Tags: tle simulates a trunk mode ace 51cto fast spanning tree quick typeLoops are present in the network, and all loops are formed due to confusion caused by ambiguous destination paths. 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

This article describes how to configure the IOS Firewall on a Cisco router. What should we pay attention to when configuring the firewall? The following article provides detailed answers.

that the admin domain is able to overwrite all branch switches. The Cisco switch is capable of supporting any media as a trunk, and it can use its own ISL tags for relaying. ISL (Inter-Switch link) is a protocol between switches, between switches and routers, and between switches and servers to transfer multiple VLAN information and VLAN data streams, configured with ISL encapsulation via ports directly connected to the switch, The VLAN allocation a
