I am sorry,what's is VCI,is it DHCP Option 43 Vendor Class Identifier (VCI) ? If so,i configure dhcp server by cisco document as below:https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/97066-dhcp-option-43-00.html ... View more

I don't have any other config of dhcp,at the beginning,i don't config the dhcp option43,other aps can work noraml after obtain ip address from dhcp server,only ap2802 need configure wlc's ip address by "capwap ap ..." command,then,it can be work.So,i doubt whether ap16 & ap27 discovery process difference with ap2800.But i didn't find any reason to explain this symptom,because i didn't face this issue before. ...

OK ,got it,thanks for your help. I config the dhcp with option43,AP can get wlc's ip address,and send discovery to wlc,ap2700 and ap1600 can work well,but ap2800 cannot work normal.i don't know how to confirm the L2 or L3 discovery process.. ... View more

Hi all, Thanks for your reply,i have connected ap2802 to another switch,it can be work well,but we must config wlc's ip address on ap2802 for join wlc.We also have some ap1602 and ap2702,they can join to wlc after obtain ip address.So i don't know whether there are some limitation of ap2802.At a same switch,other aps can work normal,ap2802 cannot work as them,and need config a ip address of wlc.... ...
