## AWC-SC (AWC-Smart Connect)

AWC-SC (AWC-Smart Connect) is our original solution that streamlines the introduction and expansion of wireless networks through autonomous wireless connection between APs.
In a wireless network using AWC-SC (a Smart Connect network), APs are connected wirelessly like in a WDS (wireless distribution system). This means there is no need to connect to a wired LAN, except for the root AP at the top level.
In WDS, when connecting a satellite AP by wireless, it is necessary to preconfigure the AP in advance. However, with AWC-SC, if you have a DHCP server that can communicate with the subnet where the satellite AP will be connected, and the MAC address of the satellite AP is registered in the AWC plug-in, a factory default AP can join the Smart Connect network by simply unboxing, installing, and powering on the AP.
In a Smart Connect network, the wireless connection path between APs changes dynamically according to the surrounding conditions. This means communication is performed on the optimal path, while also providing a redundant communication path.
◼ Conventional Wireless Network
◼ Smart Connect Network

### Roles of Wireless APs

In AWC-SC, the roles of wireless APs are broadly classified as follows:

- Root AP
  A wireless AP located at the most upstream position of a Smart Connect network.
  It has a connection to the wired network, and bridges packets between the wirelessly-connected Satellite APs and the wired network.
  It has the same role as the Root AP in WDS, but in AWC-SC there can be multiple Root APs as well as Satellite APs (Connector APs and Terminator APs).
- Satellite AP
  A downstream wireless AP that is only connected wirelessly to other APs in a Smart Connect network.
  The wireless connection paths between APs are automatically constructed and changed according to the surrounding conditions.
  - Connector AP
    A wireless AP located in the middle of the AWC-SC's multi-tier wireless connection.
    It bridges packets from the Root AP to the Terminator AP and clients, and from the Terminator AP and clients to the Root AP.
    Bridging by Connector AP is supported only once (2 hops from Root AP-Connector AP-Terminator AP.)
  - Terminator AP
    A wireless AP located on the edge of the AWC's multi-tier wireless connection.
    It bridges packets between wireless clients and the upstream devices (Root APs and Connector APs).

In an actual environment, the signal sensitivity also changes depending on the movement of people and objects between wireless APs. If communication is poor, the satellite APs attempt to switch the upstream connection destination.
◼ In case of TQ5403, TQ5403e and TQm5403
In a Smart Connect network consisting of TQ5403, TQ5403e and TQm5403, up to four wireless APs can be connected directly downstream for both root and connector APs.
This means that at most, up to 4 Connector APs and 16 Terminator APs can be connected to a single Root AP.
It is recommended that when designing the network, you allow some margin for the number of Root APs compared to the number of Satellite APs.
If there are not enough Root APs, the path may not be optimal depending on the order in which the satellite APs are installed.
For example, if the communication state between the Root AP and the Satellite AP (AP1) is stable, but the radio wave is very weak, AP1 is unable to be a Connector AP and accept a Smart Connect connection request from another wireless AP (AP2).
Here, a new wireless AP (AP3) has been installed between the Root AP and AP1.
Assuming the Root AP has the capacity to accept Satellites, the Root AP and AP3 will establish a Smart Connect link with a strong radio wave. Next, by optimizing the connection route, AP3 will bridge between AP1 and AP2 to the Root AP, acting as a Connector AP.
However, if the Root AP already has connections with four Satellite APs, and the Root AP and AP1 are still connected with a weak but stable signal, AP3 cannot join the Smart Connect network.
In this case, temporarily stop AP1 that is connected with a weak signal. This allows the Root AP to have AP3 joined under it. Performing as a Connector AP, AP3 can then join AP2 to the Smart Connect network, as well as AP1 after rebooting it.
◼ In case of TQ6602 GEN2 and 6702 GEN2
In the case of a Smart Connect network consisting of TQ6602 GEN2 and TQ6702 GEN2, up to 21 satellite APs can be connected to one root AP, regardless of whether it is a connector AP or a terminator AP.
Supports relaying up to two hops (Root AP - Connector AP - Terminator AP). It is not possible to relay from a connector AP to a further different connector AP.

> Note

> > When installing Satellite APs, pay attention to the number and distance of adjacent wireless APs.
> > If a large number of Satellite APs are arranged so that the distance between wireless APs becomes too short, the throughput of the entire Smart Connect network may be significantly reduced.

