Introduction

The following information provides an example for configuring dual-uplink interfaces to provide increased link bandwidth and load sharing.

Prerequisites

The document applies to Comware 7-based access controllers and access points. Procedures and information in the examples might be slightly different depending on the software or hardware version of the access controllers and access points.

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of DHCP, WLAN access, Ethernet link aggregation, and port isolation.

Example: Configuring dual-uplink interfaces

Network configuration

As shown in Figure 1, in centralized forwarding mode, the AC is connected to the access switch in hair-pin mode. The DHCP server assigns IP addresses to the AP and the client.

·     Configure the client to come online in VLAN 200.

·     Assign the AC to VLAN 100, and configure the AC and the AP to establish connections at Layer 2.

·     Configure Layer 2 static link aggregation for the two uplink interfaces connecting the AP and the access switch. Configure load balancing based on source and destination MAC addresses for data traffic to be load balanced among different member ports of the aggregation.

You can configure the load balancing mode as needed. This example is for illustration only.

Figure 1 Network diagram

 

Analysis

·     Enable the DHCP server feature on the core switch for the core switch to act as the DHCP server.

·     Enable PoE on the access switch to supply power to the AP.

·     Configure wireless services on the AC for the client to access the network wirelessly.

Restrictions and guidelines

·     Use the serial ID labeled on the AP's rear panel to specify an AP.

·     Forbids VLAN 1 traffic to be transmitted out of trunk ports to prevent packet accumulation in VLAN 1.

·     As a best practice, use AP uplink interfaces that have the same port rate for link aggregation, and make sure the two peer interfaces on the switch also use the port rate. If the AP uplink interfaces use different port rates, only one interface can forward packets at a time, which increases link availability but disables load balancing.

Procedures

Configuring the core switch

1.     Configure interfaces on the core switch:

# Create VLAN 100 and VLAN-interface 100, and assign an IP address to the VLAN interface. The AP will obtain an IP address from the address pool matching the interface address.

<Core switch> system-view

[Core switch] vlan 100

[Core switch-vlan100] quit

[Core switch] interface vlan-interface 100

[Core switch-Vlan-interface100] ip address 192.168.10.1 255.255.255.0

[Core switch-Vlan-interface100] quit

# Create VLAN 200 and VLAN-interface 200, and assign an IP address to the VLAN interface. The client will obtain an IP address from the address pool matching the interface address.

[Core switch] vlan 200

[Core switch-vlan200] quit

[Core switch] interface vlan-interface 200

[Core switch-Vlan-interface200] ip address 192.168.20.1 255.255.255.0

[Core switch-Vlan-interface200] quit

# Configure Ten-GigabitEthernet 1/0/23 that connects the core switch to the access switch as a trunk port, remove the port from VLAN 1, and assign the port to VLANs 100 and 200.

[Core switch] interface ten-gigabitethernet 1/0/23

[Core switch-Ten-GigabitEthernet1/0/23] port link-type trunk

[Core switch-Ten-GigabitEthernet1/0/23] undo port trunk permit vlan 1

[Core switch-Ten-GigabitEthernet1/0/23] port trunk permit vlan 100 200

[Core switch-Ten-GigabitEthernet1/0/23] quit

2.     Configure the default route. (Details not shown.)

3.     Configure the DHCP server:

# Enable the DHCP server feature.

[Core switch] dhcp enable

# Configure DHCP address pool 1, specify subnet 192.168.10.0/24, and set the gateway address as 192.168.10.1.

[Core switch] dhcp server ip-pool 1

[Core switch-dhcp-pool-1] network 192.168.10.0 mask 255.255.255.0

[Core switch-dhcp-pool-1] gateway-list 192.168.10.1

# Exclude 192.168.10.2 (IP address of VLAN-interface 100 of the AC) from IP allocation.

[Core switch-dhcp-pool-1] forbidden-ip 192.168.10.2

[Core switch-dhcp-pool-1] quit

# Configure DHCP address pool 2, specify subnet 192.168.20.0/24, set the gateway address, and specify the DNS server address. In this example, the DNS server address is also 192.168.20.1.

[Core switch] dhcp server ip-pool 2

[Core switch-dhcp-pool-2] network 192.168.20.0 mask 255.255.255.0

[Core switch-dhcp-pool-2] gateway-list 192.168.20.1

[Core switch-dhcp-pool-2] dns-list 192.168.20.1

[Core switch-dhcp-pool-2] quit

Configuring the AC

1.     Edit the AP configuration file.

# Edit the AP configuration file, name the file map.txt, and upload the file to the AC.
