引导节点时的TFTP超时（Mirantis Openstack）

Question

我有一个TFTP服务器的奇怪问题。当我试图启动我的裸机Dell R710为Mirantis Openstack配置新角色时，我得到了：

CLIENT MAC ADDR: ....
CLIENT IP: ...
GATEWAY IP: ...
PXE-E32: TFTP open timeout

但最奇怪的是服务器会在一段时间后（几个小时内）成功启动。我们正在使用集成的NIC - Broadcom NetXtream II卡请在下面找到tcpp / dhcp服务器（燃料主机）的tcpdump：

[root@fuel2 ~]# sudo tcpdump ether host d0:67:xx:xx:xx:xx
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

Answer 1

问题解决了。看起来我们的网络中也有wds服务正在监听这个子网。
