Restrictions and precautions of the AR router used as the WLAN AC

19

The restrictions and precautions of the AR router used as the WLAN AC are as follows:
Precautions for parameter settings:
1. In tunnel forwarding mode, the mVLAN and service VLAN must be different.
2. The device used as the AC only supports direct forwarding of service packets. It does not support tunnel forwarding.

License support:
The WLAN AC function is used with a license and is unavailable by default. To use the AC function, apply for and purchase the following license from the agent according to the device model:
1. AR150&160&200 series routers: AR150&160&200 value-added service package for data services and AR150&160&200 wireless controller license
2. AR1200 series routers: AR1200 value-added service package for data services and AR1200 wireless controller license
3. AR2200 series routers: AR2200 value-added service package for data services and AR2200 wireless controller license
4. AR3200 series routers: AR3200 value-added service package for data services and AR3200 wireless controller license
To use WLAN-AC functions, you must load both value-added service package for data services and wireless controller license. A license is used according to the value-added service package loaded on the device; therefore, load a value-added service package before loading the corresponding license.

The mapping between the AC and AP is as follows: Read the product documentation of the required version. Huawei APs must be used.

Restrictions and precautions for using OSPF
Restrictions and precautions for using OSPF are as follows: To establish an OSPF neighboring relationship, devices need to exchange DD packets. DD packets are OSPF unicast packets. By default, OSPF unicast packets are not forwarded under the control of security policies. Therefore, you need to configure a security policy on the FW to permit the OSPF packets between the Local zone and the security zone where the neighboring device resides. Otherwise, the OSPF neighboring relationship fails to be established. Or you can run the undo firewall packet-filter basic-protocol enable command to disable the function of security policy control over OSPF unicast packets. After that, the firewall directly forwards OSPF unicast packets even if a security policy whose action is deny is configured.

What precautions should be taken for using AR routers
Take the following precautions when using AR routers: 1. Routers are powered by high-voltage power sources. High voltage may cause body injuries or even death. Do not open the chassis unless instructed by professionals. 2. Ground the routers properly to protect the routers from lightning. 3. A router has many ESD-sensitive components. Before touching a router, a board or an Application Specific Integrated Circuit (ASIC) chip, wear an ESD wrist strap and connect one end of the wrist strap to the ground. This prevents the ESD-sensitive components from being damaged by the static electricity generated by the human body. 4. AR routers support various WAN interfaces, including GE, FE, ADSL2+, G.SHDSL, FXS, FXO, ISDN, E1/T1, and SA/AS interfaces. The interface connectors are similar. Before connecting cables to WAN interfaces, read the instructions on the panel carefully to ensure that correct cables are connected to the interfaces. NOTE: For more information about use of AR routers, see the product description.

AP types supported by AR routers
You can run the display ap-type all command to check all Fit AP types supported by the AR router by default. By default, AR routers support Huawei Fit APs. The example is as follows: AR V200R008 version:display ap-type all -------------------------------------------------------------------------------- ID Type -------------------------------------------------------------------------------- 17 AP6010SN-GN 19 AP6010DN-AGN 21 AP6310SN-GN 23 AP6510DN-AGN 25 AP6610DN-AGN 27 AP7110SN-GN 28 AP7110DN-AGN 29 AP5010SN-GN 30 AP5010DN-AGN 31 AP3010DN-AGN 33 AP6510DN-AGN-US 34 AP6610DN-AGN-US 35 AP5030DN 36 AP5130DN 37 AP7030DE 38 AP2010DN 39 AP8130DN 40 AP8030DN 42 AP9330DN 43 AP4030DN 44 AP4130DN 45 AP3030DN 46 AP2030DN 47 AP9131DN 48 AP3010DN-V2 -------------------------------------------------------------------------------- Total: 25 AR V200R009 version:display ap-type all -------------------------------------------------------------------------------- ID Type -------------------------------------------------------------------------------- 17 AP6010SN-GN 19 AP6010DN-AGN 21 AP6310SN-GN 23 AP6510DN-AGN 25 AP6610DN-AGN 27 AP7110SN-GN 28 AP7110DN-AGN 29 AP5010SN-GN 30 AP5010DN-AGN 31 AP3010DN-AGN 33 AP6510DN-AGN-US 34 AP6610DN-AGN-US 35 AP5030DN 36 AP5130DN 37 AP7030DE 38 AP2010DN 39 AP8130DN 40 AP8030DN 42 AP9330DN 43 AP4030DN 44 AP4130DN 45 AP3030DN 46 AP2030DN 47 AP9131DN 49 AP5030DN-S 50 AP3010DN-V2 51 AP4030DN-E 68 AP1010SN 69 AP2050DN 70 AP2050DN-E 71 AP8130DN-W 73 AP2050DN-S 75 AP4050DN 76 AP4051DN 77 AP4151DN 78 AP4050DN-S 79 AP4051DN-S 80 AP8050DN 81 AP8150DN 82 AP8050DN-S -------------------------------------------------------------------------------- Total: 40
