cisco l3 switch

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 of creating a static VLAN is to forcibly allocate the port to a VLAN. That is, we first create a VLAN on The VTP (VLAN Trunking Protoco

Cisco L3 switch Policy Routing for network access and Traffic DistributionI. Description of the solution environment 1. There are two groups of Group1 and Group2 in the environment, respectively, to access the Internet from two different network outlets. 2. The core network is a Cisco 3560G layer-3

Configuration of a layer-3 Cisco switch 1. Start a route on a layer-3 switch. Otherwise, layer-3 switch does not have the routing function switch (config) # ip routing2. Configure the VLAN ip address switch (config) # interface vl

. L2 forwarding: the L2 forwarding feature of a l3 Ethernet switch conforms to the 802.1D bridge protocol standard. Layer-3 Ethernet switch layer-2 forwarding involves two key threads: address learning thread and message forwarding thread. The Learning thread is as follows:◆ The layer-3 Ethernet switch receives all dat

same network segment can be observed. Where routed port uses the physical interface of the MAC address, SVI uses MAC address device MAC address +1. 2, under the SVI configuration e0/0 still work l2,routed port under the e0/0 completely in L3 work. A reply to this issue on the Cisco Web site is referenced below . There is a difference the way both the connection works. Although they would have the same p

management switching equipment.Finally, it is worth pointing out that some people to some extent there are some vague concepts, that the so-called fourth-layer switch is actually added on the third layer of the switch with the ability to identify the fourth protocol port, only on the third layer of the switch to add some value-added software, and therefore not w

Recently, the IOT platform has launched an intelligent three-layer Ethernet switch product TS3026E for Broadband Metropolitan Area Network Access and CEN workgroup access. This product is developed based on the industry's mature Ethernet ASIC switching technology and self-developed SPROS operating system. It provides sound line rate traffic switching, QOS Assurance, VLAN control, and other mechanisms, with complete business control and user management

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 present. This article is going to introduce one of
