Hello everyone,
Today I will share with you how to deal with users who cannot get an IP address from AR used as AC.
Issue Description
users cannot get ip address from AR used as AC
Topo
AR---Simple switch---AP---Client
Key configuration
AR downlink interface:
interface GigabitEthernet0/0/2
port link-type trunk
port trunk pvid vlan 888
port trunk allow-pass vlan 888 to 889
VAP-profile for WLAN:
vap-profile name huawei
service-vlan vlan-id 889
ssid-profile huawei
security-profile huawei
Handling Process
As the customer described, the switch between AR and AP is a simple switch, and vlan888 is for managing the switch, so need to configure PVID on AR to manage the switch since the simple switch cannot identify service packets with VLAN.
so the service-vlan 889 cannot be transferred by the simple switch, so the terminal cannot get ip address from AR
Root Cause
the service-vlan 889 cannot be transferred by the simple switch since it cannot identify service packets with VLAN, so the terminal cannot get ip address from AR
Solution
Change the forwarding mode to tunnel forwarding so that service packets are transmitted through the tunnel without passing through the simple switch, then solve this issue
That is all I want to share with you! Thank you!
