Switch Commands
On the CCIE Routing and Switching (R & S) written exam, you need to know general switch
commands and their functions, which are similar to router commands. This section covers
commands of the Catalyst operating system (CatOS). The switch command that is similar to
the router command write erase is clear config all . Example 3-19 shows a sample of this
command. The CatOS clear config all command erases the configuration stored in NVRAM.
On routers, write erase is the command that erases the configuration in NVRAM.
Example 3-19 CatOS clear config all Command
Console> (enable) clear config all
This command will clear all configuration in NVRAM.
This command will cause ifIndex to be reassigned on the next system startup.
Do you want to continue (y/n) [n]? y
........
.............................
System configuration cleared.
Console> (enable)
Passwords are configured in the Catalyst with the set password and set enablepass commands:
set password password
set enablepass password
Use the command set interface sc0 ip address mask broadcast to configure an IP address for
sc0, as shown in Example 3-20. The message returned by the switch tells you which parameters
changed. The sc0 interface is an in-band management interface that handles SNMP, Telnet,
Cisco Discovery Protocol (CDP), Virtual Terminal Protocol (VTP), and the Spanning-Tree
Protocol (STP).
Example 3-20 Configuration of Interface sc0
Switch-A> (enable) set interface sc0 172.16.19.5 255.255.255.0 172.16.19.255
Interface sc0 IP address, netmask, and broadcast set.
Switch-A> (enable)
Use show interface to check the interfaces, as shown in Example 3-21. The show interface
command displays the configured sc0 interface and its status.
