Managing a large number of APs is both time consuming and costly. The fit AP+AC network architecture enables an AC to establish Control And Provisioning of Wireless Access Points (CAPWAP) tunnels with a large number of APs for centralized AP management and maintenance.

CAPWAP tunnel

CAPWAP defines how an AP communicates with an AC. It provides a generic encapsulation and transport mechanism between AP and AC. CAPWAP uses UDP and supports both IPv4 and IPv6.

As shown in Figure 1, an AC and an AP establish a data tunnel to forward data packets and a control tunnel to forward control packets.

Figure 1 CAPWAP tunnel

AC discovery

After starting up with zero configurations, an AP automatically creates VLAN-interface 1 and enables the DHCP client, DHCPv6 client, and DNS features on the interface. Then it obtains its own IP address from the DHCP server and discovers ACs by using the following methods:

· Static IP address:

If AC IP addresses have been manually configured for the AP, the AP sends a unicast discovery request to each AC IP address to discover ACs.

· DHCP options:

a. The AP obtains AC IPv4 addresses from Option 138, Option 43, and IPv6 addresses from Option 52 sent from the DHCP server. It uses these addresses in descending order.

b. The AP sends a unicast discovery request to each received AC address to discover ACs.

For more information about DHCP options, see Layer 3—IP Services Configuration Guide.

· DNS:

a. The AP obtains the domain name suffix from the DHCP server.

b. The AP adds the suffix to the host name.

c. The DNS server translates the domain name into IP addresses.

d. The AP sends a unicast discovery request to each IP address to discover ACs.

For more information about DNS, see Layer 3—IP Services Configuration Guide.

· Broadcast:

The AP broadcasts discovery requests to IP address 255.255.255.255 to discover ACs.

· IPv4 multicast:

The AP sends multicast discovery requests to IPv4 address 224.0.1.140 to discover ACs.

· IPv6 multicast:

The AP sends multicast discovery requests to IPv6 address FF0E::18C to discover ACs.

The methods of static IP address, DHCPv4 options, broadcast, IPv4 multicast, IPv4 DNS, IPv6 multicast, DHCPv6 option, and IPv6 DNS are used in descending order.

The AP does not stop AC discovery until it establishes a CAPWAP tunnel with one of the discovered ACs.

CAPWAP tunnel establishment

Figure 2 Establishing a CAPWAP tunnel

As shown in Figure 2, the AP and an AC establish a CAPWAP tunnel by using the following procedure:

1. The AP sends a discovery request to each AC to discover ACs.

2. Upon receiving the discovery request, an AC determines whether to send a discovery response by performing the following steps:

a. Identifies whether the discovery request is a unicast packet.

- Unicast packet—The AC proceeds to step b.

- Broadcast or multicast packet—The AC proceeds to step b if it is disabled with the feature of responding to only unicast discovery requests. If this feature is enabled, the AC does not send a discovery response.

b. Identifies whether it has manual AP configuration for the AP model specified in the discovery request.

- If manual AP configuration exists, the AC sends a discovery response to the AP. The discovery response contains information about whether the AC has the manual configuration for the AP, the AP connection priority, and the AC's load status.

- If no manual AP configuration exists, the AC proceeds to step c.

c. Identifies whether auto AP is enabled.

- If auto AP is enabled, the AC sends a discovery response to the AP. The discovery response contains the enabling status of auto AP, AP connection priority, and AC's load information.

- If auto AP is disabled, the AP does not send a discovery response.

3. Upon receiving the discovery responses, the AP selects the optimal AC in descending order.

¡ AC that saves information about the AP.

¡ AC where the auto AP feature is enabled.

¡ AC with higher AP connection priority.

¡ AC with the lighter load.

4. The AP sends a join request to the optimal AC.

5. After receiving the join request, the AC examines information in the request to determine whether to provide access services to the AP and sends a join response.

6. After receiving the join response, the AP examines the result code in the response:

¡ If the result code represents failure, the AP does not establish a CAPWAP tunnel with the AC.

