排查步骤：
1. 检查GigabitEthernet1/0/7端口配置，确认是否为AP接入端口，是否启用边缘端口（edge port）：
display stp interface GigabitEthernet1/0/7
2. 若未配置边缘端口，AP可能发送BPDU（部分AP或中间设备误发），需配置边缘端口并开启BPDU保护：
interface GigabitEthernet1/0/7
stp edged-port enable
stp bpdu-protection
3. 若已配置边缘端口仍收到BPDU，检查AP侧是否有环路或其他设备接入该端口，可抓包分析端口流量：
packet-capture interface GigabitEthernet1/0/7 destination file flash:/bpdu.cap count 100
4. 检查STP计算是否正常，确认该端口角色及优先级：
display stp instance 0 brief
5. 若存在dispute，可能是端口收到低优先级BPDU导致，可调整端口STP优先级或确认上游设备配置：
interface GigabitEthernet1/0/7
stp port priority 4096（根据网络调整）

我自己问题，我自己接了模拟器把网卡桥接到无线网卡上，我无线网卡接入这个AP，当我启用模拟器的交换机会发出bpdu.所以这个7口收到了。
