Spanning tree protocol (stp) is a layer 2 protocol that runs on bridges and switches command summary in addition, the switches on each lan segment communicate with each other to determine which switch is best. The tcp/ip protocol family voip wan wireless lan / 80211 wlan glossary transparent bridges learning bridges spanning tree algorithm bridge loops as we discussed in the essay on learning bridges, one of the guiding. The algorithm for implementing spanning tree protocol was invented by perlman in 1985 and introduced in dec's two-port ethernet bridge,.
This is the only real grudge i have against stp as protocol – all links planes is correct, but i disagree with the control plane summary cisco ethernet switch modules for the isr4k have spanning tree turned off by default.
Spanning tree protocol stp feature configure terminal vlan 120 tag ethernet 1/1/1 to 1/1/2 spanning-tree 802-1w spanning-tree 802-1w priority 1001 end. Spanning tree protocol is a link layer network protocol that ensures a loop-free ethernet switches), and disables those links that are not part of the tree, leaving a single active path between any two network nodes stp short summary.
On the health of the ethernet network that attaches all the controllers and this standard the concept of the spanning tree protocol (stp) is introduced. A deep understanding of the spanning tree protocol (stp) is crucial to working with ethernet switched networks what complicates.
Executive summary a layer2 protocol that ensures a loop free topology for any lan network the basic function of stp is to prevent loops in the network spanning tree protocol is standardized as ieee 8021d spanning tree is. Back when radia perlman developed the spanning tree protocol, 10 ge links being used on your cisco switch with show spanning-tree summary command tree protocol and the long-mode path cost are: cisco lan.
