Manually Assigning Ip Information; Checking And Saving The Running Configuration - Cisco 3750G - Catalyst Integrated Wireless LAN Controller Configuration Manual

Checking and Saving the Running Configuration

Switches B through D retrieve their configuration files and IP addresses in the same way.

Manually Assigning IP Information

Beginning in privileged EXEC mode, follow these steps to manually assign IP information to multiple
switched virtual interfaces (SVIs):
If the switch is running the IP services image, you can also manually assign IP information to a port if
Note
you first put the port into Layer 3 mode by using the no switchport interface configuration command.
Command
Step 1 configure terminal
Step 2 interface vlan vlan-id
Step 3 ip address ip-address subnet-mask
Step 4
exit
Step 5 ip default-gateway ip-address
Step 6
end
Step 7 show interfaces vlan vlan-id
Step 8 show ip redirects
Step 9
copy running-config startup-config
To remove the switch IP address, use the no ip address interface configuration command. If you are
removing the address through a Telnet session, your connection to the switch will be lost. To remove the
default gateway address, use the no ip default-gateway global configuration command.
For information on setting the switch system name, protecting access to privileged EXEC commands,
and setting time and calendar services, see
Checking and Saving the Running Configuration
You can check the configuration settings that you entered or changes that you made by entering this
privileged EXEC command:
Switch# show running-config

Current configuration: 1363 bytes

Purpose
Enter global configuration mode.
Enter interface configuration mode, and enter the VLAN to which the IP
information is assigned. The VLAN range is 1 to 4094.
Enter the IP address and subnet mask.
Return to global configuration mode.
Enter the IP address of the next-hop router interface that is directly
connected to the switch where a default gateway is being configured. The
default gateway receives IP packets with unresolved destination IP
addresses from the switch.
Once the default gateway is configured, the switch has connectivity to the
remote networks with which a host needs to communicate.
Note When your switch is configured to route with IP, it does not need
to have a default gateway set.
Return to privileged EXEC mode.
Verify the configured IP address.
Verify the configured default gateway.
(Optional) Save your entries in the configuration file.