### Configured VAPs

AWC-SC uses two VAPs as an alternative to wired networks between wireless APs.

- SC Management VAP
  This is a VAP used to communicate between wireless APs in a wireless network established with AWC-SC.
  It operates by overwriting VAP1 of the AP Profile in the radio band selected as "Frequency" in the SC Profile.
  The SSID can be set arbitrarily, but will not be broadcast.
  The encryption method is fixed to "WPA2 Personal", and the security key (WPA2-PSK) can be set arbitrarily.
- SC Provisioning VAP
  This is a VAP that allows factory default APs to find a Root AP and join to the Smart Connect network.
  It operates by overwriting VAP2 of the AP Profile in the radio band selected as "Frequency" in the SC Profile.
  The SSID is fixed to "sc-initial-provisioning" and will not be broadcast.
  The encryption method is fixed to "WPA2 Personal". The Security Key (WPA2-PSK) is hidden and can not be changed.

> Note

> > In the radio band used by AWC-SC, the other VAPs will be disabled automatically.

## Required Licenses

The following licenses are required to use AWC-SC functions on AWC Plug-in.

- Vista Manager EX License
- Wireless LAN Controller License (10 APs)
- Wireless Smart Connect License (10 APs)

  > Note

  > > The Wireless Smart Connect License may be included within the Wireless Channel Blanket License (hereafter referred to as the "Wireless CB+SC Integrated License").
  > > A Wireless CB+SC Integrated License has the suffix "-2022" added to the product name on the license certificate. When the concerned license is applied to Vista Manager EX, the license name displayed in the "Licenses" section of the "System Management" screen will show "AWC Channel Blanket" and "AWC Smart Connect" as separate functions, just as in the past.
  > > Please note that TQm5403 will no longer be supported as a Smart Connect satellite when using the Wireless CB+SC Integrated License.

The required unit number of Wireless Smart Connect licenses varies depending on the number of wireless APs belonging to the AWC-SC. A single Wireless Smart Connect license lets you operate up to 10 APs in AWC-SC. Adding more licenses increases the number of APs that can be operated in Smart Connect.
In addition, when using AWC-CB together with AWC-SC, you may need both Wireless Smart Connect licenses and Wireless Channel Blanket licenses that satisfy the number of the APs that are operated in both AWC-SC and AWC-CB.

Table 1: Example of required licenses
| Non-SC (Conventional) | Smart Connect | Total | Numbers of Licenses
--- | --- | --- | --- | ---
Multi-channel | AWC-CB | Multi-channel | AWC-CB
Number of APs | 16 | 16 | 16 | 16 | 64 |
Vista Manager EX License | 1 | 1 | 1
Wireless LAN Controller License (10 APs) | 16 | 16 | 16 | 16 | 64 | 7 units (Max 70 APs)

> Note

> > The number of APs shown above indicates the maximum number that can be connected and does not guarantee communication quality.
> > To ensure communication quality, design by taking into account the usage environment and bandwidth used.

## Smart Connect Configuration Process

To build a hybrid wireless system, follow the steps below.

### Configuring Smart Connect on Wired AP

To register the wireless AP to the AWC Plug-in, the MAC and IP Addresses of the AP are needed.
For satellite APs that connect only by wireless communication, please prepare an AC adapter separately, as the UTP cable is unplugged after the setup is complete.

1. Configure an IP address via the AP's web interface.
   Connect the wireless AP to the PC with a cable directly, or via a switch, and set a fixed IP address for the AP from the AP's web interface.

   > Note

   > > The Root AP can also obtain a static registered IP address from the DHCP server.

