Network Topology
In general networking, the AP and AC are registered across the public network. When the communication between the AP and AC is disconnected, the terminal can search for the SSID, but cannot access it. After the communication between AP and AC is restored, the terminal can access the Internet normally.
Problem Description
In general networking, the AP and AC are registered across the public network. When the communication between the AP and AC is disconnected, the terminal can search for the SSID, but cannot access it. After the communication between AP and AC is restored, the terminal can access the Internet normally.
Process Analysis
1. From the phenomenon, we can determine that it is not an AP failure, nor is it a terminal NIC problem or compatibility.
2. Check the AC configuration, we found that remote AP configuration is incomplete, local forwarding is configured under the service template, AP configured hybrid-remote-ap enable. But no association point and authentication point are configured.
# After the association between AP and AC is lost, enable the AP local association function.
[AC-wlan-st-1] client association-location ap
//By default, the association location of the client is on the AC.
# Enable authentication on the AP after the association between the AP and the AC is lost.
[AC-wlan-st-1] client-security authentication-location ap
//By default, the WLAN user access authentication location is on the AC.
Solution
After completing the configuration, test that the remote AP function is normal.
Note:
1. If you want the new terminal to be online in remote status, you need to configure the authentication point and association point to be local.
2. If you want the old terminal to continue to forward data packets in the remote situation, you must configure local forwarding from the beginning. In this way, when the AP and the AC disconnect the tunnel and enter the remote state, the data forwarding of the old terminal will not be affected.
3. The remote AP function only takes effect when the AP is offline. Remote AP does not take effect when AP is online.
