ADCampus network AP can not be online

Not involved

Site is ADCampus environment networking, 

AP can not register online

After confirming the problem immediately after the analysis, the bureau point exists more than one building, only two of theleaf under the access connected to the AP can not be online. First confirm whether the AP to obtain the address and DHCP address pool location. 

Check found that the AP can not go online are in the I state, partly not seen on the AC, login to the AP found that the AP constantly reboot, vlan interface under the address is not obtained. 

The site network is assigned through DHCP relay, check the existence of dhcp-relay under the corresponding interface on LEAF Further debug dhcp-relay found no dhcp request from AP, suspecting that layer 2 is not working. 

Because the vxlan network is involved, check the mapping of vlan 4093 and vsi4093 and find that 4093 is not associated with vlan 4093 in the service instance, so the message cannot be encapsulated in vxlan.

Solved after adding vlan4093 message identification and correlation.
