communicate with each other directly, and mutual access between hosts in different VLANs must be forwarded through the routing device. Broadcast packets can only be broadcast within this VLAN and cannot be transferred to other VLANs.· The Port VLAN is one way to implement VLANs, and it uses the port of the switch to partition the

I. Features of VLAN VLAN has the following features:Segmented, which can be divided into different network segments by department, function, and project;Flexibility: users who make up a VLAN do not need to consider the physical location of the thing. The same VLAN can also span multiple switches;Security: by separatin

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

configuration, which has been written for a long time,2950 The basic configuration of the switch, currently we are commonly used to configure the VLAN, the other is easy to manage, configure the IP address and allow Telnet login.

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 t