2. Access the management web interface of the AWC Plug-in.
3. Register the AP on the AP Settings screen.
   Specify the corresponding Management Group, MAC Address, and IP Address of the AP.
4. Next, create the AP Profiles.
   On the AP Profile screen, create an AP Profile that will be used for communication between wireless APs managed by AWC-SC and wireless clients.
   For communication between APs managed by AWC-SC, the SC Profile created in the later steps will be used. In this SC Profile, two dedicated VAPs will be created on the wireless band that AWC-SC uses.
   Different radio bands are used for normal client service communications.
5. Create CB Profile as required.
   Create a channel blanket to apply the CB Profile to, and select the wireless APs that belong to it.
   Refer to Create/Edit/Delete CB Profile and Create Channel Blanket for more details.
   When creating a CB VAP, specify a VAP number for the CB VAP that is different from the wireless band used for Smart Connect, avoiding the VAP number of the VAP used as a multichannel wireless network created in Step 4.
6. Create an SC Profile.
   On the SC Profile screen, create an SC Profile for communication between the APs under the control of AWC-SC.
   Only one SC Profile can be created for each Management Group. If you create multiple Smart Connect networks, Management Groups must be separated for each network.
   Specify the management group to which the SC Profile applies, and the SC management SSID for communication between wireless APs. You can also set the wireless band and channel to use here.
   Refer to Configure SC Profile for more details.
7. Select the wireless APs to be managed on the Smart Connect Network.
   In the AP list of the SC Profile, all APs belonging to the same management group specified as the target of the SC Profile are displayed in a list. Select "Enable" or "Disable" for Smart Connect for each AP.

   > Note

   > > If there are APs that do not support AWC-SC in the same Management Group, set Smart Connect to "Disable". When Smart Connect is set to "Enable" for an AP that does not support AWC-SC, some wireless settings that overlap with the SC Profile, such as the channel used, are ignored.

   Also, select the wireless AP to be set as the "Root AP" that is the bridge with the wired network.
8. Assign the AP Profile to the APs registered in Step 3.
9. Connect the wireless APs to a switch within the management range of the Smart Connect network (in the management group) with UTP cables.
10. Turn on the APs.
    At this point, the wireless AP that you intend to use as a root AP can be powered either by PoE or by a power adapter.
    Wireless APs that you intend to operate as satellite APs should be powered using the power adapters, as you will unplug the UTP cables in a later step.
    In addition to the AP Profile assigned in Step 8, the SC Profile, and the CB Profile if necessary, will be applied to the APs.
    When the configuration is completed, the management status on the AP Settings screen changes to "Managed".
11. If the channel setting is set to "Automatic" in the SC profile, on the AWC Settings screen, check the checkbox for the management group to which the wireless APs belong and click the "Calculate and Apply" button at the top right of the screen.
    By performing and applying the AWC calculation, the channels used in the radio band for the AP in AWC-SC are automatically set to the identical number.
12. Leave the wireless AP that you set as the Root AP in Step 7 connected by UTP cable. Disconnect the UTP cables of the other wireless APs intended to operate as Satellite APs.
    The Satellite APs will communicate with the Connector/Root APs in the upper level via the SC management SSID.

### Configuring Smart Connect Wirelessly

You can add a factory default AP to your Smart Connect network via wireless communication between the APs.
Smart Connect allows you to expand the wireless network without time-intensive processes like cable work.
Since the factory default AP has no IP address assigned, it is necessary to assign an IP address by a DHCP server via the Root AP.

> Note

> > In order to configure and manage a Satellite AP by using OTA (Over The Air), it is necessary that the AP model supports the Smart Connect feature, runs the firmware version shown below, and is in factory default status.
> > - TQ5403, TQ5403e, TQm5403: firmware version 6.0.1-1.1 or later
> > - TQ6602 GEN2, TQ6702 GEN2: firmware version 8.0.3-0.1 or later
> > Additionally, when using OTA to add the satellite AP right after a firmware upgrade, log on to the AP and perform an initialization before adding it under management.
> > Refer to the firmware reference manual of the AP for the initialization procedure.

> Note

> > Do not turn on the wireless AP until instructed to do so.

1. On the DHCP server on the wired network, specify the IP address of the AWC plug-in and the monitoring port number (65437) as DHCP option 43 (vendor specific information).
   This setting is required only once for the DHCP pool.
   The format of the AWC server information passed as an optional setting value is as follows:
   The following setting shows an example in which the IP address of the AWC Plug-in is set to "192.168.1.250":

   Table 2: DHCP option 43 format
   Field name | Field length | Description | Variable / Fixed | Setting Example
   --- | --- | --- | --- | ---
   Content | Hexadecimal value
   Header | 1 octet | Information header to be passed as vendor-specific information. | Fixed | 207 | CF
   Option 1 type | 1 octet | Indicates that the following field is the IP address of the AWC Plug-in. | Fixed | 1 | 01
   Option 1 value | 4 octets | Specify the IPv4 address of the AWC Plug-in. | Variable | 192.168.1.250 | C0A801FA
   Option 2 type | 1 octet | Indicates that the following field is the monitoring port number of the AWC Plug-in. | Fixed | 2 | 02
   Option 2 value | 2 octets | Specify the monitoring port number of the AWC Plug-in. | Fixed | 65437 | FF9D

