cisco native vlan

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

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, configure

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

Through the previous experiment we learned that by configuring VLANs, the terminals under different VLANs could not communicate with each other, but if you wanted to communicate between different VLANs, you would need to configure inter-VLAN routingLayer three switches have the capability of the network layer and can be forwarded via the routing functionNetwork environment1 set the IP address and gateway of the terminal (192.168.1.1 and 192.168.2.1, r

Each UCS rack server is equipped with a VIF interface card that provides two Gigabit Ethernet interfaces. using Cisco Network virtualization technology, it provides both management network interfaces and operating system network interfaces.

Branch switches.The Cisco switch can support any media as a trunk line. To achieve relay, you can use its unique isl tag.

What is the difference between an acl and a vacl between a cisco vlan, its implementation method is to apply the ACL directly to the virtual port of the VLAN, which is the same as the ACL implementation method applied to the physical port. The VLAN access control (VACL), also known as the
