Example: Configuring a mesh link between a fit AP and a fat AP

Introduction

The following information provides an example of configuring a mesh link between a fit AP and a fat AP.

Network configuration

As shown in Figure 1, in centralized forwarding mode, the AC in LAN 1 is connected to Switch 1, and Switch 1 assigns an IP address to the AP and client in LAN 1 as a DHCP server. Switch 2 assigns an IP address to the client in LAN 2 as a DHCP server. Configure the devices to meet the following requirements:

·     AP 1 obtains an IP address from the address pool on VLAN 10 configured on Switch 1 and comes online from the AC.

·     The clients in LAN 1 and LAN 2 are assigned to different VLANs and are reachable to each other at Layer 3.

Figure 1 Network diagram

 

Restrictions and guidelines

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

·     Configure GE 1/0/4 that connects Switch 1 to the AP 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 Switch 1

1.     Configure interfaces on Switch 1:

# 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.

<Switch1> system-view

[Switch1] vlan 10

[Switch1-vlan10] quit

[Switch1] interface vlan-interface 10

[Switch1-Vlan-interface10] ip address 172.16.1.1 255.255.255.0

[Switch1-Vlan-interface10] quit

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

[Switch1] vlan 20

[Switch1-vlan20] quit

[Switch1] interface vlan-interface 20

[Switch1-Vlan-interface20] ip address 192.168.10.1 255.255.255.0

[Switch1-Vlan-interface20] quit

# Create VLAN 30 and VLAN-interface 30, and assign an IP address to the VLAN interface. The switch will use this VLAN to communicate with the AP.

[Switch1] vlan 30

[Switch1-vlan30] quit

[Switch1] interface vlan-interface 30

[Switch1-Vlan-interface30] ip address 10.12.12.1 255.255.255.0

[Switch1-Vlan-interface30] quit

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

[Switch1] interface gigabitEthernet 1/0/1

[Switch1-GigabitEthernet1/0/1] port link-type trunk

[Switch1-GigabitEthernet1/0/1] port trunk permit vlan all

[Switch1-GigabitEthernet1/0/1] quit

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

[Switch1] interface gigabitEthernet 1/0/4

[Switch1-GigabitEthernet1/0/4] port link-type trunk

[Switch1-GigabitEthernet1/0/4] port trunk permit vlan all

[Switch1-GigabitEthernet1/0/4] undo port trunk permit vlan 1

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

[Switch1-GigabitEthernet1/0/4] port trunk pvid vlan 10

[Switch1-GigabitEthernet1/0/4] quit

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

[Switch1] interface gigabitEthernet 1/0/2

[Switch1-GigabitEthernet1/0/2] port access vlan 20

[Switch1-GigabitEthernet1/0/2] quit

[Switch1] quit

2.     Configure the DHCP server:

# Enable DHCP.

<Switch1> system-view

[Switch1] 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.

[Switch1] dhcp server ip-pool 1

[Switch1-dhcp-pool-1] network 172.16.1.0 mask 255.255.255.0

[Switch1-dhcp-pool-1] gateway-list 172.16.1.1

# Exclude 172.16.1.2 from dynamic allocation.

[Switch1-dhcp-pool-1] forbidden-ip 172.16.1.2

[Switch1-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.

<AC> display wlan ap name ap1

                                  AP information

 State : I = Idle,      J  = Join,       JA = JoinAck,    IL = ImageLoad

         C = Config,    DC = DataCheck,  R  = Run,   M = Master,  B = Backup

 

AP name                        APID  State Model           Serial ID

ap1                            1     R/M   WA6330          219801A23V8192E00021

2.     Display mesh link information on the fat AP:

<AP2> display wlan mesh-link

Peer MAC       RSSI BSSID          Interface         Link state       Online time

542b-dea7-a8c0 81   d461-fe59-4d20 WLAN-MeshLink2    Active(an)       20h 00m 49s

3.     Ping Client 2 from Client 1 to verify that they are reachable to each other.
