V5版本的H3C成都 AP WA4320-ACN-SI-FIT在V7設(shè)備810路由器上注冊(cè)上線失敗。AP能夠正常獲取IP地址，且路由器能ping通AP，路由器與AP直連進(jìn)行二層注冊(cè)。

　　debug信息如下，

　　LWPC是V5設(shè)備建立隧道的debug標(biāo)志，CWS是V7設(shè)備建立隧道的debug標(biāo)志。從AP的debug信息可以看出，AP支持雙隧道協(xié)議，發(fā)送了LWAPP隧道和CAPWAP隧道的Discovery Request報(bào)文。810路由器的debug信息顯示，路由器僅接收了CAPWAP隧道的Discovery Request報(bào)文，并進(jìn)行了處理，沒(méi)有看到關(guān)于LWAPP隧道的報(bào)文信息。AP收到了路由器回復(fù)的CAPWAP Discovery Response，但沒(méi)有對(duì)該報(bào)文進(jìn)行處理。

　　因此懷疑是AP與810路由器跨平臺(tái)注冊(cè)時(shí)，版本不能兼容，導(dǎo)致路由器發(fā)送的報(bào)文不能被AP識(shí)別，然后將報(bào)文丟棄。

　　建議現(xiàn)場(chǎng)先將AP手動(dòng)刷到V7版本，然后再在810上注冊(cè)，客戶表示如此操作之后成功上線。

　　810路由器在管理AP時(shí)，不注冊(cè)license默認(rèn)可以管理2個(gè)AP，不支持跨平臺(tái)進(jìn)行注冊(cè)操作。
