Example for Configuring Layer 3 Direct Forwarding in Bypass Mode

Service Requirements

Enterprise users can access the network through WLANs, which is the basic requirement of mobile office. Furthermore, users' services are not affected during roaming in the coverage area. A VLAN pool is configured as service VLANs to prevent IP address insufficiency or waste. Furthermore, this measure can reduce the number of users in each VLAN and the size of the broadcast domain.

Networking Requirements

  • AC networking mode: Layer 3 networking in bypass mode
  • DHCP deployment mode:
    • The AC functions as a DHCP server to assign IP addresses to APs.
    • The aggregation switch (SwitchB) functions as a DHCP server to assign IP addresses to STAs.
  • Service data forwarding mode: direct forwarding

Configuration Roadmap

  1. Configure network interworking of the AC, APs, and other network devices.
  2. Configure a VLAN pool for service VLANs.
  3. Configure the APs to go online.
    1. Create an AP group and add APs that require the same configuration to the group for unified configuration.
    2. Configure AC system parameters, including the country code and source interface used by the AC to communicate with the APs.
    3. Configure the AP authentication mode and import the APs offline to allow the APs to go online.
  4. Configure WLAN service parameters for STAs to access the WLAN.

Configuration Notes

  • No ACK mechanism is provided for multicast packet transmission on air interfaces. In addition, wireless links are unstable. To ensure stable transmission of multicast packets, they are usually sent at low rates. If a large number of such multicast packets are sent from the network side, the air interfaces may be congested. You are advised to configure multicast packet suppression to reduce impact of a large number of low-rate multicast packets on the wireless network. Exercise caution when configuring the rate limit; otherwise, the multicast services may be affected.
    • In direct forwarding mode, you are advised to configure multicast packet suppression on switch interfaces connected to APs.
    • In tunnel forwarding mode, you are advised to configure multicast packet suppression in traffic profiles of the AC.
    For details on how to configure traffic suppression, see How Do I Configure Multicast Packet Suppression to Reduce Impact of a Large Number of Low-Rate Multicast Packets on the Wireless Network?.
  • Configure port isolation on the interfaces of the device directly connected to APs. If port isolation is not configured and direct forwarding is used, a large number of unnecessary broadcast packets may be generated in the VLAN, blocking the network and degrading user experience.

  • In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. Only packets from the management VLAN are transmitted between the AC and APs. Packets from the service VLAN are not allowed between the AC and APs.

Procedure

  1. Configure the network devices.

    [AC] ip route-static 10.23.10.0 24 10.23.100.2
    

  3. Configure the DHCP services to assign IP addresses to APs and STAs.

    # On SwitchB, configure DHCP relay to assign IP addresses on behalf of the AC.
    [SwitchB] dhcp enable
    [SwitchB] interface vlanif 10
    [SwitchB-Vlanif10] ip address 10.23.10.1 24
    [SwitchB-Vlanif10] dhcp select relay

    [SwitchB-Vlanif10] quit
    
    # On SwitchB, configure VLANIF 101 and VLANIF 102 to assign IP addresses to STAs and set the default gateways.
    NOTE:
    Configure the DNS server as required. The common methods are as follows:
    • In interface address pool scenarios, run the dhcp server dns-list ip-address &<1-8> command in the VLANIF interface view.
    • In global address pool scenarios, run the dns-list ip-address &<1-8> command in the IP address pool view.
    [SwitchB] interface vlanif 101
    [SwitchB-Vlanif101] ip address 10.23.101.1 24

    [AC] interface vlanif 100
    [AC-Vlanif100] dhcp select global
    [AC-Vlanif100] quit
    

  4. Configure a VLAN pool for service VLANs.

    # On the AC, create a VLAN pool, add VLAN 101 and VLAN 102 to the pool, and set the VLAN assignment algorithm to hash in the VLAN pool.
    NOTE:

    This example uses the VLAN assignment algorithm hash (default) as an example. If the default setting is not changed before, you do not need to run the assignment hash command.