¡ If the result code represents success, the AP establishes a CAPWAP tunnel with the AC.

AC rediscovery

An AC enabled with AC rediscovery will add the CAPWAP Control IP Address message element to the discovery responses sent to APs. Upon receiving such a discovery response, an AP establishes a CAPWAP tunnel by following this procedure:

1. Examines whether a discovery request has been sent to the IP address specified in the CAPWAP Control IP Address message element.

2. Performs either of the following operations:

¡ Sends a join request to the specified IP address representing the optimal AC for CAPWAP establishment if a discovery request has been sent.

¡ Sends a discovery request to each specified IP address to initiate a new AC discovery process if a discovery request has not been sent.

An AC disabled with AC rediscovery does not add the CAPWAP Control IP Address message element in discovery responses sent to APs. APs that receive the discovery responses will send join requests to the source IP address of the discovery responses to establish CAPWAP tunnels with the AC.

AP configuration methods

You can configure APs by using either of the following methods:

· Configure APs one by one in AP view.

· Assign APs to an AP group and configure the AP group in AP group view.

· Configure all APs in global configuration view.

For an AP, the priorities of the configuration in AP view, AP group view, and global configuration view are in descending order.

APDB

The Access Point Information Database (APDB) on an AC stores the following AP information:

· AP models.

· Hardware version and software version mappings.

· Information about radios supported by AP models.

¡ Number of radios.

¡ Radio type.

¡ Valid region code.

¡ Valid antenna type.

¡ Maximum transmission power.

The AC can establish a CAPWAP tunnel with an AP only when the APDB contains the corresponding AP model information.

You can use the system script and user scripts to manage data in the APDB. The system script is released with the AC software version, and it is automatically loaded each time the AC starts. If you need to add new AP models, upgrade the AC software version (see Fundamentals Configuration Guide) or create a user script and load it on the AC (see "Loading an APDB user script").

Upgrading APs' software

Overview

Software upgrade for an AP proceeds as follows:

1. The AP reports the software version and AP model information to the AC.

2. The AC examines the received AP software version.

¡ If a match is found, the AC establishes a CAPWAP tunnel with the AP.

¡ If no match is found, the AC sends a message that notifies the AP of the AP software version inconsistency.

3. Upon receiving the inconsistency message, the AP requests a software version from the AC.

4. The AC assigns the software version to the AP after receiving the request.

5. The AP upgrades the software version, and restarts to establish a CAPWAP tunnel with the AC.

Configuring software upgrade

The AC examines the AP software version while establishing the CAPWAP tunnel only when software upgrade is enabled. If this feature is disabled, the AC does not examine the software version of the AP and directly establishes a CAPWAP tunnel with the AP.

Configuring software upgrade in AP view

Step	Command	Remarks

Configuring the mapping between a software version and a hardware version of an AP model

CAUTION:

To avoid CAPWAP tunnel establishment failure, use this feature under the guidance of H3C Support.

Perform this task to configure the mapping between a software version and a hardware version of an AP model for software upgrade.

Perform this task only when the AP software version for an AP model stored in the APDB is inconsistent with the software version you expect for the AP model. To display the AP software version for each AP model in the APDB, use the display wlan ap-model command.

For example, the APDB has a hardware version and software version mapping entry (hardware version Ver.C and software version E2108) for AP model WA4320i-CAN. If you expect this AP to use software version E2105 when it comes online, perform the following steps:

1. Configure the mapping between software version E2105 and hardware version Ver.C of AP model WA4320i-ACN.

2. Save the AP image file of software version E2105 to the AC's local folder.

3. Configure the AC to prefer the AP image file stored in the local folder for software version assignment.

To configure the mapping between a software version and a hardware version of an AP model:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Configure the mapping between a software version and a hardware version of an AP model.	wlan apdb model-name hardware-version software-version	By default, the software version for a hardware version of an AP model is the software version that is stored in APDB user scripts.

