Time-domain reflectometer (TDR): 拿Cisco Switch 當作測試線路工具

當然, 並不是敎大家真的花很多的"小朋友"買Cisco Switch 只當作測試線路工具. 如果你已經安裝了以下這些Switch: Catalyst 2960, 2970, 3560/3560-E, 3750/3750-E. 那可就要好好利用這項功能!

啟動TDR測試:

Switch# test cable-diagnostics tdr interface gigabitethernet0/2
TDR test started on interface Gi0/2


Switch#show cable-diagnostics tdr interface gigabitEthernet 0/2
TDR test last run on: Dec 10 09:05:10

支援硬體: Catalyst 2960, 2970, 3560/3560-E, 3750/3750-E