    In this example, only VLAN 101 and VLAN 102 are added to the VLAN pool. You can use the similar method to add multiple VLANs to a VLAN pool.

    [AC] vlan batch 101 102
    [AC] vlan pool sta-pool
    [AC-vlan-pool-sta-pool] vlan 101 102
    [AC-vlan-pool-sta-pool] assignment hash
    [AC-vlan-pool-sta-pool] quit
    

  5. Configure an AP to go online.

    # Create an AP group to which the APs with the same configuration can be added.
    [AC] wlan
    [AC-wlan-view] ap-group name ap-group1
    [AC-wlan-ap-group-ap-group1] quit
    
    # Create a regulatory domain profile, configure the AC country code in the profile, and apply the profile to the AP group.

    [AC-wlan-view] quit
    
    # Configure the AC's source interface.
    [AC] capwap source interface vlanif 100
    
    # Import the AP offline on the AC and add the AP to AP group ap-group1. Assume that the AP's MAC address is 60de-4476-e360. Configure a name for the AP based on the AP's deployment location, so that you can know where the AP is deployed from its name. For example, name the AP area_1 if it is deployed in Area 1.
    NOTE:

    The default AP authentication mode is MAC address authentication. If the default settings are retained, you do not need to run the ap auth-mode mac-auth command.

    In this example, the AP5030DN is used and has two radios: radio 0 (2.4 GHz radio) and radio 1 (5 GHz radio).

  6. Configure WLAN service parameters.

    # Create security profile wlan-net and set the security policy in the profile.
    NOTE:

    In this example, the security policy is set to WPA-WPA2+PSK+AES and password to a1234567. In actual situations, the security policy must be configured according to service requirements.

    [AC-wlan-view] security-profile name wlan-net
    [AC-wlan-sec-prof-wlan-net] security wpa-wpa2 psk pass-phrase a1234567 aes
    [AC-wlan-sec-prof-wlan-net] quit
    
    # Create SSID profile wlan-net and set the SSID name to wlan-net.
    [AC-wlan-view] ssid-profile name wlan-net
    [AC-wlan-ssid-prof-wlan-net] ssid wlan-net
    [AC-wlan-ssid-prof-wlan-net] quit
    
    # Create VAP profile wlan-net, set the data forwarding mode and service VLAN, and apply the security profile and SSID profile to the VAP profile.

    [AC-wlan-vap-prof-wlan-net] quit
    
    # Bind VAP profile wlan-net to the AP group and apply the profile to radio 0 and radio 1 of the AP.
    [AC-wlan-view] ap-group name ap-group1
    [AC-wlan-ap-group-ap-group1] vap-profile wlan-net wlan 1 radio 0
    [AC-wlan-ap-group-ap-group1] vap-profile wlan-net wlan 1 radio 1
    [AC-wlan-ap-group-ap-group1] quit
    

  7. Configure the AP channel and power.

    NOTE:

    Automatic channel and power calibration functions are enabled by default. The manual channel and power configurations take effect only when these two functions are disabled. The settings of the AP channel and power in this example are for reference only. You need to configure the AP channel and power based on the actual country code and network planning.

    # Disable automatic channel and power calibration functions of radio 0, and configure the channel and power for radio 0.
    [AC-wlan-view] ap-id 0
    [AC-wlan-ap-0] radio 0
    [AC-wlan-radio-0/0] calibrate auto-channel-select disable

    [AC-wlan-radio-0/1] eirp 127
    [AC-wlan-radio-0/1] quit
    [AC-wlan-ap-0] quit

  8. Verify the configuration.

    The AC automatically delivers WLAN service configuration to the AP. After the service configuration is complete, run the display vap ssid wlan-net command. If Status in the command output is displayed as ON, the VAPs have been successfully created on AP radios.

    [AC-wlan-view] display vap ssid wlan-net
