Layer controls the traffic on the Logical Link. This logical connection may span a series of data links.Application Layer, Session Layer, and presentation layer:The application layer corresponds to the OSI application layer, Session Layer, and presentation layer. Some routing selection protocols use this layer. For example, Border Gateway Protocol (BGP) and Route Selection Information Protocol (RIP ). However, the most common service in the applicati

Chapter IIIOne, managing Cisco IOS Configuration1 , there are two waysa , Runing-configthe current configuration command, which is saved in the RAM (volatile memory). Device power down, configuration is lost!!b , Startup-configSave the configuration to NVRAM (nonvolatile memory). No control device changes (restart, power off, etc.) configuration will not be lost!!router#copy runing-config startup-config----- Save the current configuration to NVRAM inO

Configuration of single-arm routing and DHCP for Cisco devicesIn this experiment, we will configure single-arm routing and DHCP to enable the PC to automatically obtain IP addresses and achieve network-wide interconnection. Tutorial steps: 1. configure the IP address and gateway of the PC. add different VLANs to the vswitch and divide different network segments f

One, virtual local area network (VLAN)At present, the backbone network technology used in constructing enterprise network is based on Exchange and virtual network. Switching technology changes the shared media to exclusive media, greatly increasing the network speed. Virtual network technology to break the constraints of the geographical environment, without altering the physical connection of the network can arbitrarily move the workstation between the workgroup or subnet, workstations composed
