The loop has a great impact on the network. Spanning Tree protocol is a good solution to this problem.The idea of spanning a tree protocol topology is that, regardless of the physical connection between switches, the switch can automatically discover a network with no loop topology, and the network of the logica

Cisco CCNA Chapter 4 answers in the second semester, Cisco ccna second semester 1. 2. All the routers running the Distance Vector Routing Protocol have disconnected all power supplies (including spare batteries ). What happens when these routers are reloaded? They share all route information stored in NVRAM before the power-off with the directly connected neighbor

"Introduction" Cisco switch Catalyst 3750-e Series production in 2007, the original system is very old, in order to let it out of the spring, we can upgrade its system. Pre-upgrade preparationFirst we need a new version of the Catalyst 3750-e Series Cisco switch ISO file, online searchable to many, here we recommend a 2015-year version of the download link is:Cisco switch Catalyst 3750-E Series ISO (2015)Th
