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
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
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 comm

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 betwee
the ports of the corresponding vswitch as required in table 1. To verify our configuration, you can use the show vlan command in privileged mode to display the configuration you just made and check whether it is correct.
The above describes the VLAN configuration of the

3550 Ports 1-8 are allocated to VLAN 2, ports 9-16 are divided into VLAN 3, and ports 17-24 are allocated to VLAN 4.

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
I am eager for the first time to switch between vlan routing and nat addresses of Cisco switches. I am very energetic and have an undefeated spirit. I am ready to continue to answer questions during multiple rounds of interviews. My little brother squashed his eyes and took out the bottom of the press box: If my company has two Internet interfaces, A and B, respe

[Cisco] DHCP relay, layer-3 Switch VLAN Routing PracticeThe experiment topology uses the GNS3 0.8.6 simulator to build a DHCP server using Red Hat 6.5. The experiment requires configuring a layer-3 Switch VLAN routing so that VLAN10 and VLAN20 members can access each other.
After decades of development, from the first four-node ARPANET to the ubiquitous Internet, computer networks have penetrated into our lives. With the explosive growth of the computer network scale, as a router to connect devices also become more important.
When a company builds a network, how to reasonably configure and manage the router becomes one of the important tasks of the Network Manager. This topic describes how to configure a cisco router fro
