与生成树有关的配置如下:
spanning-tree vlan 110 priority 28672
interface Ethernet102/1/13
switchport
switchport access vlan 12
no shutdown
interface Ethernet102/1/15
switchport
switchport access vlan 12
no shutdown
N7K_01# show span sum
Switch is in rapid-pvst mode
Root bridge for: VLAN0012, VLAN0110, VLAN0780, VLAN0800
Port Type Default is disable
Edge Port [PortFast] BPDU Guard Default is disabled
Edge Port [PortFast] BPDU Filter Default is disabled
Bridge Assurance is enabled
Loopguard Default is disabled
Pathcost method used is short
STP-Lite is enabled
日志如下:
Ethernet102/1/13与Ethernet102/1/15这两个端口之前没有使用,昨天施工跳线才用到这两个端口。
昨出现了几秒临时闪断,我看了下日志,其他都正常,只有BPDU Guard的日志有点儿可疑,正好当时有施工人员在机房跳线,一开始怀疑是不是端口启用了边缘端口,出现临时环路引起中断,然后BPDU Guard功能强制关闭了这两个端口,阻断了环路,网络恢复正常,这样引起的几秒临时闪断,但是今天来现场看了下配置,发端口没有配置边缘端口,也没有启用BPDU Guard功能。
请问,为什么日志你会产生BPDU Guard的日志?
