网络工程 - (Cisco/Apple) 802.11r Handoffs Failing: 802.11r Key Cache lookup failed in (re)-assoc req - 吾爱随笔录

我正在尝试在运行软件版本 8.2.160.0 的虚拟 WLC 上使用两个 Cisco 3602i AP 设置无线 LAN。我的目标是让 iPhone 6s 使用 Voice-over-WiFi 能够在这两个使用 802.11r/802.11k/802.11v 的 AP 之间快速漫游，而不会掉线。

据我所知，我已经根据 Cisco 和 Apple 的建议为此设置了一切，但切换不断失败。当切换尝试失败时，在控制器上运行“调试客户端 <iphone-mac-address>”会产生以下消息：

在 REAP AP BSSID 44:ad:d9:8e:8b:fe (slot 1) 上关联失败，状态 11 0 802.11r 密钥缓存查找在 (re)-assoc req 中失败

不幸的是，谷歌搜索“key cache lookup failed”只返回一个结果——一个未注释的pastebin转储。

以下是相关 WLAN 的 vWLC 配置，id '2'，SSID 'phone-test-5g'：
