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!

I am very interested for this post, Thanks for you sharing . I have a suggest ,The intermediate Layer 2 device must release the service VLAN. It is recommended that the device configuration be checked first when it is deployed.

users cannot get ip address from AR used as AC. It can be described as a word and a classic sentence, which is a model that my generation should learn. I am very interested for this post, which is very helpful to our daily troubleshooting.When many hosts are distributed on an internal network, the internal host IDs can be divided into multiple subnet IDs to facilitate management. A network can be divided into multiple subnets to conserve IP address space and support flexible IP addressing. This post was last edited by yangyong at 2018-10-31 08:14.
