引导节点时 TFTP 超时 (Mirantis Openstack)

Question

我有一个关于 TFTP 服务器的奇怪问题。当我尝试启动我的裸机 Dell R710 以向 Mirantis Openstack 提供新角色时，我得到：

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 NIC - Broadcom NetXtream II 卡请从 tftp/dhcp 服务器（fuel master）找到下面的 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
listening on eth0, link-type EN10MB (Ethernet), capture size 262144 bytes

Answer 1

问题已解决。看起来我们的网络中有一个 wds 服务也在监听这个子网。
