Q & A set for configuring VLAN Switches

How do I configure a VLAN switch in a WLAN connection? The following are common problems of netizens. There are no other solutions. The following articles will provide you with corresponding solutions.

Q: How do I configure a VLAN switch in a WLAN connection? A: Virtual lan vlan) is used to logically divide a LAN into several independent broadcast domains and independent physical topology extensions. The LAN divided into logical fragments can be any type of LAN, including Ethernet and Wi-Fi.

The endpoint-based VLAN relies on the vswitch or AP to configure the VLAN switch membership. For example, Ports 1 to 8 of A vswitch constitute VLAN #1, and ports 9 to 16 constitute VLAN #2. Each site in VLAN #1 receives the same LAN broadcast, but the site in VLAN #2 does not receive the broadcast.

Similarly, you can set a Wireless AP to transfer traffic in VLAN #1 and a named network SSID), or in VLAN #2 and a name for a network SSID. This technology is generally used to distinguish between customer wireless traffic and other private wireless traffic of wired networks.

802.1Q uses the label vlan id in the LAN architecture) to distinguish traffic. VLAN tags enable devices that support 2.1Q, such as switches, APS, routers, and firewalls, to enhance VLAN differentiation through the entire path of data packets. As described above, you can configure a Wireless AP to provide VLAN tags to a specific SSID architecture.

Alternatively, Wireless AP can assign VLAN tags for each site to receive during 802.1X authentication. 802.1X authentication is required by the RADIUS server of RFC 3580. This technology can put individual users in the correct VLAN Based on the authentication identity rather than the SSID they connect.

VLAN can be extended to the entire company's network, from the branch, through the WAN, to the headquarters. A VLAN label does not pass through the entire path, because VLAN only supports LAN. However, you can configure routers and firewalls to map VLAN switch tags to network subinterfaces.

For example, when traffic in VLAN #1 is in the Internet, it may be directed to VPN Channel. The traffic in VLAN #2 flows through VPN channel B. The traffic in the two VPN channels is likely to spread from the same WAN connection. In other words, the VPN channel can separate the traffic in Layer 3 from the IP network, just like configuring a VLAN switch to separate the traffic in Layer 2 from the LAN.
