Configuring VLAN of the CX111


The VLAN technology divides a physical LAN into multiple broadcast domains, each of which is called a VLAN. The VLAN technology brings the following benefits:
? Limits broadcast domains. A broadcast domain is limited in a VLAN. This saves bandwidth and improves network processing capabilities.
? Enhances network security. Packets from different VLANs are separately transmitted. Hosts in a VLAN cannot directly communicate with hosts in another VLAN.
? Improves network robustness. A fault in a VLAN does not affect hosts in other VLANs.
? Flexibly sets up virtual groups. With the VLAN technology, hosts in different geographical areas can be grouped together. This facilitates network construction and maintenance.

Configure VLANs of the CX111 by following the instructions provided in the configuration guide:

Default user name and password of the CX11x
The default user name and password of the BMC and GE switching plane of the CX11x are as follows: Default user name: root Default password: Huawei12#$ In some cases (such as serial port login and BIOS login), you only need to enter the password but do not need to enter the user name.

Configure the service VLAN and management VLAN
Configure the service VLAN and management VLAN. 1. Service VLAN - Command output on the AC: [HUAWEI]wlan [HUAWEI-wlan-view]service-set name test [HUAWEI-wlan-service-set-test]service-vlan 100 Multiple service sets have access to different service VLANs. 2. Management VLAN - Configure PVID and untag for the management VLAN on the switch connected to the AP. Allow packets from the management VLAN to pass through. - On Fit APs, no configuration is required for the interfaces connected to the switch. - On Fat APs, the configurations for wired-side interfaces are the same as the configurations for the interfaces on the switch. Note: 1. It is recommended that you configure the service VLAN and management VLAN differently, and do not use VLAN 1 for both VLANs. 2. In normal cases, there is only one management VLAN, but multiple service VLANs can be configured as required. 3. A service set can contain only one service VLAN. 4. In tunnel forwarding, the switch between the AP and AC does not allow packets from service VLANs to pass through, but in direct forwarding, the switch must allow packets to pass through. 5. If the service VLAN or management VLAN is changed, VLAN configurations on the devices along the path must be modified. If the network is newly deployed, you are advised to dial 400-822-9999 to seek assistance from Huawei's presale team to perform the network planning first.
