For example, to assign the IP address 192.22.3.44 and sub-net mask 255.255.255.0 to Ethernet interface 1/1, do the following.
1. At the opening CLI prompt, enter enable.
device> enable
2. Enter the following command at the Privileged EXEC level prompt, then press Enter. This command erases the factory test
conguration if still present.
device# erase startup-config
CAUTION
Use the erase startup-cong command only for new systems. If you enter this command on a system you have
already congured, the command erases the conguration. If you accidentally do erase the conguration on a
congured system, enter the write memory command to save the running conguration to the startup-cong le.
3. Access the conguration level of the CLI by entering the following command.
device# configure terminal
device(config)#
4.
Congure the IP address and sub-net mask for Ethernet interface 1/1 by entering the following commands.
device(config)# interface ethernet 1/1
device(config-if-e10000-1/1)# ip address 192.22.3.44 255.255.255.0
Syntax: enable [ password ]
Syntax:
congure terminal
Syntax: [no] ip address ip-addrip-mask [ secondary ]
or
Syntax: [no] ip address ip-addr/mask-bits [ secondary ]
Use the secondary parameter if you have already congured an IP address within the same sub-net on the interface.
Enabling and disabling the interfaces
By default, all interfaces are disabled. To enable an interface, you must enter the enable command at the appropriate interface
conguration level of the CLI. For example, to enable the management interface, enter the enable command at the management
interface conguration level of the CLI.
device(config-if-mgmt-1)# enable
Syntax: enable
You can disable each of these interfaces using the disable command at the appropriate interface conguration level of the CLI. For
example, to disable the management port, enter the disable command at the management interface conguration level of the CLI.
device(config-if-mgmt-1)# disable
Syntax: disable
NOTE
For security reasons, by default, the telnet server is disabled on the devices. To enable the telnet server and allow access
through telnet to the device from an external host, execute the following.device(config)# telnet server