Specifying the preferred location for the AC to obtain an AP image file

The AC assigns an AP image file to an AP if the AP requests a software version during CAPWAP tunnel establishment. You can specify the preferred location as the AC's RAM or local folder for the AC to obtain an AP image file. If the AC cannot obtain an AP image file from the preferred location, it obtains an AP image file from the other location. If no AP image file exists, the AC fails to obtain an image file and cannot assign a software version to the AP.

Configuration restrictions and guidelines

When you specify the preferred image location for the AC to obtain an AP image file, follow these restrictions and guidelines:

· The AC can assign only .ipe AP image files to APs.

· If you specify the local folder, make sure the AC uses a CF card as the default file system and the AP image file is stored in the root directory of the file system on the AC.

Configuration procedure

To specify the preferred location for the AC to obtain an AP image file:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Specify the preferred location for the AC to obtain an AP image file.	wlan image-load filepath { local \| ram }	By default, the AC prefers the AP image file stored in the RAM when assigning a software version to an AP.

Configuring VLANs for APs

NOTE:

Support for this feature depends on the AP model.

Perform this task to enable the AC to assign VLAN settings to APs for packet forwarding and isolation. For example, when you enable an AP to forward client data traffic, you need to configure ports of the AP to allow client traffic from different VLANs.

For information about VLANs, see Layer 2—LAN Switching Configuration Guide. For information about client data traffic forwarder configuration, see "Configuring WLAN access."

Setting the control tunnel keepalive time for an AP

An AP sends echo requests to the AC at the specified echo interval to identify whether the CAPWAP control tunnel is operating correctly. The AC responds by sending echo responses. If the AP does not receive any echo responses within the keepalive time, the AP terminates the connection. If the AC does not receive any echo requests within the keepalive time, the AC terminates the connection. The keepalive time is the echo interval multiplied by the maximum number of echo request transmission attempts.

Setting the TCP MSS for CAPWAP tunnels

About setting the TCP MSS

Perform this task to set the value of the Maximum Segment Size (MSS) option in SYN packets transmitted over a CAPWAP tunnel.

The MSS option informs the receiver of the largest segment that the sender can accept. Each end announces its MSS during TCP connection establishment. If the size of a TCP segment is smaller than or equal to the MSS of the receiver, TCP sends the TCP segment without fragmentation. If not, TCP fragments the segment based on the receiver's MSS.

Configuring the default input power level

NOTE:

Support for this feature depends on the device model.

Configure the default input power level for an AP in case the AP cannot obtain its input power level at startup.

Input power level overview

An AP automatically performs power supply mode detection to obtain its input power level at startup. If the AP fails to obtain the input power level, it operates at the low power level before associating with an AC. After the association, it operates at the configured default input power level.

An AP can be powered through a power adapter or through its PoE or PoE+ ports. The following table shows the relationship between the AP's power supply mode and input power level:

Power supply mode	Input power level
· Power adapter. · Multiple PoE+ ports. · Combination of PoE and PoE+ ports.	High
· Single PoE+ port · Multiple PoE ports	Middle
Single PoE port	Low

An AP's support for MIMO modes and USB interfaces varies by input power level, as shown in Table 1.

Table 1 AP's support for MIMO modes and USB interfaces

Input power level	Supported MIMO modes	Whether USB interfaces can be enabled
High	1×1, 2×2, 3×3, and 4×4.	Yes.
Middle	1×1, 2×2, 3×3, and 4×4.	Yes when the MIMO mode is 1×1 or 2×2.
Low	1×1.	No.

Configuration restrictions and guidelines

When you configure the default input power level for an AP, make sure the setting matches its power mode. An excessively low input power level prevents the AP from operating correctly. An excessively high input power level causes overload of the AP in case of power shortage.

Changing the interface type to GigabitEthernet

About interface type changing

For some AP models, you can change the interface type from IoT or WTU to GigabitEthernet as required. GigabitEthernet interfaces connect APs to terminal devices such as PC, WTU ports connect APs to WTUs, and IoT interfaces connect APs to IoT modules.

