# 配置AC的源接口。

[AC] capwap source interface vlanif 100

V200R021C00版本开始，配置CAPWAP源接口或源地址时，会检查和安全相关的配置是否已存在，包括DTLS加密的PSK、AC间DTLS加密的PSK、登录AP的用户名和密码、全局离线管理VAP的接入密码，均已存在才能成功配置，否则会提示用户先完成相关的配置。

Set the DTLS PSK(contains 8-32 plain-text characters, or 48 or 68 cipher-text characters that must be a combination of at least two
of the following: lowercase letters a to z, uppercase letters A to Z, digits, and special characters):   //配置DTLS加密的PSK

Warning: Ensure that the management VLAN and service VLAN are different. Otherwise, services may be interrupted.
Warning: Before an added device goes online for the first time, enable DTLS no-auth if it runs a version earlier than V200R021C00 or
enable DTLS certificate-mandatory-match if it runs V200R021C00 or later.
[AC] capwap dtls no-auth enable  //V200R021C00版本开始，AC默认开启CAPWAP控制隧道的DTLS加密功能。添加AP时AP会上线失败，此时需要先开启CAPWAP DTLS不认证方式让AP上线，以便AP获取安全凭证，AP上线后应及时关闭该功能（undo capwap dtls no-auth enable），避免未授权AP上线。
Warning: This operation allows for device access in non-DTLS encryption mode even when DTLS is enabled and brings security risks. Af
ter the device goes online for the first time, disable this function to prevent security risks. Continue?[Y/N]:y
# 在AC上离线导入AP，并将AP加入AP组“ap-group1”中。假设AP的MAC地址为bc76-c55d-bc30，并且根据AP的部署位置为AP配置名称，便于从名称上就能够了解AP的部署位置。例如MAC地址为bc76-c55d-bc30的AP部署在1号区域，命名此AP为area_1。
