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

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

Cisco switch by default. But it can be implemented with only one command, namely: 3550 # terminal monitor. In order to experience the actual effect, we can open two DOS windows on our PC and log on to the same Cisco switch through TELNET. One is used for monitoring, and the other is used to perform specific operations