NOTE:

Support for WTU ports and IoT interfaces depends on the AP model.

Configuration restrictions and guidelines

This feature takes effect only on interfaces that support interface type switchover between GigabitEthernet and IoT or WTU.

If you specify the GigabitEthernet interface type for an interface, the default interface type settings will be restored for all the other interfaces on the same AP that support interface type switchover. For example, on a UAP 300, interface 3 and interface 4 support interface type switchover. If you set the interface type of both interfaces to GigabitEthernet and then set the interface type of interface 4 to GigabitEthernet, interface 3 will become an IoT interface.

Configuring an AP group

This feature enables you to configure multiple APs in a batch to reduce configuration workload.

APs in an AP group use the configuration of the group. By default, all APs belong to the default AP group default-group. The default AP group cannot be created or deleted.

You can configure AP grouping rules by AP names, serial IDs, MAC addresses, and IP addresses to add APs to the specified AP group. Priorities of these grouping rules are in descending order. If an AP does not match any grouping rules, it is added to the default AP group.

Configuration restrictions and guidelines

When you configure an AP group, follow these restrictions and guidelines:

· An AP can be added to only one AP group.

· You cannot delete an AP group that contains an AP.

· You cannot create grouping rules for the default AP group.

· You cannot create the same grouping rule for different AP groups. If you do so, the most recent configuration takes effect.

· The configuration priorities for an AP in AP view, AP group view, and global configuration view are in descending order. If no settings are configured in one view, the settings in the view with a lower priority are used. If no settings are configured in any one of the three views, the AP uses the default configuration in the view that has the lowest priority.

· AP grouping rules by IPv4 or IPv6 addresses for an AP group or for different AP groups cannot overlap with each other.

· An AP group supports a maximum of 32 AP grouping rules by IPv4 or IPv6 addresses.

9. (Optional.) Create an AP regrouping rule.	wlan re-group { ap ap-name \| ap-group old-group-name \| mac-address mac-address \| serial-id serial-id } group-name	N/A

Preprovisioning APs

AP preprovisioning allows you to configure network settings for fit APs on an AC. The AC automatically assigns these settings to the fit APs in run state through CAPWAP tunnels in a batch. This reduces the work load in large WLAN networks.

You must save these settings in configuration file wlan_ap_prvs.xml for an AP.

This feature takes effect only on master ACs.

You can configure network settings in AP provision view or AP group provision view. Settings in AP provision view have a higher priority.

If you modify the preprovisioned settings of an AP, resave the settings in the preprovisioned configuration file.

The save wlan ap-provision command has the same effect as the reset wlan ap provision command if no preprovisioned settings exist.

Preprovisioned settings configured in provision view take effect immediately when you execute the save wlan ap provision command.

Cancellations of preprovisioned settings in provision view do not take effect when you execute the save wlan ap provision command. For the cancellations to take effect on an AP, restart the AP.

For the reset wlan ap provision command to take effect on an AP, restart the AP after execution.

Assigning preprovisioned settings to APs

Perform this task to enable the AC to assign preprovisioned settings to an AP with which the AC has established a CAPWAP tunnel. The preprovisioned settings will be saved to configuration file wlan_ap_prvs.xml on the AP, and the settings will overwrite the network settings saved in the configuration file.

You can use either of the following methods to assign preprovisioned settings to an AP:

· Manual configuration—You save the preprovisioned settings to configuration file wlan_ap_prvs.xml on the AP after it comes online.

Modifying the AC address configuration in the configuration file of the AP will trigger a new optimal AC selection process. Then the AP will terminate the original CAPWAP tunnel and establish a CAPWAP tunnel with the new AC.

· Auto assignment of preprovisioned settings—The preprovisioned settings are assigned to an AP when it is coming online. The AP will establish a CAPWAP tunnel with the AC specified in the preprovisioned settings. For information about optimal AC selection , see "CAPWAP tunnel establishment."