   As a result, if you are running the DHCP service on an AlliedWare Plus device and you have installed the AWC Plug-in at IP address "192.168.1.250", you will need to add the following settings to the relevant DHCP pool. Here, it is assumed that the DHCP option name to be set is "awcserver" and the DHCP pool name is "pool1".
   `awplus#configure terminal
   awplus(config)#ip dhcp option 43 name awcserver hex
   awplus(config)#ip dhcp pool pool1
   awplus(dhcp-config)#option awcserver cf01c0a801fa02ff9d
   `
2. On the DHCP server, set a static IP address for the MAC address of the Root AP.
3. Register the AP on the AP Settings screen.
   Specify the Management Group and MAC address of the corresponding wireless AP.
   Select "DHCP" for IP Address.
4. Create an AP Profile as required.
5. If necessary, select or create a channel blanket to which the CB Profile is applied, and add the registered AP to it.
   Refer to Create/Edit/Delete CB Profile and Create Channel Blanket for more details.
6. Check that the new wireless APs are displayed correctly on the SC Profile screen.
   In the AP list of the SC Profile, all APs belonging to the same management group specified as the target of the SC Profile are displayed in a list.
   For newly registered APs, Smart Connect is automatically set to "Enable".
   Since the wireless AP is not connected with a UTP cable, it cannot operate as a Root AP that is a bridge to a wired network, so keep the "Root" checkbox unchecked.
7. Assign the AP Profile to the APs registered in Step 3.
   On AP Settings screen, assign the AP Profile. When the AP Profile is assigned, the Management Status of the AP will change to "Searching".
8. Referring to Configuring Smart Connect on Wired AP, add the Root AP under management.
9. Power on the factory default AP that is used as a Satellite AP, using the AC adapter.
   The factory default AP automatically starts the process of joining under AWC-SC management once it has completed booting.
   1. The new wireless AP scans each channel sequentially, searches for the SC initial setting VAP beacon sent by surrounding wireless APs, and tries to connect.
      At this time, on the wireless AP, the WIRELESS LAN LED (2.4GHz, 5GHz 1, and 5GHz 2) corresponding to the wireless band used for the scanning beacon flashes slowly (once per second).

      > Note

      > > The AP will send signals also in the channels in the DFS band (5GHz W53/W56), however, these channels can not be used for Smart Connect.

   2. When a new wireless AP connects to the SC initial setting VAP sent by the wireless AP managed by AWC-SC, the wireless AP managed by AWC-SC assigns a temporary IP address to the new wireless AP.
      At the same time, the MAC address of the new wireless AP is checked against the MAC address list of the candidate wireless APs to be managed. When the AWC Plug-in permits joining, the information of the SC management VAP defined in the SC Profile is sent to the new wireless AP via the APs managed by the AWC-SC, and allows it to connect to the Smart Connect network. After the connection by AWC-SC is established, the new AP obtains the IP address and DHCP option 43 (vendor specific information) from the actual DHCP server, and refers to the DHCP option information to send a request to join the AWC server.
      When a new wireless AP joins, the AWC plug-in associates the registered MAC address with the IP address and transfers the assigned AP, CB, and SC Profiles to the new wireless AP.
      During this time, the WIRELESS LAN LED (2.4GHz, 5GHz 1, or 5GHz 2) corresponding to the wireless band used for communication with the Root AP / Connector AP managed by AWC-SC blinks rapidly (about 4 times per second).
   3. When the transfer of the Profiles is completed, the AP disconnects the wireless connection and applies the settings.
   When the configuration is completed, the management status on the AP Settings screen changes to "Managed".

## Notes

Please note the following points when you use AWC-Smart Connect.

