使用Cisco L3 Switch做VLAN的Routing

目標: 讓VLAN100與VLAN200的電腦透過L3 Swtich做VLAN的Routing,並且可以互相存取資源與上網,另外再使用Windows Server 2012配發VLAN100,VLAN200的IP Firewall: 使用ASUS AP當Firewall,並設兩條Static Route Switch: Core Switch為Cisco 3750切VLAN 10,VLAN100,VLAN200,VLAN10為預設的VLAN,VLAN100為Sales,VLAN200為RD Edge Switch為Cisco 3750與2950,其中2950為VLAN100,3750為VLAN200,如果要By Port切VLAN也可以,這裡只是為了方便說明,所以Edge Switch都直接設為單一VLAN Core Switch的設定 原本我只想Show Running-config其中比較重要的設定,後來想想還是全部列出,用紅色標記重要的設定 Gi 1/0/1接2950 Gi 1/0/2接3750 Gi 1/0/24接Router Core-3750#show running-config Building configuration...

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...
