AP can't register with AC in the SVF

Publication Date:  2016-08-26 Views:  193 Downloads:  0
Issue Description

 AP can’t join to a AC in SVF switch. the Parent switch is s12708 and the AS switch is s5700Li, the SVF had been configured in the switch and run well.
 AP connect to AS switch and confim the POE and wire line connection is well. but the AP can’t join to AC.
 AP can get the ip address from dhcp server.


Handling Process

check the configuration and network topology.

 There are two s12708 switchs, one is located at IVFO and another is located at Burns, each s12708 as one parent switch and connect to many s5700Li switch with SVF, the s5700Li switch as AS switch .
 IVFO CAPWAP VLAN 400 for SVF,the gateway IP address is 10.40.0.1 and the DHCP poo option 43 = 10.40.0.1;
 Burns CAPWAP VLAN 300 for SVF,the gateway IP address is 10.30.0.1 and the DHCP pool option 43 = 10.30.0.1;
 the AC is two X1E line cards which are installed on the s12708 in IVFO and confirm it running well.
 AS switch join the parent switch with capwap protocol and the ip register address is reachable and the physical link is well.
 confirm the ap are new device and no fault in the transporation, the power light blink is right when connect the ap to a POE swich.


Root Cause
the SVF management vlan is the same with wifi management vlan. and also use the same protocol to register to parent device and AC. so the AP conn't register the AC .
Solution
modify the wifi management vlan ,AP use the different vlan and ip address to register AC.
Suggestions
have a good the network plan, well konw about the protocol of the interconnection.
