Example: Configuring a mesh link between fit APs

Introduction

The following information provides an example of configuring a mesh link between fit APs.

Network configuration

As shown in Figure 1, in centralized forwarding mode, the AC is connected to the switch, and the switch assigns an IP address to APs and clients as a DHCP server. Configure devices to meet the following requirements:

·     AP 1 and AP 2 obtain an IP address from the address pool on VLAN 10 configured on the switch and come online from the AC.

·     The wired client and wireless client are assigned to the same VLAN and are reachable to each other at Layer 2.

Figure 1 Network diagram

 

Restrictions and guidelines

·     Use the actual serial ID of an AP to uniquely identify that AP.

·     To avoid too many packets in VLAN 1, configure GE1/0/4 that connects the switch to AP 1 as a trunk port, and remove the port from VLAN 1.

·     To avoid mesh link errors, do not configure WLAN mesh and auto bandwidth adjustment of WLAN RRM at the same time.

Procedures

Configuring the switch

1.     Configure interfaces on the switch:

# Create VLAN 10 and VLAN-interface 10, and assign an IP address to the VLAN interface. The AC will use this IP address to establish a CAPWAP tunnel with the AP.

<Switch> system-view

[Switch] vlan 10

[Switch-vlan10] quit

[Switch] interface vlan-interface 10

[Switch-Vlan-interface10] ip address 172.16.1.1 255.255.255.0

[Switch-Vlan-interface10] quit

# Create VLAN 20 and VLAN-interface 20, and assign an IP address to the VLAN interface. This VLAN will be used as the gateway for the clients.

[Switch] vlan 20

[Switch-vlan20] quit

[Switch] interface vlan-interface 20

[Switch-Vlan-interface20] ip address 192.168.10.1 255.255.255.0

[Switch-Vlan-interface20] quit

# Configure GigabitEthernet 1/0/1 that connects the switch to the AC as a trunk port, and assign the port to all VLANs.

[Switch] interface gigabitEthernet 1/0/1

[Switch-GigabitEthernet1/0/1] port link-type trunk

[Switch-GigabitEthernet1/0/1] port trunk permit vlan all

[Switch-GigabitEthernet1/0/1] quit

# Configure GigabitEthernet 1/0/4 that connects the switch to AP 1 as a trunk port, remove the port from VLAN 1, and assign the port to all the other VLANs.

[Switch] interface gigabitEthernet 1/0/4

[Switch-GigabitEthernet1/0/4] port link-type trunk

[Switch-GigabitEthernet1/0/4] port trunk permit vlan all

[Switch-GigabitEthernet1/0/4] undo port trunk permit vlan 1

# Set the PVID of GigabitEthernet 1/0/4 to VLAN 10.

[Switch-GigabitEthernet1/0/4] port trunk pvid vlan 10

[Switch-GigabitEthernet1/0/4] quit

# Assign GigabitEthernet 1/0/2 that connects the switch to Client 1 to VLAN 20.

[Switch] interface gigabitEthernet 1/0/2

[Switch-GigabitEthernet1/0/2] port access vlan 20

[Switch-GigabitEthernet1/0/2] quit

[Switch] quit

2.     Configure the DHCP server:

# Enable DHCP.

<Switch> system-view

[Switch] dhcp enable

# Specify 172.16.1.0/24 as the address range for dynamic allocation in DHCP address pool 1, and specify 172.16.1.1 as the gateway address.

[Switch] dhcp server ip-pool 1

[Switch-dhcp-pool-1] network 172.16.1.0 mask 255.255.255.0

[Switch-dhcp-pool-1] gateway-list 172.16.1.1

# Exclude 172.16.1.2 from dynamic allocation.

[Switch-dhcp-pool-1] forbidden-ip 172.16.1.2

[Switch-dhcp-pool-1] quit

# Configure DHCP address pool 2. In the address pool, specify 192.168.10.1 as the gateway IP address, 192.168.10.0/24 as the subnet for dynamic allocation, and 192.168.10.1 as the DNS server address.

[Switch] dhcp server ip-pool 2

[Switch-dhcp-pool-2] network 192.168.10.0 mask 255.255.255.0

[Switch-dhcp-pool-2] gateway-list 192.168.10.1

[Switch-dhcp-pool-2] dns-list 192.168.10.1

[Switch-dhcp-pool-2] quit

Configuring the AC

1.     Configure interfaces on the AC:

# Create VLAN 10 and VLAN-interface 10, and assign an IP address to the VLAN interface. The AC will use this IP address to establish a CAPWAP tunnel with the AP.

[AC] vlan 10

[AC-vlan10] quit

[AC] interface vlan-interface 10

[AC-Vlan-interface10] ip address 172.16.1.2 255.255.255.0

[AC-Vlan-interface10] quit

# Create VLAN 20.

[AC] vlan 20

[AC-vlan20] quit

# Configure GigabitEthernet 1/0/1 that connects the AC to the switch as a trunk port, and assign the port to all VLANs.

[AC] interface gigabitethernet 1/0/1

[AC-GigabitEthernet1/0/1] port link-type trunk

[AC-GigabitEthernet1/0/1] port trunk permit vlan all

[AC-GigabitEthernet1/0/1] quit

2.     Configure a wireless service:

# Create service template office.

# Set the SSID to Documents.

[AC-wlan-st-office] ssid Documents

# Specify VLAN 20 for the service. Clients will join the VLAN after coming online from the service.

[AC-wlan-st-office] vlan 20

# Set the AKM mode to PSK, and specify the plaintext preshared key as 12345678.

[AC-wlan-st-office] akm mode psk

[AC-wlan-st-office] preshared-key pass-phrase simple 12345678

# Set the cipher suite to CCMP and set the security IE to WPA.

# Configure the AC to forward client data traffic. If the AC acts as the client traffic forwarder by default, skip this step.

[AC-wlan-st-office] client forwarding-location ac

# Enable the service template.

[AC-wlan-st-office] service-template enable

[AC-wlan-st-office] quit

3.     Configure AP 1:

# Set the mesh ID to 1.

[AC-wlan-mesh-profile-1] mesh-id 1

# Set the authentication and key management (AKM) mode to sae.

[AC-wlan-mesh-profile-1] akm mode sae

# Configure simple character string meshlink as the PSK.

[AC-wlan-mesh-profile-1] preshared-key pass-phrase simple meshlink

# Enable the mesh profile.

[AC-wlan-mesh-profile-1] mesh-profile enable

[AC-wlan-mesh-profile-1] quit

# Bind radio 1 in AP group group1 to mesh profile 1. Bind radio 1 in AP group group2 to mesh profile 1 in the same way.

[AC] wlan ap-group group1
