cisco配置手记（The Cisco configuration notes） The Cisco configuration notes Existing devices: CISCO routers, 2620XM (4 units) and 2621XM (5 units), 3750, three layer switches, PIX-515E firewall, CISCO2950 two layer switch (9 units) Key commands: commands, sets, and commands that have security, control, monitoring, monitoring, and testing capabilities One or two layer switch 1, the basic configuration (1) set the IP address of the VLAN1, the mask: To configure： SW itch#config terminal (config) #interface vlan1! Enter the interface to configure the IP (config-if) #ip, address, 53 (IP), (mask)! Setting parameter number Verification： (config-if) #exit Switch#show interface vlan1 Save settings: Switch#copy, running-config, startup-config? (2) dividing VLAN To configure： Switch#vlan database (another way)! Create a VLAN Switch#vlan 2 Switch#exit Switch#config terminal One port: (config) #interface fastethernet0/0! Enter the port to be divided (config-if) #switchport access VLAN 2! Divide into a VLAN Multiports: (config) #interface, range, fastethernet0/0, -7! Enter into the end to be collectively divided mouth (config-if) #switchport access VLAN 2! Divide into a VLAN Verification： Switch#show VLAN Preservation： Switch#copy running-config startup-config (3) setting up trunk To configure： Switch#config terminal (config) #interface gigabitethernet0/1! Enter an interface to configure a trunk road (config-if) #switchport, mode, trunk! Set up arterial road Verification： Switch#show interface trunk Preservation： Switch#copy running-config startup-config (4) connection router If there are multiple VLAN on the switch, the router interface must have multiple IP addresses. Use a child The interface sets multiple IP addresses. The interface to the router should be set to trunk and sealed Protocol: ISL, or 802.1Q. Configuration switch: Switch#config terminal (config) #interface gigabitethernet0/1 (config-if) #switchport mode trunk, which is configured as a trunk road, automatically encaps
