Wireless controller HA DHCP FAIL 這個目前是debug,
Internal DHCP is not supported when SSO is enabled.<===請問這個多久會修復

当SSO开启的时候,内部DHCP不会支持。短期以内也不会有修复。
我们不建议在大型部署环境中使用内部DHCP; 这个功能只是给一些小型部署环境准备的,比如实验环境。

Internal DHCP 基本開啟在AP 取的IP使用,變成客戶既有的架構就要修改了。
使用外部DHCP Server取得不到IP,想請問一下DHCP 設定在介面內部的DHCP,因該沒有其他地方可以設定了吧!!

问题的后半部分没看明白。根据以上描述,我认为你应该排查为什么使用外部DHCP Server取得不到IP。
检查DHCP Server工作是否正常,是配置的问题还是网络原因?
如有必要,建议开TAC case以作进一步排查。

上段設備為N5k,疑似沒有DHCP relay server 設定所以在另外一個網段架設DHCP server無法轉送封包,
目前會再另外再controller 網段架設DHCP Server.
屆時再做測試
N5k設定值
service dhcp
ip dhcp relay
ip dhcp relay information option
ip dhcp relay information option vpn
