Cisco Switch 密碼還原

手上的Cisco 2950 Switch設了密碼，猜了半天也進不去，重開後按Ctrl+Break也無反應，還在懷疑是不是線壞掉的時候，Google了一下.....原來Switch密碼還原和Router完全不同

1. 按住Switch上的Mode鍵，並將Switch開機


2.此時Switch會出現以下訊息，紅字為輸入的文字
C2950 Boot Loader (C2950-HBOOT-M) Version 12.1(11r)EA1, RELEASE SOFTWARE (fc1)

HP A5120 Switch 基本設定

沒用過HP的Switch，指令跟Cisco完全不同，花了一些時間熟悉~ 1.啟動Spanning-Tree，預設沒有開啟 (黑色粗體是我敲的指令) <HP> system-view System View: return to User View with Ctrl+Z.

Cisco Switch 發生Loopback

User告知網路無法使用，看了Switch的狀況後，發現那個Port的狀態是Error Disable，接著又看了Switch的log Feb  8 12:14:14 TW: %DHCP_SNOOPING-5-DHCP_SNOOPING_UNTRUSTED_PORT: DHCP_SNOOPING drop message on untrusted port, message type: DHCPNAK, MAC sa: 2c56.dc86.xxxx Feb  8 12:15:49 TW: %DHCP_SNOOPING-5-DHCP_SNOOPING_UNTRUSTED_PORT: DHCP_SNOOPING drop message on untrusted port, message type: DHCPNAK, MAC sa: 2c56.dc86.xxxx Feb  8 12:18:00 TW: %ETHCNTR-3-LOOP_BACK_DETECTED: Keepalive packet loop-back detected on FastEthernet0/10. Feb  8 12:18:00 TW: %PM-4-ERR_DISABLE: loopback error detected on Fa0/10, putting Fa0/10 in err-disable state Feb  8 12:18:01 TW: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/10, changed state to down Feb  8 12:18:02 TW: %LINK-3-UPDOWN: Interface FastEthernet0/10, changed state to down 應該是User私接設備，除了造成Loopback之外，又在隨便發放IP....... 不過因為那個User比較特殊，先教育了一下之後，再把那個Port shutdown , no shutdown，接著把Recovery設了上去，下次如果再遇到相同狀況，10分鐘後會自動恢復 xxx...