Saving the network settings to the configuration file on an AP

Configuring auto loading of preprovisioned settings

Auto loading of preprovisioned settings ensures successful CAPWAP tunnel establishment between AP and AC. An AP uses the following procedure to discover an AC when you enable this feature:

1. Uses the preprovisioned settings to discover an AC that has the AP's manual or auto AP configuration.

2. Reboots and uses other methods to discover ACs if AC discovery fails.

3. Reboots and uses the preprovisioned settings again to discover ACs if the AP still fails to discover the target AC.

This AC discovery process will be repeated until the AP discovers the target AC to establish a CAPWAP tunnel.

Loading an APDB user script

Perform this task to add new AP models to the APDB without upgrading AC software.

Configuration restrictions and guidelines

When you load an APDB user script, follow these restrictions and guidelines:

· Make sure the user script is valid. Invalid scripts can cause loading failure.

· The AP models in the user script must be different from the AP models in the system script.

· If you load multiple user scripts on the AC, the most recently loaded user script overwrites the old user scripts.

· If you rename the user script in the file system, reload the user script to prevent AP model configuration in the user script from being lost after an AC reboot.

· If you replace the user script with a new user script in the file system, reload the new user script. If the new user script does not include AP model information saved in the replaced user script, the AP model information will be lost after an AC reboot.

· If you delete a user script in the file system, the AP model configuration in the user script will be lost after an AC reboot.

If an old user script already exists, follow these restrictions and guidelines when you load an APDB user script:

· If a manual AP or an online auto AP whose model is listed in the old user script exists ,you can load a new user script only when you delete the corresponding AP model information on the AC.

· If APs of an AP model listed in the old user script have been added to an AP group, you can load a new user script only when you remove the APs from the AP group.

· If the old user script includes an AP model whose software version was already configured, you can load a new user script only when you use the wlan apdb command to restore the original software version.

CAPWAP tunnel establishment through DNS configuration example

Network requirements

As shown in Figure 5, configure the AP to obtain the IP address of the AC through DNS to establish a CAPWAP tunnel with the AC.

Figure 5 Network diagram

Configuration procedures

1. Configure the DHCP server:

# Enable the DHCP service, configure DHCP address pool 1, and set the domain name suffix of the AC to abc.

<DHCP server> system-view

[DHCP server] dhcp enable

[DHCP server] dhcp server ip-pool 1

[DHCP server-dhcp-pool-1] network 1.1.1.0 mask 255.255.255.0

[DHCP server-dhcp-pool-1] domain-name abc

[DHCP server-dhcp-pool-1] dns-list 1.1.1.4

[DHCP server-dhcp-pool-1] gateway-list 1.1.1.2

[DHCP server-dhcp-pool-1] quit

[DHCP server] quit

2. Configure a mapping between domain name h3c.abc and IP address 2.1.1.1/24. For more information, see Layer 3—IP Services Configuration Guide. (Details not shown.)

3. Configure the AC:

# Set the IP address of VLAN-interface 1 to 2.1.1.1/24.

<AC> system-view

[AC] interface vlan-interface 1

[AC-Vlan-interface1] ip address 2.1.1.1 24

[AC-Vlan-interface1] quit

# Configure a default route with next hop address 2.1.1.2.

[AC] ip route-static 0.0.0.0 0 2.1.1.2

# Create AP ap1 and specify its model and serial ID.

[AC] wlan ap ap1 model WA4320i-ACN

[AC-wlan-ap-ap1] serial-id 210235A1BSC123000050

# Start up the AP.

[AC-wlan-ap-ap1] quit

The AP performs the following operations:

¡ Obtains its IP address 1.1.1.1, the domain name suffix of the AC, and the IP address of the DNS server from the DHCP server.

¡ Adds the domain name suffix to the hostname.

¡ Informs the DNS client to translate the domain name into an IP address.

¡ Uses the IP address of the AC to establish a CAPWAP tunnel with the AC.
