of spanning trees as n n − 2.
