4.1.3 Example for Enabling an AP to Go Online Using a Static IP Address
Networking Requirements
As shown in Figure 4-2, the AC is connected to an aggregation switch in inline or bypass mode. Before configuring the WLAN service, enable APs to go online on the AC.
Configuration Roadmap
- Configure the AC and AP to enable them to communicate with each other.
- Configure global parameters on the AC.
- Configure the authentication mode for the AP.
- Configure a static IP address for the AP and enable the AP to go online.
Configuration Notes
- The AP needs to go online using a static IP address; therefore, you need to log in to the AP to configure it.
-
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 on WLAN-ESS interfaces of the AC.
-
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 betweeen the AC and APs. Packets from the service VLAN are not allowed between the AC and APs.
Procedure
- Configure the AC and APs to communicate.
- Configure AC system parameters.
# Configure the country code.
[AC] wlan ac-global country-code cn Warning: Modify the country code may delete configuration on those AP which us e the global country code and reset them, are you sure to continue?[Y/N]:y
# Configure the AC ID and carrier ID.
[AC] wlan ac-global ac id 1 carrier id other
# Configure the source interface.
[AC] wlan [AC-wlan-view] wlan ac source interface vlanif 100
- Set the AP authentication mode.
# Set AP authentication mode to MAC address authentication.
[AC-wlan-view] ap-auth-mode mac-auth
# Query the AP device type.

- Log in to the AP using the serial port and configure a static IP address for the AP.
# Configure the AP static IP address and AC IP address.

- Verify the configuration.
# Run the display ap all and display ap-run-info id 1 command to display information about online APs.
