Cisco router configuration manual Virtual LAN (VLAN) routing 1. The main network technology we currently use when constructing an enterprise network is generally based on exchange and virtual networks. The exchange technology changes shared media to exclusive media, greatly improving the network speed. The Virtual Network Technology breaks the restrictions of the

Technical standards for VLANs IEEE 802.1Q was formally promulgated by IEEE Commissioners in June 1999, and the earliest Vlna technology was proposed by Cisco (Cisco) companies in 1996. With the development of the past few years, VLAN technology has been widely used in large and small enterprise networks, becoming the most popular Ethernet LAN technology at presen

An instance of VLAN configuration for Cisco L3 switches and L2 SwitchesCisco VLAN implementation is usually port-centric. The port connected to the node determines the VLAN in which it resides. There are two ways to allocate a port to a VLAN: Static and Dynamic. The process

Branch switches.The Cisco switch can support any media as a trunk line. To achieve relay, you can use its unique isl tag. Isl (inter-switch link) is a protocol for transmitting vlan information and vlan data streams between switches, between switches and routers, and between switches and servers, by configuring isl encapsulation on the port directly connected to

with no VLAN tag in the Ethernet packet. The value of the tpid is fixed to 0x8100, which indicates the type of 802.1Q that the network frame hosts, which the switch uses to determine that the data frame is appended with IEEE 802.1Q-based VLAN information. The VLAN ID, in essence, is the 12-bit element in TCI. With a total of 12 bits, it is possible to identify u

Cisco single-ARM routing configurationOne-arm routing, which is to set up multiple logical subinterfaces on the router, one VLAN for each sub-interface. The data on each sub-interface is passed on the physical link to be labeled encapsulated. Cisco devices support ISL and 802.1q (dot1q) protocols. Huawei only supports

to say, after you set the password for level 1, you will be asked to enter the password next time you connect to the switch and enter K, this password is the password set for level 1. Level 15 is the privileged mode password that you enter after you enter the enable command. Step 2: Set the VLAN name. Because the four VLANs belong to different switches, the command for VLAN naming is
