CCNA 4.4 Router Interfaces

• Different Cisco routers have different interface methods
• Interface commands example:

interface e0 (2500)

interface fastethernet 0/0 (2600)

interface serial 0/1/0 (2800)

• No shutdown interface command enables an interface
• Users can check an interfaces' status via show interface or show running-config commands
• To configure IP addresses on an interface, use the ip address command from interface configuration mode
• | (output modifier) command allows user to goto specific ouput within the configurations
• To configure a serial interface, user can use clock rate command to set the clock rate of DCE connection (for DTE with no CSU/DSU)
• show controllers int command allows user to check whether a router has DCE cable connected to it
• Bandwidth command allows user to set data rate on serial link (for EIGRP, OSPF best path calculation)
