HP 2510G Loop Protect不起作用

HP 2510G交换机上的环路保护存在问题。

我configuration了Loop-Protect和loop-protect all receiver-action send-disable并设置了transmit-interval 1和disable-timer 30 。

我testing了我的设置：
端口1处的客户端1端口2处的客户端2。
然后，我用端子电缆直接连接端口3和4。
Loop被检测到的次数最多，而Port 3和Port 4则下降了。
从来没有检测到14个环路中的2个，networking将被淹没。

什么可能是错误？

• 切换消除了碰撞。 但是关于
• 基本的商业networking问题，我该怎么办？
• Dell PowerConnect机架耳朵的螺丝尺寸是多less？
• 戴尔X4012铜缆选项？
• Linksys /思科小型企业SRW系列（即SRW248G4） – 克服限制

下面是show loop-protect的输出：
