Backing Up the Cisco Router Configuration To copy the router’s configuration from a router to a TFTP server, you can use either the copy running-config tftp or the copy startup-config tftp command. Either one will back up the router configuration that’s currently running in DRAM, or that’s stored in NVRAM. Verifying the Current Configuration To verify the configuration in DRAM, use the show running-config command (sh run for short) like this: Router#sh run Building configuration… Current configuration: ! version 12.0 The current configuration information indicates that the router is now running version 12.0 of the IOS. Verifying the Stored Configuration Next, you should check the configuration stored in NVRAM. To see this, use the show startup-config command (sh start for short) like this: Router#sh start Using 366 out of 32762 bytes ! version 11.2 The second line shows you how much room your backup configuration is using. Here, we can see that NVRAM is 32KB and that only 366 bytes

To make changes to an interface, you use the interface command from global configuration mode: Router(config)#interface ? Async Async interface BVI Bridge-Group Virtual Interface CTunnel CTunnel interface Dialer Dialer interface FastEthernet FastEthernet IEEE 802.3 Group-Async Async Group interface Lex Lex interface Loopback Loopback interface MFR Multilink Frame Relay bundle interface Multilink Multilink-group interface Null Null interface Serial Serial Interface Tunnel Tunnel interface Vif PGM Multicast Host interface Virtual-Template Virtual Template interface Virtual-TokenRing Virtual TokenRing Interface range interface range command Router(config)#interface fastethernet 0/0 Router(config-if)# Did you notice that the prompt changed to Router(config-if)#? This tells you that you’re in interface configuration mode. And wouldn’t it be nice if the prompt also gave you an indication of what interface you were configuring? Well, at l

There are five passwords used to secure your Cisco routers: console, auxiliary, telnet (VTY), enable password, and enable secret. Just as you learned earlier in the chapter, the first two passwords are used to set your enable password that’s used to secure privileged mode. This will prompt a user for a password when the enable command is used. The other three are used to configure a password when user mode is accessed either through the console port, through the auxiliary port, or via Telnet. Enable Passwords You can set the enable passwords from global configuration mode like this: Router(config)#enable ? last-resort Define enable action if no TACACS servers respond password Assign the privileged level password secret Assign the privileged level secret use-tacacs Use TACACS to check enable passwords The following points describe the enable password parameters: Last-resort Allows you to still enter the router if you set up authentication through a TACACS server and it’s not avail

LAN switch types decide how a frame is handled when it’s received on a switch port. Latency– the time it takes for a frame to be sent out an exit port once the switch receives the frame– depends on the chosen switching mode. There are three switching modes: Cut-through (FastForward) When in this mode, the switch only waits for the destination hardware address to be received before it looks up the destination address in the MAC filter table. Cisco sometimes calls this the FastForward method. FragmentFree (modified cut-through) This is the default mode for the Catalyst 1900 switch, and it’s sometimes referred to as modified cut-through. In FragmentFree mode, the switch checks the first 64 bytes of a frame before forwarding it for fragmentation, thus guarding against forwarding runts, which are caused by collisions. Store-and-forward In this mode, the complete data frame is received on the switch’s buffer, a CRC is run, and, if the CRC passes, the switch looks up the destination addres