- Radio 1 (2.4GHz band) and Radio 2 (5GHz band W52) can be used for AWC-SC connection. Radio 2 (5GHz band W53) and Radio 3 (5GHz band W56), which are DFS detection target channels, cannot be used.
  The AP Profile and SC Profile have some similar options (such as Channel or Bandwidth of the radio band). The settings on the SC Profile take precedence.
  For setting items that are only found in either AP Profile or SC Profile, they are applied to the wireless AP as they are.
  However, the VAP settings in the AP Profile that overlap with the wireless bands used for Smart Connect are ignored.
  - In the wireless band that is used by Smart Connect, the VAP for SC communication occupies VAP1.
  - When Auto Discovery is enabled, the SSID "sc-initial-provisioning" for connecting the factory default wireless AP to the Smart Connect network occupies VAP2 in the same wireless band. When Auto Discovery is disabled, "sc-initial-provisioning" will not be set for VAP2. In this case, VAP2 will be disabled.
  - On the wireless band that is used by AWC-SC, VAPs other than VAP1 and VAP2 described above are all disabled. Creating a VAP for client service on the wireless band that is used by AWC-SC is not supported.
- If the Selection Type of channel is set to "Auto" in the SC Profile, the wireless channel used by the SC management SSID of the wireless APs belonging to the Smart Connect network must be set to the identical channel by performing and applying the AWC calculation.
  When a wireless AP to which the relevant SC Profile is to be applied to is added to the management for the first time via a wired connection (or when applying the settings), please calculate and apply the AWC function after adding it to the management.
- When using AWC-SC Auto Discovery, it cannot be used in a network configuration where the wireless AP receives packets with the network address 172.31.0.0/24.
  This address range is used only for wireless communication when Auto Discovery is enabled.
  When using AMF on the AlliedWare Plus switch, packets using this network address will not be sent to the AP, so this restriction does not apply.
- Assigning the VLAN ID that is not assigned for client service on the Root AP to a Satellite's client service is not supported.
- The wireless bands used for Smart Connect do not support the use of Neighbor AP Detection together.
- The wireless bands used for Smart Connect do not support the use of dynamic VLANs together. Dynamic VLAN will be automatically disabled, even if enabled.
  In addition, when using Dynamic VLAN in the wireless band used for client communication, dynamic VLAN for the band must be enabled in the AP Profile in advance.
- The combination of the Smart Connect feature and WDS is not supported.
- The combination of the Smart Connect feature and the AMF Guest Device feature is not supported.
- When you use the Smart Connect feature, DHCP Snooping on the switch port that connects the AP is not supported.
- The combination of the Smart Connect feature and Link Aggregation is not supported.
- In AWC-SC, a Satellite AP will automatically select a destination AP to connect to. The connection destination will be changed according to the signal conditions. You cannot set a static connection destination.
- The maximum number of hops for AWC-SC is up to 2. Depending on the radio condition, a Satellite AP may not be able to connect another hop further from Root AP.
- The combination of the Smart Connect feature and the Management VLAN Tag on APs is not supported. Do not set Management VLAN Tag to "Enable".
- Emergency mode can not be used together with AWC-SC.
  In the AP Profiles that apply to APs belonging to the Smart Connect network, do not set "Use Condition" to "Only Emergency Mode" for radio bands that use Smart Connect.
  In addition, do not set any VAP Statuses to "Emergency" in the radio band.
- The TQ6602 GEN2 and TQ6702 GEN2 cannot coexist with the TQ5403/5403e or TQm5403 on the same Smart Connect network.
  If these APs are registered in the same management group, please select the target APs appropriately in the AP list in the SC Profile so that the Smart Connect network is configured only for one of the series.
  If you want to configure several Smart Connect networks with these different series of APs, register each series in a different management group and apply separate SC Profiles.
- On TQ6602 GEN2 and TQ6702 GEN2, mixed usage of AWC-SC or AWC-CB is not supported.
  If you try to apply a configuration with both the SC Profile and CB Profile enabled, the relevant AP will leave the AWC Plug-in's control. In this case, disable either or both the AWC-SC and AWC-CB functions and then re-register the AP.
- When using TQ6602 GEN2/6702 GEN2, if the configuration of the wireless AP is switched from one of cellular VAP (non-CB/SC VAP) only; AWC-CB only or AWC-CB/cellular combination; or AWC-SC/cellular combination; to a different configuration (e.g. cellular VAP only to/from AWC-CB/cellular combination), the wireless AP will restart after the configuration is applied.
